LG's Zenith-branded DTT900 Digital to Analog Converter Box

Yes the Panasonic DVDR EZ-28 has a great tuner for PQ. I wasn't kidding when I said on a 720p channel it actually looks better than my TV's built in HD tuner. Note the way I have mine setup the DVDR upconverts the signal to 1080i before going into the TV, not that I'm a big fan of upconverting but I thought I'd mention it. 480 and 1080 channels are both better than the Zenith, but not nearly as much difference. The both beat analog by leaps and bounds.
It sure sounds like multipath problems that you're having. With the signal strength jumping all over. I actually got this worse on my TV and my Panny DVDR while the Zenith was quite solid. I do notice that the Zenith signal strength meter does react quicker to signal changes than the other two devices. Maybe that's what's going on. On the Zenith does the picture ever drop or freeze, or does the signal strength just vary? If it doesn't I'd be tempted to just ignore the meter and enjoy the better PQ.

Edit:One odd thing I forgot to post on my comparison was the fact that even though at times the PQ though the Panny tuner was sharper it also had a tendency to macroblock with fast moving objects, yes even watching live not on the DVD. It seems whatever Panny's do to get the great resolution they do it at the risk of the occasional macroblock. Personally I prefer a sharper picture even if it means the occasional block, but others may differ. Personally I think it's odd that just watching TV through the Panny tuner would cause blocking but I noticed it more than just watching the same program through either the Zenith, DS, or my TV's tuner.

That is not what the "PBS post" says. It's not saying they "hear the problem over the RF modulator set to left channel audio", it is not a referrence to the issues with the "Left channel audio" discussed earlier in this thread.

Instead it's talking about something else. It's saying via the (mono) RF output, Right channel audio of any sort from a source(such as the discrete Right channel audio from a DD 2.0 source) is not being mixed with the left channel audio, such that all you get output via the RF modulator is the Left channel audio from the source.

And again, I'm not making that claim, I can't vouch for it's accuracy, I just posted a link to the info about it.

Quote:
So setting the mono RF output to left only would definitely make the problem stand out.
In the menu settings of my unit (DTT900 - Mfg. Jan 08), there is only an option to change from "Stereo" to Mono. Update: Well I just checked it, and via the RF output, setting it to "stereo" noticably lowers the audio's output level vs setting it to Mono ... I Wonder if perhaps the "PBS post" could be referring to *only* the "stereo" setting?

I don't think there's a way on the unit to "set the mono RF output to left only", or "right only" ...

The AC3 audio source would have to contain audio on Left channel only or right channel only for that to occur, and what the "PBS post" says, is if say, a DD 2.0 source only had right channel audio, and the left channel was silent, then you wouldn't hear ANY audio via the RF modulator from DTT900 ... Again, that's not ME saying that, that's what the "PBS post" I provided a link to says ...

Quote:
The problem is NOT limited to the RF output, as proof is there in the first few postings.
I don't think anyone said it was, I certianly wouldn't, because I certianly have the issue YOU are referring to with my units via the line-out audio jacks.

And again, besides the issue brought up in the "PBS post" I provided a link to (if it actually exists at all) is a different issue from the one you are referring to .....

D'oh! I should have known better. It is the same principle with DVB-S and QPSK vs 8PSK.

OK, then I misunderstood the post. Thanks for the correction, as that is a totally different issue than the audio quality problem.

Terapid, it seems you probably have the DigitalStream DTX9900, which DOES have RF pass-through. So you don't/didn't need to degrade your signal with a splitter. Another person has commented on being able to receive analog pass-through with that device.

I see you did move over to the DigitalStream DTX9900 thread to share your evaluation there. It's at:

www.avsforum.com/avs-vb/showthread.php?t=996043

(By the way, the personnel at the Radio Shack yesterday handed me a Zenith CECB when I had asked for a DigitalStream CECB, so the folks at your RS may have done the same kind of unintentional switch on you, too. They clearly weren't very knowledgeable about the CECBs.)

Also, I'm guessing that the part after the dash might be the date of manufacture year/month/date (two digits each) for the PCB. Your box might have been assembled in Jan 2008 but the circuit board might be from a batch made in Nov 2007. However, this is pure speculation at this point.

It would be interesting to know when BobDiaz's box was assembled.

If I can open my box without affecting my ability to return it or voiding my warranty, I'll try to see what is printed on the circuit board inside.
Do you have the facilities to try reading out the 24LC256? It's just an SPI eeprom... I wonder if this contains any sort of version info. I might give this a go tonight, although I'm honestly more interested in trying to get some other sort of video out of it.

LG's Zenith-branded DTT900 Digital to Analog Converter Box

Last night I was having trouble tuning one of my local stations, so I tried out the signal meter while rotating the antenna. It beeped, but only when their was audio present in the signal. When the audio would drop out the beeping would stop.
Seems to me it the beeping should depend purely on signal strength and not stop when there is no audio.

Yes, the volume of the box is at maximum and I control the volume with my receiver.

When switching to "Mono" (I am using "Stereo"), the sound gets a little better, but I still hear the sloshy sound, but it comes from both speakers yet it's more tolerable.

I decided to pick up the Zenith DTT900. I live in Los Angeles (Studio City) and I went to my nearest Radio Shack on Ventura. They had the Digital Stream, but no Zenith. Clerk said no other Radio Shacks have them right now.

