Swapping Panasonic DVD Drives Compatibility Considerations

Panasonic DVD drives may not be swapped across different model year production.

The 2005 DVD drive VXY1867 with the large black plastic case has three ribbon cables connected to an onboard pcb controller and from that pcb there is a single ribbon cable to the separate Digital PCB.

The 2006 models use DVD drives VXY1916, VXY1945 or VXY1972 with their four ribbon cables connected directly to the separate Digital PCB.

The 2007 models use DVD drive VXY1961 with the four ribbon cables connected to the onboard pcb controller and and from that pcb there is a single ribbon cable connected to the separate Digital PCB.

The 2008 models use DVD drive VXY2010 with the four ribbon cables connected to the onboard pcb controller and from that pcb there is a single ribbon cable connected to the separate Digital PCB.

These DVD drives may not be interchanged from one model year to another.

Panasonic’s 2006 model year DVD drives are powered through a ribbon cable instead of a wired connection as found on 2005, 2007 and 2008 model year DVD drives.

The 2006 DVD drives I’ve examined are paired with the Digital PCB VEP79132. That printed circuit board stores the DVD drive alignment data, including error codes/history, accumulated "working time," even the "laser used time (hours)," of the DVD drive with which it has been paired.

Panasonic repeatedly cautions that 2006 model DVD drives and the separate Digital PCB must be replaced together as a “module,” and if not replaced together, the "module" requires "realignment" as the DVD drive alignment data is stored on the Digital PCB.

As mentioned in earlier posts I have successfully swapped 2006 model year DVD drives between different 2006 DVD recorder models. So far I’ve retained a machine’s original Digital PCB whenever swapping DVD drives. One such 2006 DVD drive, pulled from a DMR-ES35V parts machine, subsequently gave nine months’ satisfactory service in a DMR-ES15 until that DVD drive’s laser assembly failed. Another 2006 DVD drive, originally from another DMR-ES35V parts machine, was swapped in. That DMR-ES15 continues in daily use.

Panasonic's 2005, 2007 and 2008 DVD drives have onboard circuit boards that store the drive alignment data so the separate Digital PCB does not need to be paired with a specific DVD drive. While 2007 and 2008 DVD drives have a similar appearance these DVD drives have different model numbers. It is presumed that 2007 and 2008 drives may not be interchanged across these two model years.

The several posts that follow have attached photos showing a 2005 DVD drive and its onboard PCB; two models of 2006 DVD drives and the separate Digital PCB; a 2007 DVD drive, its onboard PCB and the separate Digital PCB; and a 2008 DVD drive, its onboard PCB and the separate Digital PCB. Notice the variations in ribbon cable arrangement between the various model years and the wired power connection utilized with 2005, 2007 and 2008 model year DVD drives.

The attached photos are from the 2006 model year. The first photo shows the VXY1972 DVD drive in a DMR-ES35V. The second photo shows a 2006 DVD drive and the ribbon cable connections to the Digital PCB VEP79132. The third photo shows a VXY1916 DVD drive originally installed in a DMR-ES35V, notice the circled "35." The fourth photo shows this VXY1916 DVD drive installed and functional next to the Digital PCB VEP79132 in a DMR-ES15.

The 2006 Service Manuals (DMR-ES15 at page 16, DMR-ES35V at page 20, DMR-ES45V/46V at page 23) indicate that the Disc Maker ID may be displayed in Service Mode. Perhaps 2006 Panasonic DVD drives VXY1916, VXY1945 and VXY1972 are produced by different manufacturers.

Some 2006 model year DVD drives do not have the model number stamped on the top of the drive lid.

Some nice information. You must be making use of your "service manuals"
Thanks for sharing.

Recently I’ve been snapping new photos and reorganizing/renaming older photos. I’ve also consulted a few Panasonic Service Manuals, sometimes an exercise in frustration when some information is so poorly translated (if it’s included at all). Some important information is not to be found in these manuals.

