Problems with Panasonic DMR-E85H

Hi all,

I've had grief with a Panasonic DMR-E85H DVD Recorder. The machine's only about 18 months old but only 4 months out of warranty I've had problems and wondered if anyone could help.

I've had it assessed for repairs but the quote is £180 for a replacement DVD-RAM drive and PSU which seems uneconomic.

Problems started when the machine would reset and go into self-check when dubbing from the hard drive to DVD-RAM and DVD-R discs. It would get to about 99% done and then restart.

I took it in for repairs with an authorised service centre who said it was likely dust. They cleaned the machine out and said it was working but may need a replacement DVD-RAM drive to be sure, which I didn't go for.

1 month later the machine was playing up again, restarting into self-check when firing up for a timer recording. Shortly after this the machine locked and has been unresponsive, going into self check and turning off whenever switched on. The service centre advised that it needs a new RAM drive and PSU. However they did tell me they'd the same problem with another customer's DMR-E85H that had to be returned to Panasonic for repairs. I feel that they're not doing the same for me as I'm out of warranty.

Can anyone advise a remedy or suggest a supplier for parts, and if anyone had anything in the way of a service manual that would be a big help. £180 is too much to pay for repairs when I could get a newer, higher specced model for slighty more. I figure if I can get the parts I'll have a crack at replacing them myself.

Problems with Panasonic DMR-E85H

Hi Guys,
Interesting thread.
I have an E85 that is about 2 years old.
It has been tempremental with DVD-R almost from the off so much so it has not been used to record to them very often, unfortunately it has now decided it does not recognise blank DVD-R. i have not got a DVD-RAM disc.
The commercial discs and cd it reads fine and the HDD is also OK it is particularly annoying as i want some data on the HDD put on DVD. It seems that others have had this problem and there appears to be little that can be done.
I have lost faith in Panasonic after such a poorly constructed machine.

Hmm. I'm not too sure it is just a 12v regulator. Judging by it's cousins (ie 6653 etc), it looks like it may the chopper for reducing the mains side to something manageable. In which case and after a little thought, I think it's probably best to swallow the ?13 price tag and play safe.

Btw, I'm sure it is just a heating problem at first, but the way the fault develops i suspect the chip ends up fried as the machine doesn't bother starting even when cold!

I'm pretty sure if you purchased a 100 or so then the price would drastically reduce. You may be right in accepting ?13 as a small price to pay for a repair.
Saves you the time of finding a suitable alternative plus needing a firm which will supply a one-off item.

Still - the firms which will supply a one off item and then charge almost as much postage as the product costs annoy me. Probably why I have never used e-bay (and don't intend doing either!).

Problems with Panasonic DMR-E85H

I've just joined the broken E85 club too. Mine started mis-behaving last week as I inserted a DVD... it just went off and went into an endless reboot cycle.
My machine is 2 years old by the way and has seen very, very little use.
I seriously hardly use it... so this is obviously a design fault.

I've just dis-assembled the machine to see if I could do the job of replacing the guilty component before I order it. I didn't want to order it only to find out the job was too difficult!!
Good news... the job doesn't look to tricky really.

Removing the PSU board took me about 10 minutes, and the solder points on the component (there are 5 of them) look sufficiently spaced for me to try soldering myself.

I really couldn't be bothered taking it to a dodgy TV repair shop, and I'd rather take full satisfaction from fixing it all myself.

The part should arrive next week, so I'll let you know how I get on.

Thanks everybody.

Problems with Panasonic DMR-E85H

Hi Jules... I think the hardest part of the job would be to remove the old chip without overheating the other components on the board....I sometimes have problems removing old solder using desolder wick (although a soldering iron with temperature control or a thermostat might help). Getting advice about soldering Surface Mounted Components through the Internet may also help....eg. One website suggests painting flux (using a flux pen)onto the IC's pins (or legs) and onto the pads onto which the IC will be mounted and then tin the pads with solder. They said that you don't apply heat directly onto the IC pins but to the solder on the pads since too much heat may destroy the IC....although you run the risk of making a dry joint if you don't heat up the solder enough. They also suggest using a "low melting point solder" (which has some silver in it) which is supposed to flow better than standard 60/40 solder but I've had problems using it because it tends to "ball up" when I heat it (however this could be my soldering iron at fault). Also, it's a good idea to "tack solder" a corner pin, check the alignment of the remaining pins (are they all still sitting on their respective pads ?) and then solder the pin on the opposite corner, after which you can solder the remaining pins and then redo that first pin.

So far my only experience with soldering Surface Mounted chips is with building a "video stabilser" kit that has 2 of them however this didn't involve removing any old chips or old solder. Anyway, I think I'll try "murdering" a couple of SM chips on some obsolete computer video or sound card before I try replacing my STRG6353.

I've just seen this thread, and it reminded me of problems I was having with my E85 at the end of 2005. [original thread]

It turned out to be the power supply as mentioned here, but there was also an upgraded version of the firmware posted by a member called illustrator that made the unit more reliable, and accept faster discs. It might be of interest/use of some people, though the newer batches probably came with the updated firmware.

There are instructions on the full thread on how to check the firmware version, and how to burn the firmware disc.

I remember some people lost their multiregion facility when they updated theirs, but mine was left in place.