So I went to my nearest Circuit City in Van Nuys. They had 1 Zenith in stock, but the clerks HAD NO IDEA WHAT TO DO WITH THE COUPON. I said you should've received instructions on how to use this, and they said they hadn't. They completely turned me away! Not good for Circuit City! I was rather angry and felt like calling CC corporate. But it was late so I rushed over to the next closest CC in Burbank. They had 1 Zenith in stock, I was their 2nd customer with the coupon. They had no problem helping me.

And the Zenith is great! Using it with my Terk TV5 antenna, picks up all the local stations (plus multicasts), and some additional foreign language stations. Everything comes in crystal clear and sounds great! Huge step up from my fuzzy channels before. I didn't even get the local CBS station previously, so this is awesome.

Only downsides... SMART ANTENNA would be nice. I have to move the antenna slightly to stabilize a couple channels. S-VIDEO, but I don't know how big a difference that'd make. FULL EPG: the now/next is not very reliable I often get "must tune to this channel to view guide." VOLUME: It can vary a lot from ch to ch. I adjust it on my TV, not through the box. Box voume at 50 sounds about the same at 70.

I just cracked open my box and the PCB is labeled LSX300-4DM EAX3980701-071009. This is the same as BobDiaz's box which makes sense since our boxes were assembled on the same date (Nov 2007).

Since c0nsumer had a box from Jan 2008 with what looks like a newer board inside I might try to pick up a 2008 box in the next few days and see if I still have the same sound problems.

spudnk

LG's Zenith-branded DTT900 Digital to Analog Converter Box

I just called Insignia at 1-877-467-4289 as an earlier poster suggest I do. Unfortunately the CSR could not offer any troubleshooting steps (I had already tried different cables and a different input source - both TV and Receiver) and she told me to take it in to Best Buy and exchange it.

I guess I'll try to find a box with a later manufacture date than December 2007 and hopefully it's something they caught in a later revision.

Should be interesting to see what happens with these if they all have the same issue. I wonder if they give you the Government Relief Card back (mine was surrendered at time of purchase) or if you are stuck incessantly exchanging them. Or if you just get your money back but lose the card.

I did see an Open Box one when I was there. I actually was going to buy it to save a few bucks, but the price was not marked (it only had the yellow license plate sticker on it). I was instructed that they will only sell they as full price (no markdowns) because they are a part of a government program and that technically that one should not have been on the sales floor. Undoubtedly, that one was returned for the same audio problem (but that's only conjecture since I did not test it).

Are you using the TV5 indoors? If so, I don't think a Smart Antenna would be very practical. Try something like the Radio Shack 15-1892 first.

according to the label on the Insignia NS-DXA1 box, my CECB was manufactured in December 2007. Glad to say I have NO AUDIO PROBLEMS. Works great. Only gets slightly warm to the touch (7 Watts) as it's always on and connected to the VCR. The blue LED makes a great nightlight (unfortunately).

You might try one more thing before sending the box back.
This worked for me, your milege might vary.
I connected both RF and compsite output at the same time. I then switched video inputs on my ProView LCD to check differences in PQ (which were identical) . I definately had audio noise, so I switched the converter to mono and the noise did go down and the volume came up a bit. But..When I went to the TVs audio menu and changed the setting to mono the noise disapeared completely.
Like I said, this is just my situation. My TV is in a sitting room and I don't need any stereo effects for casual watching.

Uh-oh. That's going to make it more difficult to track down which boxes have problems, since mine also says December 2007 and it's definitely got the left channel audio problem.

I should reiterate that the problem is MOST noticeable when the box is receiving Dolby Digital content. So the problem is really going to "shine" when using it during Primetime (since that's when most programming is transmitted in Dolby Digital).

atrac, if you feel comfortable doing so, could you open your box and tell us the version number on the main PCB before you return it since you have a Dec 2007 box? I suspect it will be the same as my Nov 2007 box. I'd like to figure out when the newer circuit boards first started being used.

If a later rev of the board does turn out to fix the problem, we can then give people a range of manufacture dates to avoid when purchasing a Zenith/Isignia box. c0nsumer already informed us that his Jan 2008 box has an updated PCB. If you exchange your box, I would recommend looking at the packaging to find one that was assembled at the beginning of the year or later.

I tried to get photos which allow almost every component to be identified, calling out the more important ICs as I saw them.

This here, which is a full res version of the photo above, is the four-pin connector which I want to poke with later today. I'm hoping to find svideo or something similar from it. I haven't traced it at all yet, but it's proximity to the rest of the video output circuitry leads me to believe that it may be useful.

I would guess 4-pin socket is for testing the board and updating firmware in EPROM/EEPROM.

That connector is on the bottom of the FCC board. There's pads for it on the one I have. I was just looking at it and pin 1 runs to the output of the large 5v linear regulator next to the RF unit. Pin 4 is Vss. I was having a real hard time tracing the rest of it, as the board gets fairly dense behind the phono jacks.

I took a moment to try and read the 24LC256, but I did so without lifting it, so I didn't have much luck. I think that this is basically an LG FPGA booting from the 24LC256. The Macronix chip contains the software it runs, and the Hynix chip is the RAM.

I could have lifted the 24LC256 to properly read it, but it really wouldn't be that useful to me... I'd take a greater geek to do much more with it.

For those who are interested, here is the setup when I was trying to read it out.

Oh, and for what it's worth, I can't get anything with the box connected to a Comcast cable TV line. I don't have an antenna and live in a condo, so I guess I won't be using the box for much for the time being. Ah well.