For instance, Panasonic cautions that 2006 model year DVD drives and Digital PCBs must be replaced together as a “module.” If DVD drives and Digital PCBs are not replaced together (according to Panasonic) the "module" requires "realignment" as the Ram Drive configuration data resides on the Digital PCB. (Panasonic refers to a DVD drive as a “RAM Drive.”) In Panasonic’s 2006 model-specific DVD recorder Service Manuals there is no information about what this "realignment" entails.

There are references here and there to Ram Drive (DVD Drive) model-specific Service Manuals but I have been unable to locate these manuals. Panasonic states that “RAM Drives and Digital PCB(s)” are "impossible" to service at the component level but they may be recycled by returning them to the "Service Center." This implies that defective Digital PCBs must be swapped out with a new or known good Digital PCB that must then be “aligned” or "realigned" for use with a specific Ram (DVD) Drive. One would think that a functional Digital PCB might be “realigned” in somewhat the same manner as running a firmware update but that information is missing from 2006 model-specific DVD Recorder Service Manuals.

But what of a DVD drive with failed/defective parts? There are many parts machines with good parts that may be found in the field.

Apart from regular hub/spindle cleaning the DVD drive part that most commonly fails is the laser assembly. OEM replacement laser assemblies are available online through second parties. Mickinct has posted source information and has also reported replacing the laser assemblies in several Panasonics, including some from the 2006 model year. There are certain cautions/procedures that must be observed when handling laser emitting devices. Electronics is not my field so I have no training in that area. Perhaps Mickinct or someone else with that experience will respond with specific information or advice.

No, I'm sorry I don't. If you have a 2004 model year product perhaps you might check the model number found on the drive lid and post that information. If the drive model is VXY1867 then it would interchange with 2005 model drives.

With the 2005 DMR-ES30V model there is rubber damping built into the DVD drive mounting platform and there is additional damping around the drive mounting screws, see the second photo. There is probably damping for some earlier models as well. The stripped down late 2005 DMR-ES40V model omits the rubber damping, see the first photo. Later models also have rigid DVD drive mounting platforms such as that found in the 2006 DMR-ES35V model, see the third photo.

Then that could explain why the '05 machines are Soooo much quieter than the '06 and on machines. Really shows up when finalizing/editing and chase playing.
The '05 machines are also a fair amount heavier too. I think by '06 they started looking for ways to cut costs and build quality is usually the first thing to suffer. Not that I think their is anything wrong with the '06 ES series machines but they aren't built like a tank like the older ones.

The Digital PCB is the “brain” of a Panasonic. In the 2006 model year the Digital PCB VEP79132, unlike other model years, also serves as the DVD drive controller. Does this Digital PCB interchange between various 2006 model Panasonics? Not necessarily.

The first photo shows a VEP79132 from a DMR-ES15 at the top and a VEP79132 from a DMR-ES35V at the bottom. The pen and pencil point to two extra ribbon cable connectors found on the Digital PCB used in an ES35. These “extra” connectors accommodate ribbon cables for a hard drive and a HDMI PCB found on various other Panasonic models. See the next post for a photo of a 2006 model year DVD drive’s four ribbon cables connected to the Digital PCB.

The second photo is a closer view of the top side of a DMR-ES15 model’s Digital PCB as seen mounted on its platform. Notice the fitting for the DVI connector at the lower right.

The third photo is a close view of the bottom side of the DMR-ES15 model’s Digital PCB. Notice that the small DVI PCB, seen at the lower left, utilizes a hard connector. This DVI PCB extends beyond the platform to the ES15 model’s front panel.

The fourth photo is a closer view of the top side of the DMR-ES35V model’s Digital PCB as seen mounted on its platform. Notice the ribbon cable connection to the DVI PCB seen under the Digital PCB at the right.

The fifth photo is a close view of the bottom side of the DMR-ES35V model’s Digital PCB as seen mounted on its platform. Notice the DVI and SD Card PCB at the left. (The ES35 model does not have a SD Card slot.) This DVI PCB extends beyond the platform to the ES35 model’s front panel. Notice the DVI/SD Card ribbon cable routed to a different DVI connector found on the top side of the ES35 model’s Digital PCB, see the fourth photo. The finger is pointing at the DVI hard connector that is not used on the ES35 model.