As with all firmware flashes, read the instructions, and don't do it if you're not confident!

rich_jtg

Problems with Panasonic DMR-E85H

For removing the old solder joint I had an idea... get an assistant to 'lift' the leg as I quickly 'dab' the joint with the iron. That way, as soon as the solder has melted it should come free and thus avoid the chance of overheating.

I've also read that placing a crocodile clip on the pin you are soldering acts as a heatsink and reduces the risk of overheating.

I've soldered a few cables in the passed, and whilst this will certianly require more care, I think I've learned a few things.... particularly that you really don't need to hold the iron on the joint for more than a fraction of a second for the solder to melt. Just a quick 'dab' usually does it, and if it doesn't than wait for it to cool before having another go. Repeated attempts in quick succession are probably what will overheat the component.

Jules

Problems with Panasonic DMR-E85H

As this is a TO220 profile chip its a fairly large one as IC's go and should prove no trouble in removing and soldering in a new item.

A 25 watt soldering iron should be OK. If you have one you could use a vacuum solder sucker to remove the old solder.

Use some fine cutters to chop the five legs off the old chip first and remove it. This should aid the removal of the old leg bits prior to insertion of the new component.

ROYOLD

Problems with Panasonic DMR-E85H

Yes, Roy. I was just about to suggest cutting the old chip out before desoldering. The use a vacuum pump the clear the holes after removing the cut off legs (i use a pair of fine pliers to do the removal and clamp the pcb using a 'croc-clip vice' as a third hand). I've just ordered the part from Nikko and it does pain me to have to pay all that for not much!

Btw, Roy, I fully agree with you about Ebay, I don't trust it as far as I can throw a Panasonic DVD recorder.

Annie_M

Problems with Panasonic DMR-E85H

Hi,

Well my 85 has also given up the ghost, went wrong just efore Christmas, endless reboots and not releasing the disc from the tray, anyway managed to power it off and then back on and the tray opened (had left it off prior to this for 36 hours) also had the problem of it switching itself off.

Anyway, I took out an extended gaurantee on the machine, well after chasing Domestic and General who also managed fubar the policy details, got a phone call today to say they are writing the machine off.

Fault is the power supply board, now can this be replaced? if so does anyone know the part number or what I need to order, as I'm going to ask for the recorder back as its only 2 years old and like several others on here had very little use.

I bought as part of the SCHT-37R set up, now I've no idea what "offer" they are going to make me, any suggestions as to what I replace it with?

Thanks

Problems with Panasonic DMR-E85H

ok, I received the part today and attempted the repair myself.

Unfortunately, despite my best efforts, the repair did not work and the machine is now completely dead.

So after removing the hard drive for a spare, it will be going to the tip tomorrow.

I don't think Panasonic deserve my custom, so I'm thinking the replacement will most likely be a Pioneer.

Problems with Panasonic DMR-E85H

Hi Jules...sorry that the repair didn't work. LeslieRushForth's posting also mentioned replacing 2 diodes if replacing the STRG6353 didn't work. On the other hand, if the unit is now completely DEAD perhaps you could check for breaks in continuity in the 5 solder joins with a multimeter (You can also check for "unwanted" solder joins between the legs). Another (very remote) possibility is that the PSU board is a "double sided" board that needs the STRG6353 to be soldered to components on both sides of the board (not just to the "under" side).

I just received my STRG6353 chip this morning and it looks like a typical "voltage regulator chip" that you might find in lots of "build it yourself" electronic kits. This part is definitely NOT a Surface Mounted Component, ie. it's not tiny, it doesn't mount on metal pads and I wouldn't bother with low melting point solder. As far as I can tell, I would just solder it like an normal IC.

Thanks for the advice, but I've checked my solder joints very carefully.... I just think I must have damaged it in the process.

Is that good or bad?

I hope its good, 'cos I have actually bought a Pioneer DVR-440.
It was much cheaper than the Panasonic EX75 (I don't need HDMI) and so far I'm impressed by it.
The best thing is that you it can record in 'manual' mode (think FR mode on the Panasonics) to the HD without it stopping at 4GB.... one of my biggest gripes with Panasonic.
This means you work out how long a program is after editing out the adverts and use a recording mode that uses all the space on a blank DVD-R.

Jules

Problems with Panasonic DMR-E85H

My main machine is a Pioneer DVR-530H and it's great because you can do "other tasks" while a program is being recorded or is scheduled for recording...something that the DMR-E85H won't do when it's in "Timer Record" mode. My main gripe with the Pioneer machine is that the discs that it creates won't automatically start at their menu screen after loading which sometimes confuses other people to whom I send my discs (I have to ask them to press "MENU" or "PLAY" after loading the disc). It's a pity that Pioneer is losing money on their DVD recorders because they win all sorts of Design Awards. The main reason I bought my Panasonic DMR-E85H was because it was significantly cheaper than the Pioneer counterpart at that time and a lot of people I know have them. (Also, here in Australia, the Panasonic DMRE85Hs are "Made in Japan" which usually means that the quality control is better whereas the Pioneer machines are "Made and Assembled in China".)

Oh, as an alternative to sending your Panasonic to the rubbish tip, I think one of the previous posters was interested in "dead" Panasonics. Also, I sometimes see people selling "dead" electronic equipment on Ebay (sold "as is").