In addition, I would have told the manager that I will be calling the government to let them know that Circuit City is refusing to accept the coupons. Maybe the threat of gov't would make them pony up & stop treating their customers like dogs.

And if they were still unhelpful, I would have insisted they give me a $5 or $10 coupon to compensate me for the gas I wasted. There's absolutely no excuse for such piss-=poor serviced from these ****ersx. (I hate corporations; can you tell?)

Most electronic devices, when set to mono, only look at the Right channel. Since the noise is in the left, and the TV was likely ignoring the left, you heard no noise.

Also: It sounds as if the Insignia board is a different revision of the Zenith? So far I have not heard any complains about poor sound coming from the Insignias.

I bought a DTT900 CECB today at Circuit City with a $40 coupon. It was very easy to set up, easier overall than the RCA DTA800B. RF sensitivity is stronger than the RCA. The Zenith is more tenacious at "keeping a lock" on received channels. In a truly dismal basement-level unit with a middling set of amplified rabbit ears facing out a window at street level, I pulled in 31 total channels with this unit.

I installed the DTT900 via the comp-video inputs, while keeping my RF input connected to Comcast. I was able to make direct A/B comparisons between video and audio for some local stations using the OTA feed v. Comcast. A subtle layer of video noise was present on the Comcast Cable feed; the video noise was almost totally gone when viewing OTA via the DTT900. The sound was slightly different; I'll have to try out the box connected to my reference audio gear later. The DTT900's remote is smaller than the RCA, but to my nimble fingers is acceptable.

A few neighbors are interested in testing the box on their (upper-floor) units; they were quite intrigued about the idea of really good Digital TV instead of Comcast. If enough folks are interested, the condo complex might even set up a master rooftop antenna which would be fabulous...but first I need to see if my neighbors become as enthusiastic as I am.

While I liked the RCA CECB, the Zenith seems better engineered and a more tried-and-true electronic design. Channel changes are relatively quick on both CECBs (compared with many ATSC tuners built-in to consumer-grade TVs), but the Zenith has much more flexibility and versatility. I liked being able to manually select channels. For my mono bedroom TV, I also liked being able to designate mono audio.

Originally I went to Best Buy. The BB TV assistant manager hadn't seen an actual $40 coupon before, but seemed rather stoned and uninterested in actually selling a CECB (there was a big stack of them). Not much sales commission, I guess. He told me that ALL converter boxes were EXACTLY THE SAME. His colleagues weren't real eager; they would sell me one, but with no great enthusiasm (hint: no "price match" for competitors).

As there was no discount for buying "generic" Insignia at Best Buy - and the sales staff was apathetic - I drove 1 mile to Circuit City and bought the "name brand" Zenith there. It was apparently the first coupon they had processed, they handled it without a hitch.

The Zenith is proving to be a truly good CECB, even beter than the Insignia, which is odd considering they suppose to have the same internals.

the zenith i got at radio shack is marked dtt-990?

it works ok so far.
the bugaboo?
no vcr pass through?
or do i have things setup wrong?

Are you sure ?
The Radio Shack website lists both of the following -
Digital Stream DTX9900
Zenith DTT900

Both of these are CECBs

And the no analog passthrough is a known "feature" on both of these.

Scooper

LG's Zenith-branded DTT900 Digital to Analog Converter Box

Terapin: in case my post left you confused - there is no antenna "analog pass-through" on the Zenith DTT900.

What I did was keep my cable-TV feed connected to the RF input, while connecting my DTT900 and antenna to the component inputs. I toggled back and forth between the cable tuner and the DTT900.

At this time, I probably will keep the Limited Basic Cable TV subscription because it is tied to my high-speed internet service and (due to a multi-product discount) costs me very little. But I can honestly say, the condo unit I live in never had viewable OTA. Doing without cable TV is definitely an option.

As someone who had the RCA DTA800B in my home for five days, I observed that the Zenith has much more stable OTA reception, using the exact same so-so amplified indoor antenna, than the RCA.

I just got my coupons today so I picked up two of the Insignia branded version of the LG box from Best Buy. Some observations:

1. The coaxial cable that comes with the box is garbage. When using the RF output on the box the sound had a constant buzz that was improved by upgrading the cable to RG6.

2. I live in a strong signal area and in multi-path hell with more analog ghosts than I can count on my two hands. The LG tuner still has some trouble with that environment using a basic loop antenna, which really doesn't surprise me. However, the problems are usually in the form of block errors and some audio breakup. I have yet to see the signal drop-out completely. My Samsung TV is a different story.

3. When compared with my Samsung HLR4266 using the same antenna feed (Terrestrial Digital DB2 indoors, no pre-amp, 4 port distribution amp), the Insignia sometimes has errors when the Samsung TV is perfect and vice versa. The Insignia doesn't drop-out completely like the Samsung does. The Insignia box detects and sometimes gets decoded video for Maryland PBS 22 whereas my Samsung doesn't.

4. The audio is really quiet on the RF side. It's a little louder using the composite cable. Switching to Mono audio output greatly improves the loudness in the audio output. The fact that you have to turn your TV up to the max to get useful range out of the converter box volume control is really annoying when you have other devices such as a gaming console hooked up to the TV.

5. It definitely has a very intuitive menu interface. The EZ-add and ability to tune to specific RF channels is nice. This is just my preference, but I like the small remote.

6. Although limited, the EPG is still useful. It's much better than what my Samsung HDTV delivers (only the current program and an incomplete description).