Here is a report of my project swapping three VEP79132 Digital PCBs into my DMR-ES35V "6490" (parts machine #2) in an attempt to bring that parts machine into a functional condition. I am attaching a sampling of photos snapped before and during the third phase of that project.

1-The VEP79132 Digital PCB original to DMR-ES35V "6490" gave a momentary U61 error on the machine's display and output a pink picture with narrow but indistinct blue/black lines running top to bottom as viewed on a RCA CRT TV connected to the DMR-ES35V's "common" composite output. Behind the pink screen and vertical lines could be seen a faint error box, probably the "failed self check" message. None of the machine's front panel buttons responded after the first power on. None of the remote buttons, after the first power on, provided control of the machine.

2-A VEP79132 Digital PCB from DMR-ES15 "9739" (parts machine #3) was mounted on a DMR-ES35V Digital PCB platform and installed in DMR-ES35V "6490." With that Digital PCB in place the DMR-ES35V powered on normally and provided a good blue screen to the TV. The DMR-ES35V output transitioned to the initial setup menu(s). An antenna was attached and antenna reception was selected and an automatic channel scan was run. No channels were found. Next, a Comcast cable-ready RF feed was connected, the setup menu was changed to cable reception and the automatic channel scan was run. No channels were found. A Zenith DTT900 CECB was connected through the DMR-ES35V composite Input 1 but no programming was accessible through that input.

3-A VEP79132 Digital PCB from DMR-ES35V "4755" (parts machine #1) was swapped in. In its original DMR-ES35V this Digital PCB had given many of the same results as described in test #1 above. Installed in DMR-ES35V "6490" this Digital PCB gave a momentary U61 on the machine's display and produced a good blue picture with the "failed self check" box. The machine was responsive to the remote. Pressing ENTER caused the machine to power off. Powering up repeated the very same U61 and "failed self check" routine followed by powering off. The machine remained responsive to its own POWER button and the remote control's POWER button but was unresponsive to other front panel buttons and other remote control buttons.

Conclusions:

1-Neither DMR-ES35V parts machines' original VEP79132 Digital PCBs approached normal functionality in DMR-ES35V "6490." Both DMR-ES35V Digital PCBs utilized in this experiment are probably defective, perhaps the reason these are parts machines.

2-The DMR-ES15 VEP79132 Digital PCB approached functionality in DMR-ES35V "6490" but fell short due to possible incompatibility with a DMR-ES35V or some other unknown problem(s) present in DMR-ES35V "6490."

Additional Observations:

Photo #1 provides a side-by-side view of the original VEP79132 Digital PCB from DMR-ES35V “6490” on the left and that from DMR-ES35V “4755” on the right. Notice the extra ribbon cable connector (seen near the top just to the left of center in photo #1 and closer up in photo #3) on the “4755” Digital PCB at the right. That ribbon cable connector is not present on the “6490” Digital PCB at the left. Another ribbon cable connector (seen just above the DVI PCB ribbon cable in photo #1 and also in photo #3) is black on the "4755" and brown on the "6490" Digital PCBs. In post #12 (above) a comparison was made between the original VEP79132 Digital PCB from DMR-ES15 “9739” and that from DMR-ES35V “4755.” The first photo in that post points out differences between those versions of the VEP79132 Digital PCBs. These “extra” connectors accommodate ribbon cables for a hard drive and a HDMI PCB found on various other Panasonic models. Photo #5 shows the VEP79132 Digital PCB from DMR-ES15 "9739" that returned better (but not good enough) results when swapped into DMR-ES35V "6490." (That Digital PCB is shown two days earlier mounted on its original platform.) When attempting to "swap" a Digital PCB keep in mind that these boards come from the factory configured for the model in which they are installed. One would think that a functional Digital PCB might be reconfigured in somewhat the same manner as running a firmware update but that information is missing from model-specific DVD Recorder Service Manuals.