Thanks also to Royold and Annie_M for their suggestion of first chopping off the old STRG6353's legs with a cutter before removing the remaining "bits" and the old solder. It's a good idea.

Problems with Panasonic DMR-E85H

Hi Jules. Something else to watch out for. If for any reason your Harddrive wasn't connected properly (eg. if the power cable or the Data Interface cable were plugged in the wrong way) or if the cable between the PSU board and the MainBoard wasn't connected properly then perhaps this may stop the recorder from "powering on".

Where on earth did you get this interesting piece of information from? (if you don't mind me asking)

I've said in the past that I assume the difference between high-speed-dubbable and non-high-speed-dubbable recordings must be some sort of non compliance with the DVD standard (in the latter case), but I didn't know exactly what because there only seems to be limited information about the DVD standard available on the net, some of which seems to have been gleaned by a sort of reverse engineering process.
Hi Maldonian

There used to be info in computer/electronics magazines and on the internet about the differences between the DVD-R and the DVD+R recording methods particularly in relation to "frame accurate" editing. At the moment I can't find anything on the internet that specifically describes how DVD-R and DVD+R formats are converted into DVD-Video format but a starting point might be

http://www.dvddemystified.com/dvdfaq.html

"Non High Speed" Dubbing involves "recoding" the data. Is this what you mean by "non compliance to the DVD standard" ? (ie. the "recoding" process converts a non-compliant file into a compliant file).

DVD-R is an older system than DVD+R and I'm sure I read somewhere (in Phillips propaganda ?) that DVD-R is "BLOCK based" whereas DVD+R doesn't record data in BLOCKs and therefore is potentially a more Space Efficient system. Anyway, I was reminded about the relationship between DVD-R, Blocks and High-Speed Dubbing by a discussion on another Forum on the problem of DVD-R recorders implementing "frame accurate editing" with High-Speeding DUBBing. The Pioneer approach is to get users to choose between Frame Accurate Editing and High Speed DUBBING when they edit a program [ You either i) edit a program at the frame level but lose the ability to make a High-Speed copy of it OR ii) edit a program in "Video mod 5A8 e Compatible" mode which shifts the Chapter points up/down to the nearest BLOCK boundary (the shifting is usually only 2 or 3 frames) and allows you to High-Speed DUB it ]. On the other Hand, Panasonic decided to implement "High Speed compatible mode" recording as an option and so editing a Program is always "Frame Accurate" regardless of whether you edit a "High Speed compatible" program or a "non High Speed compatible" program.

Basically, yes. I assumed that when the high speed option is off, recordings are non compliant in some way (and therefore have to be re-encoded to make them compliant). But I didn't know how they were non-compliant, so your explanation is interesting. Of course I can't help wondering why Panasonic provide the option to make them non-compliant, there doesn't seem to be any obvious quality improvement. Apart from certain options like VBR, the only significant difference is the widescreen flagging, and I can't see why they don't flag the high speed recordings (and dubs) correctly.

But I'm wandering away from the thread's topic. Thanks for the additional information Gary, I'll have to explore what Philips and Pioneer say in their literature, and apologies to everyone else for briefly going off topic.

Hal_Loe - the DVD-RAM high speed copy always failed right at the end. In fact what happens supports the suppostion about block transfer, because it was only the very last few minutes of a recording that got lost.
I don't think it's the drive but the box is so flaky now I can't test it any further. I'm plucking up courage to get the power chip replaced.

Problems with Panasonic DMR-E85H

Me too - I've got similar symptoms: Paid 550 GBP about 18 months ago and whilst really pleased with the picture & facilities, my DMR-E85H got into a self check habit.

Seems to be whenever it has to "spin up" either HDD or DVD (power on, load DVD, dub, wake from HDD sleep, etc.) it goes off into self check, sometimes (literally) for days. I've given up using it to play DVD's and when it has started working, I've taken to permanent leaving it in "record" or play (to stop the HDD sleeping ever.)

A nice lady a Panasonic assured me this isn't indicative of the quality of their products and offered to consider the cost of repair even outside warranty (as she said,"Panasonic adopt a very flexible approach to the terms of the guarantee and often consider requests for assistance outside of that period") and suggested I get it repaired and send the the bill to "consider."

However, most repairers are going to charge 100 GBP just to take a look, and more to effect the actual repair I'm worried about a big bill if Panny don't want to pay up.

So, given that analogue TV switch off isn't far away, I'm going to cut my losses and replace with a new unit: THinking about DMR-EX77EB-K which writes most disc formats, has a Freeview tuner and is black which matches the rest of my hi-fi.

I've found a UK Internet based company company knocking out DMR-EX77EB-K for a shade over 260 GBP so it's a no brainer really.

Of course, the question is should I trust Panasonic again?

I know what you mean - my DMR-E100H cost me ?800 when new and it went pear shaped a couple of months ago.
It was outside the warranty period but I have breakdown insurance for electrical items.
It went away to be looked at and the company quoted over ?700 for a new hard drive and mentioned something about a problem with the the laser.
The insurance Co have offered a replacement but as the new range of Pannies are not available yet we decided to wait a bit - the bloke also said that as the hard drives are all bigger than 80gb in the new models then we would have to pay to upgrade the size

the question is should you trust any company who makes DVD-R's....

most people didnt buy VCR's in the early days, they rented them....why? simple, it wasnt that expensive and they got repaired/replaced free if they broke.....

and they broke, quite often....