7. The print in the manual is somewhat small, which sucks for anyone who's near sight isn't great.

8. The signal meter on the Insignia with the audible meter is very handy for pointing the antenna when the tv is not visible. It's also fairly easy to quickly check the signal strength for all the channels after making an adjustment. It's also got a larger range than my Samsung does, which makes it handy for determining if you have a shot at getting a signal even when you can't get a decoded video lock on the station.

All in all, I'm really pleased with this converter box. Even with the occasional picture breakup, the digital picture blows away even the best of the analog pictures I receive. The tuner performs better than my HDTV.
So, at this point, I'm thoroughly impressed with the RF performance of this box. Now that the weather has cleared up, the Insignia box is decoding a watchable, with some video breaking up, MPT 22 off of my indoor DB2 feed (db2 no preamp -> 25ft rg6 -> coupler -> 30ft rg6 -> distro amp). Neither my Samsung hdtv nor my PCHDTV card even detect this channel much less begin to decode the video from it. For my location, this station shows up in the yellow threshold zone of the tvfool (http://www.tvfool.com) results.

Finally picked up the Zenith at HH GRegg yesterday. First card they had processed. took two employees and about ten minutes to reference their PDF instructions and figure out how to do so, but they were very polite about it. Hook up was very easy (use my own better RF cable than the cheap one included).
Prior to setup I was getting about 10 channels OTA...most not very well...now receiving about 25. On some channels noticed some high pitched noise which was fixed after switching the channel from stereo to mono. Have some audio dropout and some pixelation on a few of the more long distance channels.

Our local PBS which is a UHF broadcast wouldn't come in well until I extended the rabbit ears.

Overall very pleased with the reception.

I got an Insignia box 2 days ago. I assume the operation is very similar to the Zenith box. The only thing that I really do not like about the box is the fact that the box controls the volume (through attenuation of the signal I assume).

Having to turn up the volume on my television, and keeping it up in order to control it via the box's remote is an utter pain. Not to mention interesting moments when I switch to another source and it is BLARING.

The RCA DTA800B's mode of operation (TV Power + TV Volume) in the remote would have been preferable on the Insignia/Zenith. On the whole the Insignia is a decent box.

As you mention, the Zenith/Insignia has a variable volume output on the stereo L/R output. Does it also have variable volume on the RF output?

Zenith's DTT900 continues to impress me with excellent RF sensitivity and superior reception characteristics. PQ has been the best I've ever seen on my bedroom CRT, and I'm looking forward to installing a second box to a 1990s-vintage 27" Sony Trinitron.

The only problem I have been having with the Zenith (though it might be the broadcast channel) is on some channels I will get some random high pitch noise....you notice it with speech on the 's' and 't' sounds....though sometime it is almost constant with some music....I'm using RF....do you think the component cables would change this?

Try switching the converter audio to Mono, the noise should disapear and you'll probably get a volume boost.

Composite cabling should help on this problem. If you're using the RF cable that came with the box, you might find that upgrading the RF cable to RG6 might help as well.

The Philips Universal Digital DVD Learning Remote PMDVD6 is very useful for up to six devices. Devices may be assigned to just about any device button, say two different TVs in the same room. The Philips may also search for control codes for devices not listed in the twelve pages of common product codes (like that of my new Dynex TV). I purchased the Philips for less than $10 at a local Fred Meyer store (a Kroger-owned chain). Another Philips Learning Remote controls eight devices, and is priced under $18.

Assuming I'm understanding your question correctly, yes.

You could set the Zenith volume to a picked "fixed" setting. Then, not touch this volume control again, and control the TV's volume only.

But, I have not noticed a fixed/variable toggle setting in the menu.

Have you checked their website to see if the have the Zenith codes for the converter boxes yet? I know I can just have it learn the signal, but was hoping not to have to bother. How long does Logitech take to update their listings when new products come out?

I just checked and it is indeed in their database, but the soft buttons are really poorly configured. You'll have to do a lot of customizing.

I checked with my remote (model 520) and the the Harmony Remote software/ website already has the codes for the Zenith DTT900 converter box.

I went ahead and added the device in my remote. It worked fine to turn on the box and do most of the basic functions. The remote has codes for a bunch of activities that are not available on the box Like (1080i, HDMI, 480P) etc.

I suspect that they just ported over the codes for another more sophisticated Zenith or LG set top box. It should work fine for you.

I believe that Logitech updates the code database very quickly.

Picked up a pair of DTT900s at Circuit City Saturday night, and I've got to say, I'm very
impressed.

Among other things with a pair of rabbit ears it sees at least two channels my TiVo S3 doesn't even see a trace of.

Very nice, very easy setup that should work well for most anyone.

My only wishes are that it had S-Video, and passed the input antenna signal when
powered off, like a VCR.

Stereo audio over RF would have been nice but I doubt it's possible at this price point.

Zenith box reception first impression: Set up went flawlessly without ever looking at the instruction sheet. I'm using powered rabbit ears. I discovered six things unrelated to the box. 1. Digital local stations, full scale on UHF, appeared to be keeping their on screen analog channel numbers. 2. The digital stations in communities 20-30 miles away are not readable on rabbit ears. 3. Our local ABC station, assigned to digital channel 10, was completely unreadable due to their extremely reduced digital power as they try to protect some analog station(s) on the that channel. 4. Some digital stations are on directly adjacent UHF channels. 5. The digital channels in my area only are transmitting just one subchannel. Their digital video fidelity is wonderful. Some stations fill out the 4:3 screen, some shrink the image within the 4:3 screen. 6. Some digital stations are transmitting program names, some are not. BTW: I read that after the analog shutdown some of the digital channel assignments will change.