DVD-R's are just the optical version and i'm not surprised a lot of them break down given they are made to a cost.....the brand name doesnt matter.....if you get a unit with faults then its going to happen.......obviously dirt cheap ones you expect to definitely give up within a couple years, and you'd imagine big name models to last a long time, but they are not amplifiers, there is so much more to go wrong...and it will.....

Okay here's my E85 problem, mirrors some of other people's.

1. machine turns itself off to standby without intervention

2. will not always switch back on, merely goes to checking, then back to standby, however, after a few goes it generally works for a while

3. machine records okay via timer recording, but will not dub to -RAM or -R, just turns itself off

4. I've tried a disc re-format and it makes no difference

Is the problem power supply, HDD or DVD drive related? How much and where to get it fixed?

Hi all,

Yes finally got the dreaded 'self check' after purchasing the unit when it first came into the UK (a few years ago now) - unit has been faultless otherwise tbh. Wanted to fix it to make it last a few more years until Analogue is turned off

Anyway - I have created a pictorial tutorial using the info that 'LeslieRushforth' provided (much..) earlier in this thread - it gives detailed pics on how to fix it.

the DMR-E85H selfcheck loop problem .

My 2 + year old machine failed as expected.
I bought the IC chip & got it replaced professionally for ?10.
Having removed & replaced the motherboard myself with no 3890 problems at all.
The machine works perfectly again & I ensure that it does not get too hot.
I intend to follow the advice of a previous poster & buy a spare chip as a contingency.
I will be VERY careful before buying another Panasonic item.

A big thank you to Leslie rushforth & rbjtech for the PSU STR-G6353 IC replacement tutorial and to all you others that have commented on the thread.
As you can guess by now I too am an owner of a Panasonic DVD recorder that would not get past the hard drive self test, and was completely un-responsive to all button controls. The only thing to break the continual self testing looping was to pull the power lead.
I was not well pleased as although the machine, a DMR-E95H, was a couple of years old, it had fairly limited use. I phoned a couple of repairs outlets that wanted silly money just to look at it so I carried out a search on the web and found this thread, ordered the part & fitted it today and voila the machine sails thro the self test a ok.

So, once again thanks for the advice and guide fellas

Thanks for all the information, guys.

My E85 went cookie about 18 months ago now, and I finally got around to fixing it in October '07!

Having read your advice, I decided to remove the power board and I took it to the local Panasonic dealer. I spoke to a technician and had him replace the voltage regulator chip, at the cost of ?25. Although I have a soldering iron, the surface mounted components close by put me off.

He did say that the ic failure can sometimes cause problems with the DVD drive. In my case, it seemed to be okay.

Thanks again!

Hi Craig. Yes, I too felt it was a good idea to do something about the underlying problem, ie. the long term overheating, & mounted extra heatsinks and moved the whole thing nearer to the fan. Good luck with the repair.

Welcome to the forum.

I'm pleased to hear of your success

Probably more critical than value in this location is the thermal rating of the capacitors. Use 105? Type.

Standard 85? may have a short service life in this application.

Problems with Panasonic DMR-E85H

Well after nigh on four years and having gone through the life-saving operation described previously, I now have a new problem - it won't record to DVD.

At first I thought it was just beeing fussy with 16x discs, but I've now tried it with loads and loads of different types and come to the conclusion that the machine just isn't working.

Fortunately I WAS able to retrieve some vital stuff I had on the hard drive through the following process:

1. Set it to dub to disc (high speed). It starts dubbing, but doesn't get past 0%, then says "Bye".

2. It powers up again after a few minutes, gives a message on screen, something along the lines of "There was a problem, press Enter". When you pres Enter it goes "Bye" again.

3. It powers up again after a few minutes. No on screen message this time. Go to dubbing, and try again. This time it works, but ONLY with some Datawrite Mach 4 blanks, doesn't work with any other brand/type. In fact, I tried with another spindle of the same Mach 4 discs which were seemingly identical, but they didn't work either.

So it looks like the DVD recorder element of my E85 is knackered. I'll keep using the HD part until it breaks, then probably go to Sky+. I was planning on archiving a load of VHS, but I'll probably get something which will accept phono inputs into my PC instead of buying a new standalone DVD recorder.

Yup. When I read your initial post about your machine being fussy with disks, I thought it might be the RAM drive. My EH50 went the same way after 6 months. I thought it was just very fussy until it died completely. Got it fixed under warrantee and it's never refused a disk since.

This thread is about the E85, not the EX85. The E55/85/95 range was in the shops around 3 years ago.

Anyway, you are not alone. See here.

Unlike in earlier Pannys, the firmware is installed on the HDD in the EX series. If the HDD is replaced, the machine displays 'HDD ERR' when it's powered up, and opens the disc tray automatically. A firmware update CD has to be inserted so the firmware can be installed on the new HDD.

If the HDD wasn't replaced just before the 'HDD ERR' message started appearing, then perhaps the firmware on the HDD has been corrupted somehow. And since it has happened before and the HDD was replaced, it suggests that something other than the HDD is causing it. I suggest you contact Panasonic and point out that it has happened twice, the first time within their 12 month warranty. Say that this indicates there is an underlying fault in your machine that has been there all along. Regardless of the warranty you have up to 6 years to make a claim against the retailer under the Sale of Goods Act (Google 'sale of goods act 6 years' without the quotes to find out more).

I have two E85s, both about 3 years old. One started failing about a year ago, I replaced the STR-G6353 and it's been fine since. The other one hasn't shown any sign of the fault so far. I don't know if it's significant, but the one that had the fault was made in Japan, the other was made in Germany.

I've read that XBoxes are plagued with faults. Apparently, according to a German computer mag, the wrong type of lead free solder was used and it slowly goes brittle and cracks when it's exposed to long term heat, causing failures after just a year or two. Sounds familiar. I wonder if our Pannys have the same problem. It seems plausable. I've always thought it strange that the regulator fails slowly, semiconductors normally fail suddenly. Has anyone tried remaking the STR-G6353's joints with fresh solder, after removing the old solder, instead of replacing the device?

That factor is very interesting, Maldonian.

It would be useful if those who have had to make the replacement could check on where there unit was manufactured and report it here.


I second your suggestion that satdoc should contact Panasonic on this issue.

They are likely to be sympathetic and helpful.

IC part arrived yesterday - took the board out this afternoon and took it down to a a local electrician (classic old shop with half repaired TVs scattered all over the place) to solder the bit on and 10 or so mins later all done for ?4.40 (should have been ?5 but didn't have right change in my pocket!). 10 more minutes back home to put the board back and the machine back together and job done. Total cost ?17.70

Just tested it and all is well. A VERY BIG thanks to those who have provided the pictorial guide, a very valuable piece of community spirit

The board is slightly different in the DMR-E95H but the IC part is the same. The circular item next to the IC part is bigger in the E95 and it obscures the screw that holds it onto the heat sink, so that had to come off the board as well.

Thanks again

I'll second what Mike says.

My Sanken part arrived this week and I soldered it to the circuit board tonight. It wasn't the tidiest bit of soldering you'll see and I had a spare screw left over after I'd put the E85 back together, but...

IT'S FIXED!!!

A very big thank you to the guys who identified the problem and created the pictorial guide.

Eureka!

I've fixed mine by following the steps shown.

I got the chip from signalsuk.com for about ?12 including postage.

A bit fiddly soldering (and de-soldering the old one out) but job done.

The pcb isn't straightforward to get back in. It has to seat under a pressed spike at the back as well as getting the multi-pin spring connector over it at the other side.

Thank you greatly.

Problems with Panasonic DMR-E85H

Just to weigh in with more confirmation.

My E85 is exactly 3 years old. It failed to see blank -Rs within 4 months - randomly. Panny stock. but cheap white ones. Got Panny to repair under warranty - they said they replaced the DVD drive and PSU. Of course I had no idea about this thread at that time. Only used Panny gold stock ever since.

Was so impressed I bought my mum one - hers is now exactly 2 years old. A couple of weeks ago she told me it was taking 15 mins to power up - spending all that time self checking. Before I had chance to tell her I'd found this thread she called to say she'd had it repaired at a Panny repairer. Cost ?100 but sounds like they replaced entire PSU plus a couple of minor parts (could be diodes? I'm waiting to see the invoice). What made me laugh was, they first wanted a ?35 inspection fee (refunded against repair). I told her I was glad she got the inspection fee back as I bet the repairer knew the fault the moment he saw the model number! :-) I may persuade her to write a letter to Panny getting some repair cost refunded.

Mine worked fine since the warranty repair except for one blip a year or so ago - contacted Panny who gave me the 'out of warranty but if you take it to a repairer we'll see' line. Lost the will to live with the prospect of losing machine for several days and threat of HDD being wiped and no guarantee they would not charge me a fortune, so I persevered (unplug from mains and replug fixed it) and no problems since...until

... guess what - two days mine refused to complete dubbing to a DVD-RAM (three times, three discs) and with an unfinalised DVD-R, it refused to name disk, finalise, or anything else.

So maybe one day I'll have to take the repair route this thread helpfully describes (well done everyone) but it is all ok now as I powered off and on again - seems to fix it every time - was the same with the original problem I had under warranty.

So if I keep it unplugged overnight from now on, maybe it will get me to the digital switchover. Let's hope so.

My DMR-E85H has just had EXACTLY the same problem, with a constantly looping "Self Check", and I have had to have the same voltage regulator and 2 diodes replaced. As soon as I called the Panasonic dealer about the problem, he knew exactly what the problem was.

I had the same repeated 'self check' restart problem on a e85h. Replaced the voltage regulator str g6353 as per this thread and bingo, it's a good as new now.

Thanks to everyone who's helped to post the details of how to fix it here, and especially to the pictorial guide.

One question, has anyone done a mod for additional fan or heatsink to stop this happening again? Would prefer it to be pretty and/or not noisy 24/7... Was thinking about a small fan at the side running off the hdd power supply. Anyone think it's worthwhile?

After over 2 years my DMRE85H also developed the annoying switching off and going into long reapted self check routine when asking for any command once in sleep mode. This also stopped it Dubbing from HDD to DVD.