I have the same problem with my Zenith as well. I even tried exchanging it for another unit but the problem persisted. I've tried composite and RF cables as well as running the audio into my TV and surround receiver but no luck.

I'll try switching the audio to mono, but it would be nice if I didn't have to give up stereo sound.

I really like everything else about this box though. I've tried the Magnavox and RCA models from Walmart and the Zenith is much better all around. It has better construction, a better interface, and a better remote. However, the other boxes had perfect sound.

Unless I can fix this problem I think I will have to return the Zenith box.

Over the past couple of days my Insignia CECB has lost signal, then after a few seconds reacquired. I would have blamed the signal, but when it loses signal, it losses signal for ALL channels. At the same time, my Samsung does not lose signal.
Finally, last night it lost signal for good, or at least I thought. I was watching TV and the picture froze, then it lost signal. i tried changing channels, no joy. Checked the Samsung, signal is fine. Went back to the CECB, ran a scan, ZERO channels. Gave up watched from the Samsung instead. An hour later, no change.
Got up this morning, ran a scan again, all is back to normal.

FWIW, this problem did not surface until I started using the RCA composite connectors exclusively. Before I used the coax with no issues other than crappy sound.

Should I take it back to BB and exchange?

Long time lurker, first time poster.

My Zenith box, manufacture date Nov 2007, is connected to my RCA 32" model number F32730SB analog TV via the composite connections.

I'm curious about grainy color transitions, and if anyone else has had this problem: instead of smooth color gradients, the transitions are noticeably grainy/blocky.

Imagine using a 16-bit graphics card on your computer instead of a 24-bit one, so that your available color palette is only thousands of colors instead of millions. A 16-bit graphics card will render a color transition much less smoothly than the 24-bit one. (Try setting your PC's color palette to just 256 colors if you want to see an absurd amount of grainy transitions on a computer screen.)

I'm trying to determine whether my Zenith CECB delivers grainy colors, or my RCA analog TV is the weak link in the chain. The TV is a hand-me-down; it's about 12 years old. There' not much info available on the internet about this model TV. Before I got the Zenith CECB, the analog broadcasts rendered well-enough without this grainy color transition. I really can't buy another TV right now.

(Interestingly, my Zenith doesn't seem to have the audio problem on the left stereo channel. I can't swear to this because it may just be my hearing...I have mild high-frequency hearing loss from working in a very noisy environment some 20-odd years ago.)

I purchased my Zenith with my coupon on March 5th from a local Radio Shack. I've already exchanged it once at a *different* Radio Shack in my area, but got the same vintage box (Nov 2007). I've got just over a week before my 30 day refund/exchange window closes.

I really like the Zenith DTT900 otherwise, so exchanging my Zenith for the Digital Stream DTX9900 is a last-resort option. I can live with the grainy color transitions if I have to.

Thanks so much in advance.

Welcome 2 Shoes.
You're seeing MPEG compression artifacts. It varies by station dependent upon the format and number of channels the station has in their digital stream. You'll see the same on any box you try with a given station.

All of these shows are 5.1. Do you think that would be the issue? I switched from mono to stereo on my Zenith box and messed with the settings on my AV receiver with no big change. No other station had these issues and CBS news wasn't affected later on or this morning.

Anyone else hear these broadcasts? Maybe it was just a local transmission issue.
"Sounds like" a classic case of the "Missing Center Channel" problem.
[Which may or may not be related to LG/Zenith/D-S clicking problem...]
To verify, compare to an HD system by putting your ear next to the center speaker.

=========================================
BTW: Since it depends on local station equipment configurations, it occurs in
some network stations and not in others....and varies from program to program.

Dolby Decoder at your local station outputs six surround signals: L/R, LS/RS, CTR/SW.
Stereo outputs are also formed from these signals: Lt/Rt, where each "Total" signal
contains Center and SW (subwoofer) signals (but not LS/RS surrounds).

The "Missing Center Channel" problem occurs when L/R (only) is transmitted
in broadcasted DD5.1 signal, rather than Lt/Lr. [Rarely, I also hear LS/RS.]
Hence, L/R is missing Center and SW (bass). [Wolf (Stereo) in Sheep's (DD5.1) clothing.]

Sometimes I suspect Center channel is OUT-OF-PHASE with L/R...or is it Lt/Rt???
YMMV...there are various (manual?) "fixes" overriding Metachannel controls....
so I hear different defects....

This problem is due to mishandling of Metadata controls and local decision to
ALWAYS transmit DD5.1 to avoid DD2.0/DD5.1 (manual?) reconfigurations
every time their (Stereo) Ad Splicer inserts a commercial. And may or may not
be "fixed" by a conscientious local engineer for some favorite programs:

Thank you for the kind "welcome aboard", Bob.

A follow-up question if I may. I'm sorry if I wasn't exactly clear in my previous post.

Are the MPEG compression artifacts present even if the image is a static one? What if the image on the screen is a non-moving, solid color graphic? One that's essentially a high resolution JPEG or perhaps a GIF. But as you sweep from the left side of the image to its right side there's a transition from, say, a dark blue to a light blue. Shouldn't the transition from the dark hue to the lighter hue be smooth?

What I'm seeing is the choppy transition that you'd get on a non-interlaced computer screen set to a screen resolution like 1024 x 768 or higher, but with the color palette set to somewhere between 256 colors and 65,536. Most computer monitors and graphics cards these days can render millions of colors. Not so just 10 years ago. And because my TV is over 10 years old, I wonder if it's to blame, and not the Zenith CECB.

Sure, with MPEG compression there are all sorts of pixelation artifacts based on the bit rate of the signal. But I'm not convinced that I'm seeing compression artifacts in the context of my question. I mean, I do see compression artifacts in other aspects of my TV viewing experience. But imagine a computer desktop wallpaper of a mountain view, and you try to render all the shades from the rich blacks of the shadows to the subtlest pale blues and whites in the sky with a limited range of shades. It'd just look choppy.

The choppy color transitions I'm seeing happens on all the channels, regardless of what (I speculate) the compression of the particular station's signal is. I also don't think this is due to any aliasing of the interlaced rendering on my analog TV, because it seems to exist vertically as well as horizontally. But heh, I don't know. That's why I appreciate all the helpful advice and information here.

Thanks again for the welcoming words. Cheers. --2shoes

What you describe sounds like "color banding":
http://dvinfo.net/canon/articles/article10.php
http://easyhdtv.blogspot.com/2007/02...v-display.html
Digital TV (also DVDs) use 24-bit color, which is 8-bits for each of three colors.

I'm wondering if the comb filter in your 10-year old TV might be the culprit...
or maybe the converter box....

Hi.
Help! Is there someone out there to tell me why I get a (60Htz?) noise on my analog TV after installing a new Zenith DTT900 digital TV tuner converter box?
Thanks in advance.

Try covering the LED with a piece of black electrical tape or just unplug the box from the electric outlet.

Or put some scotch tape over the LEDs and use a felt-tip marker to make it
dark enough you aren't bothered at night, yet is visible in daytime.

If you overdo it the first time, try again.....
PS: Try same color as LED.

Could be a ground loop problem.
First try to reverse the prongs on the
AC plug at first the TV, LISTEN and then the converter box if it persists....

The plug polarization may prevent you from doing this on one or both units.
Since some old TV's have a "hot" chassis, don't try to defeat this safety feature.

holl_ands,

Thank you, thank you, thank you for the links. (I had to snip them out of the quote since I don't yet have 3 posts so that I can post hyperlinks.)

Color banding is exactly what I see. Sure is easier/more accurate to say color banding than to say grainy color transitions. Gotta love key words and tricky phrases.

Anyhoo, is anyone else seeing color banding with their Zenith box? If not, I'll look into the comb filter on the composite video.

holl_ands, thanks again for upgrading this newbie's knowledge.

I'd recommend turning the Comb filter off (set sharpness to 0).

The RF coaxial out. Once I switched to mono, the noise was gone.

Aren't you glad we discontinued that "inferior" analog so we could enjoy the "superiority" of bad audio encodings, out-of-sync video/audio streams, and buzzing from the left channel?

Yay.

Roger - I disconnected the coax all together in favor of composite. However, that introduced a whole other problem, far worse than the sound issue, which I detailed here: http://www.avsforum.com/avs-vb/showt...0#post13468990

After I ran the early morning rescan and re-acquired all my channels, when I came home that night the channels were gone again. It had not been turned on or used all day. A second rescan brought them back, but for how long?

Since no-one else seems to have reported this issue here, I'm hoping it's just isolated to my CECB, and that if I exchange it I will get a more reliable machine. FWIW, my Insignia has a date of Dec 2007 on the back.

Whidbey

LG's Zenith-branded DTT900 Digital to Analog Converter Box

I had a left over Reward Zone coupon so I picked up the Insignia at Best Buy on Tuesday. It works as described. Haven't heard the audio problem connected to a SONY old tube stereo TV about 12 years old. Could be my hearing.
I connected it through the "youtube" antenna I built. Even in the basement where I started testing it found all of the local channels and sub channels quite easily.

Anybody see the broadcasters association ad? It shows a snowy analog picture and beside it a clear, precise picture of the same scene. Saying that digital is that much better. I hate to tell them that if the UHF signal was that poor the digital would be blank.

LG's Zenith-branded DTT900 Digital to Analog Converter Box

I bought the Zenith DTT900 last night at Circuit City with a coupon, and here are some first impressions.

CC had several DTT900's on the shelf. Only one looked like the box had been opened, all others looked fresh. All had January 2008 manufacture date marked on the outside of the box.

The cashier said that mine would be the first coupon sale she had done. Had CC given them training on how to do it? "No," she said, "but they told us the coupons were coming." Her first two tries to make the coupon work failed - trying it like a credit-card, then like a manufacturer's coupon. Eventually with the help of a supe, she figured how to make it work: by treating it as if it were a credit-card with a $40 credit limit. She charged the first $40 of the price to the coupon-credit-card, and the remainder to my personal credit-card. Only took about a 2 minute delay to figure it out. (This morning when I checked dtv2009.gov, it already knew the coupon had been used. She offered me the coupon back, but I let her throw it away for me.)

Brought the box home, and first tried out the remote control which had you press Power and CH^ repeatedly until it controlled your TVs power. Only took 22 presses and then it was powering my RCA-labelled 27" CRT up and down just fine. And they included a battery! The remote control didn't feel uncomfortable to use.