From the information in the forum I got a replacement IC for the power supply PCB and after replacement it now all works fine again. I am an experierenced Electronics Engineer and comfortable with the delicate soldering required, I cannot recommend the IC replacement to people who are not experiernced in PCB soldering. I damaged one track pad and had to repair with wire.

I also tried to upgrade the firmware as per an earlier forum entry but the disk with the firmware file on it was not recognised.

While cutting off the legs of the old IC (to make it easier to remove) I partially damaged (outer coating) the resistor R003 that sits in front of the IC, it measures around 0.5 ohm

Even though it appears to be OK if anybody who has the service manual can advise the full component details of resistor R003, I would be very grateful.

Panasonic had to send me out 2 or 3 firmware discs before I received one that worked.

I have a different model (the Australian version with suffix HGN) to the one you have in the UK (suffix model HEB). Anyway for what it's worth, my Service Manual says that R003 is a 0.47 ohm 1 W resistor...so I'm just confirming JayCee's post.

Well my Panasonic DMRE95 has just started the self checking fault. THough it started whenever i tried to do anything after it had gone into HD sleep, now it no longer goes into HD sleep anymore and i'm a little worried about overheating.

Though it no longer goes into sleep mode it still does an extended self check and turns itself on and off if i open the DVD drive once it's in HD mode.

Annoying, but it's nice to know that it's a known problem and given it's still got 8 months on it's 3 yr warranty from Richer Sounds i think i'll take it back.

Great support from this site thanks all.

I have a 95 it worked for a year light duties then started to fail in restart through the continual self check process plagued it for 6 months i stopped trying then I found this help and did the str chip replacement worked fine for 6 weeks.

some heavy work cant recall hearing the fan cut in though and this week it slipped back into the self check and a lot BYE messages coming up! So I replced the STR chip again as i thought solved the issue last time.

Seemed logical maybe the new chip had failed !

I pin tested all the connections and all good. Restarted the unit and no result, it is stuck back in perpetual self check with an occassional letter box screen saying check or change the disk.

Any ideas greatly appreciated if not I will break this unit for spare parts and buy a new item NOT PANASONIC a loyal buyer like me for 20 years no more. After this product has failed so badly .

This site has reviewed the product to price and poor spec for components sounds like panny have to compete with amstrad or fidelity.

Thanks

Dino7

Problems with Panasonic DMR-E85H

If the fan is bust and the chip is not receiving adequate cooling then the STR chip is bound to fail again.

It could be a hard disk failure also if you are receiving messages to that effect. Try swapping the disk. Most, if not all, the postings in this thread quote the "self check" problem as the failure cause. I don't think any of them mention disk failure messages.

My E85H is around three years old now and has never failed. Only fault has been a stuck disk which I removed. It's very well ventilated and only gets moderate use as I have seven other Panny recorders.

Presumably the E95 also has one or two electrolytic reservoir capacitors on or near the PSU board. This type of capacitor is also prone to failure. These have been mentioned in this thread previously.

Re: Dino7's problem. SELF CHECKING can also be caused by a faulty disc. If you happen to have a disc stuck in your machine, you'll need to get it out. Other than the things that Royold mentioned, it could also be the disc reading/recording mechanism at fault (eg the laser may be faulty).

It's difficult to know how widespread this fault is. The American movie fan forums that I visit generally recommend their Panasonic DVD recorders to other members however their machines probably use a different power chip to the UK/Aus/NZ machines. Also, not everyone with a UK/Aus/NZ Panasonic DMR-E85H machine has the SELF-CHECK problem (eg. Royold and a few people I know)

The other problem is that Panasonic (as well as the other manufacturers) think that most of their customers want to replace their machines with a newer model after 2 or 3 years. I still have my old DMR-E50 machine. It works but I hardly ever use it (except when my DMR-E85H wasn't working !) mainly because it doesn't have a Harddrive.

Mine developed this fault about 2 years after I purchase and the machine had very little use mainly recording to the hard drive. It finally died on me.

Reading the forums I decided to do the repair it myself
The problem is that it as a poorly designed PSU (power supply) NOT COOLING THE VOLTAGE REGULATOR…….IC part No. STRG6353 made by SANKEN ELECTRONICS in China .This is marked on the PCB board IC 001.
THE PART IC STR-G6353 CAN BE PURCHASED AT NIKKO ELECTRONICS FOR AROUND ?5 EACH I bought 2 one for a spare over the internet with next day delivery………………………www.nikkoe.com

THE REPAIR
1. DOING THIS IS ENTIRELY YOUR OWN RISK AND I WILL NOT BE HELD RESPONABLE FOR ANY DAMAGE OR INJURIES INCURED.
2. DISCONECT ALL MAINS POWER AND REMOVE MOULDED TWO PIN PLUG FROM RECORDER.
3. Remove top cover….one large silver screw at each side…..three small black screws on the back.
4. Remove the hard drive top retaining metal cover which as the black ribbon cable also attached to it then pull out the ribbon cable from the hard drive CAREFULLY then also pull out the power connection plug to the hard drive remove hard drive
5. You will see that there is a plastic rubber moulded insulator to reduce vibration from the hard drive….remove this.
6. Remove the bottom hard drive retaining plate (four screws) to get access to the power supply PCB board.
7. Removing the PSU board (card)….Remove the small black screw where the mains elec 3E38 tric enters the machine then lift off the multi jumper that conects to the main board pull and gently tilt towards you.
This should take an average twenty minutes at most to get the card out.
8. I took the card and the IC to a local T.V repair shop who took just five minutes to replace WHICH I RECOMMEND BECAUSE THE CARD IS DOUBLE SIDED WITH VERY SMALL SURFACE MOUNTED COMPONENTS WHICH CAN BE DESTROYED VERY EASILY.They charged me ?5
9. RE-ASSEMBLE

Worked fine for me without having to replace any more components.