Because of an earlier post that I though was neat, I looked at my watch as I took the DTT900 out of the box. Then I connected my 25-year-old-in-the-attic antenna lead -> DTT900, and DTT900 composite video -> VCR line in; and 4 minutes and 45 seconds later I had the Menu on my TV. That included unwrapping time. Woulda been quicker, but I inadvertently unplugged power to my VCR for a bit. Composite video cables (which I used) and RF cable (which I didn't) were all included.

Initial menus were just like the QuickStart guide said they would be.

I wish I wish I wish I had timed the initial channel scanning, but by the time I had thought of it, the scan was almost done. Maybe a minute or two to find 22 channels. I'm north east of Atlanta, about 17 to 30 miles from most transmitters. OTA I got maybe 6 stations clearly, and another 6 with various degrees of snow.

DTT900 picture looked great, only saw one instance of picture breaking up once thru the whole night. And since that was on one of the subchannels of a local Spanish station, that doesn't bother me. (I don't speak Spanish).

I'm not a video expert, but the picture seemed great to me. I've always been OTA at my present location, and I'm used to which stations are clear and which are snowy and multipath. Of course, what I received with the DTT900 was SD to my TV, but some of the best SD pictures that my RCA has put out.

Stereo passed thru to my big stereo receiver sounded just fine. I, myself, didn't hear any of the left-channel artifacts discussed on this board. But two things about that: (1) I'm not knowledgable enough with programming available to know what's got the 5.1 that I understand is necessary to hear the problem. (2) My half-century old ears have a bunch of loss at the high end. No doubt due to my abortive early career in rock-n-roll. (But looking back on it, it WAS worth it to stand in front of Jack Bruce's speaker stack during that concert 30 years ago!)

For the letterboxing and sidebars, I started out by trying to analyze each picture to decide how to view it. ("Lessee, this is the News Hour, which I know is 16:9, but is it HD, so should I choose...") Eventually I changed to just mashing that ZOOM button 'till the picture looked like how I liked. There are only a few ZOOM settings, anyway.

The same can't be said for the closed captioning though. Turning on CC took only one press of the "CCD" button. Which was good. But to get it back to the "Off" setting you have to cycle through all those services. That's really my only user-interface-type complaint so far.

Tonight I'm going to take the same box to a friend's house just east of Atlanta and try it out on a pair of rabbit ears. If anything interesting comes of it, I'll add it.

Hey, folks, sorry if this post was too verbose, but while I was reading posts on this board trying to decide what to buy this is just the sort of report that I was looking for. So, I thought somebody else might like one! 8-)

So, for $63-40=$23 I've got some more channels and a much clearer picture. I'm happy.

Be seeing you,
Jokester

Some people have been able to get the $40 refunded to their coupon when they returned a box. I'd suggest keeping the redeemed coupon card just to be on the safe side.

You can turn off the digital closed captioning by just going to "Service2" since typically nothing is actually broadcast on Service 2, but if you want to turn the captions back on again, you would have to push the CCD button 13 times because you'll be on Service2 and you have to go through the rest of the 6 services, 4 CC option, 4 Text options, and through the Off option to get to Service1. When you change the channel, the captioning will go back to what was set within the menu.

A quicker way to turn off the digital captioning momentarily without losing the picture is to push another button on the remote, like the center button (which displays the time and the channel number on the side). That's useful when the captions are covering up something you want to see. (However, with advanced closed captioning, you can also choose a transparent or translucent background and small captions which would cover up even less of the picture.)

No need to apologize--thank you for sharing your initial experiences! Except for the audio issue, I'm happy with the Zenith for the most part.

If you've indeed experienced a degree of hearing loss, as indicated in your full review, then you'll probably never have to worry about this issue...when viewed on a graph, it seems limited to 11,000 hz and above.

I tried your sugestion to no avail. When I turn off the Zenith box with the analog TV on a loud (switch noise?) coinsides with the screen going blank. Sounds like the sound of an amplified arc. My house does not have a third (ground) conductor in the outlets. Can I tap one of the 110 Volt conductor to try grounding the coax cables?

I am going to ask Dr. Rudy Wells to adjust my bionic hearing so I won't hear those upper frequencies.

That seems more likely to actually happen vs. LG admitting there's a problem with these boxes and recalling them or repairing them.

More in the DTT900 saga.

I moved that same box to an area just east of Atlanta, but closer to the largest antenna farm. Summary: it worked great.

The "rabbit ears" turned out to be some old RCA-branded indoor non-amplified thingy that looks like a flat frisbee that sits on top of the TV. It's NOT an ANT585, but it sort of looks like the flat plate part of an ANT585 with the flat plate part lying horizontal. Or it looks like a square Flying Saucer or something. Analog OTA reception had degraded lately there, to the point where the TV was almost too snowy to watch on every channel.

Anyway, I brought my DTT900 and plugged it in, rabbit ears -> DTT900 and DTT900 RF out-> old TV. It still had the channel lineup that I had scanned at my home, which was a good thing, because I forgot to bring the remote control.

In east Atlanta the DTT900 showed a great picture on every channel that was already in the channel lineup. There was also one channel that was FOUND at my house but never had enough signal to display. It displayed 100% at the new location.

The feature of the DTT900 that really saved the day (and the reason why I've posted again) was the fact that the DTT900 had channel up/down buttons on the STB because we could tune it without a remote control ! When I read other reviewers talk bad about other models because they had no front-of-the-box controls, I gave it short shrift. But after experiencing viewing without a remote, I see that's an important feature. And what about when the remote is lost down inside the sofa cushions ?!?


I'm off to CC tonight to get another DTT900, and just for kicks I'm going to see if I can get it to do an initial channelscan without a remote.

LG's Zenith-branded DTT900 Digital to Analog Converter Box

quick question, i have this hooked up to plain old rabbit ears antenna with aluminum foil at the tips. i live a couple miles from an airport, so airplanes fly overhead every 15-20 minutes and it affects the reception for a couple of seconds.

is there way to limit the cut-outs whenever a plane passes through or am i stuck with it?

thanks.

MeeZ01

LG's Zenith-branded DTT900 Digital to Analog Converter Box

I've noticed that when I test with rabbit ears, a plane flying overhead can also break up the signal. I almost never see this with an outside antenna.

If you can set up with an outside antenna (or antenna in the attic), this could solve your problem.

Try a better, outddor antenna. usually it's multipath that's so fast the receiver can't correct for it.

I was calling to see if thry would fix the issue before I buy one

Since you mention a coax, I presume you may be using an OUTDOOR antenna.
If so, the bottom of the antenna mast must have its own grounding wire and
at the entry point of the coax to the house, there must be a coax spark gap
arrestor, which must have a ground wire in accordance with local NEC requirements.
[PS: Attic and indoor antennas do not need to be grounded.]

Sooooo, the coax should ALREADY be grounded as part of the mandatory
NEC requirements, which will drain off static electricity build-up and provide
some protection against nearby lightning strikes....
And protect YOU against an insurance agent denying a claim if there's a "problem"....

Antenna installation guidance is given here (see Chapter Six):
http://www.winegarddirect.com/pdf/manual_PR_models.pdf
http://www.solidsignal.com/manuals/AntInstallGuide.pdf
The "antenna discharge unit" is a spark gap arrestor, aka "ground block":
http://www.radioshack.com/product/in...entPage=search

=========================
Let me tell a little story first. While working on something electrical in my
daughter's mid-70s vintage track house I noticed there was several volts of AC
between "Neutral" (white) and safety ground (green)....by throwing switches
I traced it back to her old dishwasher (probably some EMI filters on the motor).

Okay, no big problem.....until much later I swapped in a motion sensor
porch light after doing the usual AC voltage safety check. I guess the
dishwasher pump finally came on, cuz I felt power (about 20 VAC) on the wires!!!
[Recently, her old dishwasher was replaced....hopefully no more problem.]

Moral of the story: The "Neutral" wire carries the RETURN current and hence
will be lifted ABOVE ground by V=IR. If you short "Neutral" to a ground other
than the originating transformer, you cause a ground loop in the power system,
whereby significant return current could be trying to flow "up" the coax:
http://www.psihq.com/iread/strpgrnd.htm

==========================
Hence, various ISOLATION techniques are preferred to combat ground loops.

There are 120 VAC to 120 VAC Isolation transformers that can be used
on the TV and/or converter.

There are audio isolators for the L/R interface:
http://www.radioshack.com/product/in...entPage=search

And there are coax isolators that work wonders for problematic cable systems:
http://www.buy.com/prod/pico-macom-t...202749807.html

More info on coax isolators and power isolators can be found here:
http://www.avsforum.com/avs-vb/showt...&#post10374027

==========================
It is important to determine whether the coax is contributing to the problem.
Can you use an alternative, temporary antenna and coax to receive DTV???
If you still see problems, it's not the coax.

If you have an AC volt meter, you can measure voltages between each
component and also to true ground with and without interconnecting cables
to help isolate the source of your problem....

In addition to its overall performance, I'm impressed with the Zenith's LED, especially in a darkened room. When the Zenith is powered off the LED shows red. When it's powered on the LED shows blue.

The LED's shape brings to mind the light seen behind Gort's opened visor just before the ray zaps something or someone in The Day The Earth Stood Still.

No problem. I explained it in more detail in this thread I started.


http://www.avsforum.com/avs-vb/showthread.php?t=1020326

I want to keep my HD cable box for that display. With it I can get 25 or so HD channels, including all my local OTA HD signals , with the exception of CBS.

My local CBS affiliate and my local cable provider are in a royal pissing contest over fees to carry the local CBS HD signal on cable. So all I can get for CBS is a low strength analog signal on my HD cablebox that looks like doggy poo on that 57 inch set. All other cable analog, digital digital and cable HD channels look fine. I'm also missing a couple of the local sub PBS digital channels.

Watching the Masters golf tournament pretty much sucked, especially when I went from the HD ESPN feed to the lousy analog CBS feed from my cable provider

The stuation may resolve itself soon enough, or I will move to Direct TV in the fall so I don't really want to buy a real HD capable ATSC tuner. For local advertsing business reasons I need to keep cable and the SA 8300 HD box at any rate.

So I basically want to use the CECB for just grabbing the OTA ATSC signal at 480i and using my HDTV to upconvert that signal back to 1080i60. I know it will not be real HD, but it will be better than what I get now.

The DTX-9900 has a similarly bright LED that goes red to green. What I really wish is that it had an LED channel dsiplay on the box. That way I could set it for my DVDR without having to turn on the TV & DVDR to see it's channel setting. I don't see any CECB's with a channel display.

He wants the OTA signal using the Zenith box instead of the horrible cable signal. This has nothing to do with using the cable QAM signal.