Hope this helps without getting ripped off for the repair.
Just to confirm - this works!!! Just picked up the power supply card from my friendly local electrician who fitted the part for me for the huge total of ?4.

I nervously put it back into my machine - had a quick scare when I thought it had stopped working entirely... turned out that I hadn't actually put the plug in!

Anyway, it's seemingly working like a dream now - currently dubbing something to DVD that I've been dying to do for a few weeks.

Very, very happy - many thanks Leslie!

THE PART IC STR-G6353 ...is this a voltage regulator? then as lesie said, just to confirm i read it right?


great news


Would a local electrical shop have access to the part?, and charge a small sum to fit it, or will it be cheaper as above poster said, to just take it apart, and take only the affected card in to have the new part fitted.

raigraphixs

Problems with Panasonic DMR-E85H

95% of the problems with the panasonic DMR E85H are caused by the voltage regulator marked (IC 001) on the PSU (power supply board)...part no STR-G6353 which gradualy starts to fail then dies this is caused by lack of cooling.
The IC part No STR-G6353 is made by SANKEN CORPORATION in China and sells for around ?5 here in the U.K. read my previous post where to buy or search the NET
By replacing this IC should solve the problem .......IF this does not solve the problem then two more components nead to be replaced on PSU board which are.......
ZD002 = MA4068N
ZD004 = MA80510ML
These are diodes...... REMEMBER THE CORECT POLARITY WHEN REPLACING

WARNING....WARNING.....DO NOT ATTEMPT TO SOLDER THE COMPONENTS INTO THE BOARD UNLESS YOU HAVE CORRECT SOLDERING TACKLE AND HAVE EXPERIENCE WITH SURFACE MOUNTED COMPONENTS....BE WARNED...........
TAKE THE BOARD OUT AND TAKE IT GOOD T.V REPAIR SHOP.Should not cost more than ?5 five minute job.

Other than that take it to Panasonic repair center and get shafted big style........You will nead a morgage.

Excellent information on the DMR-E85H PSU. If the diodes are marked ZD then they are zener diodes (special voltage regulating diodes) and there is some info on how they work listed :

http://web.acc.qcc.cuny.edu/nsfrobot/zenerbhv.htm

So far no PSU problems with my E85H and its well over two years old now. Doesn't get too hot tho' as I switch off at the mains when not in use. Nevertheless, Les, I have filed away your info on this PSU. Many thanks.

Problems with Panasonic DMR-E85H

I get the impression Panasonic knew the power supply got too hot.

With my DMR-E95H unit I received a separate page warning to keep the recorder in a well ventilated space and not to mount the unit above a VCR.

With my dads 60D there is no such warning or requirement for not mounting it above a VCR...

So I intend to relocate my unit when I have repaired it.

I was think that, is the problem going to crop up on current Panny models???, my previous one was in a small cabinet, with no back for venting. Maybe it needed more space.

raigraphixs

Problems with Panasonic DMR-E85H

Well....following my previous posting, I phoned Panasonic who said that they might assist if I took it to their approved service centre.

I wish I had read the posts on this page first. The fault was traced to the power regulator, and Panasonic paid for the parts. But the labour cost was the MINIMUM £65/hour +VAT. Just to add to my woes, the hard drive had to be formatted, I was told, therefore losing recordings that I had not had time to put onto DVD.

This is the 4th time in two years that the machine has been in for repair.

I wonder if anyone from Panasonic reads these forums?

Problems with Panasonic DMR-E85H

My E85H has only ever had one fault in well over two years and that was a stuck disk. My set is kept on an open shelf and has plenty of room at the rear for the fan to disperse the heat. It is also always switched off at the mains when not in use. This is the reason I believe I have never had a PSU fault.
Ventilation is the key feature. Do not keep them in an enclosed cabinet.

I think the whole point is that they obviously made a DVD Recorder that couldn't be treated the same way as existing exquipment, it is a step backwards. Which is probably why the range was quickly replaced...

A main brand like Panasonic should have more durabilty than this.

My Technics CD Player which is coming up to 20 years old is still working and has only had one minor repair I did myself (just a dry joint on one of the output phono sockets).

Ah, but your CD player doesn't have a hard drive. Hard drives get extremely hot in use - check the one in your PC if you don't believe this. Coupled with that - if the PSU is close to the HDD then its essential that the airflow from the fan isn't restricted in any way.

The Digifusion PVR's also seem to have problems with heat unless well ventilated. Even the largest fan isn't of much use if the same air keeps being recycled. It just keeps rising in temperature.

True but this isn't the first DVD Recorder with hard drive that Panasonic have made, but it appears to be the first one to be affected by these PSU over heating problems.

The IC part No STR-G6353 is made by SANKEN CORPORATION in China and sells for around ?5 here in the U.K. read my previous post where to buy or search the NET
By replacing this IC should solve the problem .......IF this does not solve the problem then two more components nead to be replaced on PSU board which are.......
ZD002 = MA4068N
ZD004 = MA80510ML
These are diodes...... REMEMBER THE CORECT POLARITY WHEN REPLACING

WARNING....WARNING.....DO NOT ATTEMPT TO SOLDER THE COMPONENTS INTO THE BOARD UNLESS YOU HAVE CORRECT SOLDERING TACKLE AND HAVE EXPERIENCE WITH SURFACE MOUNTED COMPONENTS....BE WARNED...........
TAKE THE BOARD OUT AND TAKE IT GOOD T.V REPAIR SHOP.Should not cost more than ?5 five minute job.

Other than that take it to Panasonic repair center and get shafted big style........You will nead a morgage.


Les .....Chesterfield U.K.
took my card over to local tv shop hoping for a ?5 solder jobbie,....how much...?17.50 , management rule. . I said no.
A guy at work said he do it and he wouldnt charge. Didnt really want to ask him, but tv shop is taking the biscuit.

I sent an email to Panasonic Customer Care, with a link to this forum, pointing out that the power regulator failure seems to be happening to a few customers. This was the response:

"In response, as stated in our previous correspondence, this failure is not indicative of poor quality. Whilst Panasonic products are manufactured to the highest specifications, there is always some potential, as with any electrical appliance, for some component failure to occur over a period of time and use.

I would also stress that there is not an inherent defect with this model."

They would not say that anyone would read this thread.

So,

Bought two of the today for $8.80 in Australia.

But, supplied STR-G6653 instead of the STR-G6352.

Has anyone tried this instead? They certainly look similar if you compare the data sheets from their competitor (http://www.chtechnology.com/pdfs/isc.../irisg6653.pdf and http://www.chtechnology.com/pdfs/isc.../irisg6353.pdf)

Please note: if you replace the regulator, you will more than likely fix the problem - for now, but unless the ventilation is improved, or a better method of cooling is adpoted, I strongly suspect it'll happen again!!

Agreed - I've done two things to improve things -

1) I have cut out the entire section of case behind the fan (rather than the small slits they cut out as stock) - thus allowing extra airflow.

2) I have added extra heatsinks to the totally insufficient stock heatsink. Unfortunately, there are no direct bolt on replacements for this - so I had to bolt on extra heatsinks cut from Aluminium plate using the extra holes in the stock heatsink. You have to temporarily remove the large capacitor to get to the right hand hole to do up the screw.

I didn't bother putting this in the tutorial as I hoped another 2 years use before needing to do it again is acceptable (if analogue is not switched off before then

If people want to see the extra heatsinks - then shout and I'll add it to the tutorial as an 'optional' section.

I too am having "self-check" issues with the E85, BUT, only with DVDs (most, but not all of them) and it doesn't happen with CDs!

Has anyone else seen a similar behaviour?

I wonder if this is just the first step on the journey to replacing the STR-G6353.

When playing CD's, a different laser [ co-mounted] is used which is probably less demanding of the power supply system so does not overtax it ... hence no symptom.

Problems with Panasonic DMR-E85H

I too developed the now famous "self check" fault with my DMR-E85H. The unit would take almost 30 seconds to load at start up whilst going through the self check routine. I also found that whilst dubbing large files to DVD-RAM the unit would stall and the display would go blank. It would then reset itself and begin to reboot (another 20-30 seconds). It would even sometimes reboot itself three or four times continuously one after the other. The unit would also decide to reboot at any time whilst watching TV or whenever I ejected/inserted a disk.
I became fed up of the performance of my unit and decided to take the advice mentioned above and ordered myself the STR-G6353 part. I then followed the instructions laid out by RBJTech and removed the PSU board from the unit. I soldered the new part as instructed and put the unit back together carefully, remembering where each part went.
I then powered the unit back up after re-assembling and the "self check" fault had gone!!!!!!
My unit now responds faster and I can dub all files. The unit does not reboot ever now and I am very happy. Thanks to RBJTech for his detailed guide!

Heya again.. Just thought I'd pop by and see how things are developing. It would appear that Pan-The-Sonic are still adopting the ostrich approach to this problem. Isn't it good to know that there are people with brains in their head in this world!

Now, for everyone who's doing this home brewed repair...

Please note: if you replace the regulator, you will more than likely fix the problem - for now, but unless the ventilation is improved, or a better method of cooling is adpoted, I strongly suspect it'll happen again!!

They even produced a screwdriver and dismantled it so I could retrieve a CD which was stuck inside. Full marks to them for service.
My E95H has worked perfectly since.

I believe it has the same PSU, so don't hold your breath Same fix though, so all is not lost.

Hi Picapete. If you have firmware recording problems with 8x and 16x discs then you would have experienced these in 2005, not in 2007. When my machine had problems recording more than a single program onto 8x discs in 2005 I was sent a firmware upgrade disc by Panasonic Australia (the disc upgraded my machine's firmware up to 18th April 2005.....nb. they sent me several discs before I received one that actually did something). Since the upgrade I haven't had any problems with 8x or 16x discs (touch wood).

However, the SELF CHECKING problem is more likely a POWER Supply problem although there could be something wrong with your DVD RAM drive that causes a Power drain.