If I'm understanding correctly, I'd need to remove the 2010's board and connect it to the 1961. My roadblock is the ribbon cables. I've examined your photos up and down, and...I just can't see how I'm supposed to pull them off. I've noted your caution about flipping it up but... Part of the problem is my fingers are larger than I'd like...I've gently tugged at them, tried to rock it a little.
How do you manage to disconnect them from the board?

After spying the single ribbon cable going from the drive to the inside of the 48 connectede to a green board, part of me wishs this were as simple as unplugging it from there, and replacing with the other, but that would make things too easy now, wouldn't it?
Be sure to grasp the colored reinforced tabs at the end of the ribbon cables with the ribbon cable itself and pull straight out. One ribbon cable connection has a hinged lock that must be opened, as seen in the first two photos in my 2/19/2010 post, in order to remove and reinsert the ribbon cable.

Do not rock the ribbon cable as anything but a straight pull may damage the ribbon cable contacts. About the only remedy for a damaged contact strip is trimming it back just enough to provide uniform connectivity. The first two attached photos show a damaged ribbon cable contact strip before and after it was trimmed back.

The single ribbon cable at the end of the DVD Drive controller circuit board in 2007 and newer Panasonic EZ series recorders is connected to the Digital PCB. That ribbon cable, as well as the four other ribbon cables may be seen in the fifth photo attached to my 2/19/2010 post. Pay special attention to the orientation of the reinforced tab with the copper colored ribbon cable as mentioned in my 2/19/2010 post. With combo recorders the Digital PCB is mounted on the sub-platform under the DVD Drive. With DVD recorders the Digital PCB is mounted beside the DVD Drive. The Digital PCB in my DMR-EZ28 is seen in the third attached photo. The ribbon cable to/from the DVD Drive controller board is seen toward the lower left in the photo.

There is a possibility that some Digital PCB boards must be matched with the correct DVD Drive controller board. If that's the case then one might swap both those boards at the same time. In any event it would still be necessary to disconnect the four ribbon cables from the DVD Drive controller board to the sub-assemblies inside the DVD Drive. More detail is found in my 2/19/2010 post.

I did and a few minutes later the machine was up and running normally again. It reads writes and finalizes ok. So the newer drive apparently uses a compatible laser. I wanted to fix the ez-17 because I really like the 2xlp picture which they seem to have dropped on the 2008 series models.

I've revised this thread's first post to include this news for those with Panasonic EZ series recorders.

Those swapping DVD Drive controller boards should notice that the connector for the laser assembly ribbon cable has a flip-up locking/unlocking mechanism as seen in the first two photos. Also notice the ribbon cable grip-tab orientations as seen in the fifth photo. The three upper ribbon cables have their colored grip-tabs facing outward while the lower copper colored ribbon cable grip-tab faces inward. (The ribbon cable functions are, from top to bottom, 1-disc tray and slide-cam motor—narrow green grip-tab, 2-spindle motor—blue grip-tab, 3-laser assembly data cable—wide green grip-tab, 4-laser assembly transport motor--copper colored cable with inward facing dark brown grip-tab, 5-the ribbon cable seen at the lower left of the on-board PCB is the data cable connected to the Digital PCB.)

Sometimes it's necessary to read between the lines of eBay listings to weed out machines that have the same problem(s) as your EZ48.

I would ask the seller what "noises" (if any) are heard from the DVD Drive. If there is a "grinding" noise that's usually OK as it's most likely a dirty rubber hub. If there are "clunking" "chugging" or "errrp" noises that's not OK.

Back in 2007, after careful reading of DealTree listings, I bought two 2006 DMR-ES35V "as-is parts machines," one priced at $17.00 and the other at $15.29 (including shipping). One had a bad tuner, the other had a bad Digital PCB. Both had good DVD Drives, one that is still in daily service and the other that later experienced a laser assembly failure after nine months of heavy use in a DMR-ES15.

I've also responded to your earlier EZ48 thread post suggesting some options.

Yes, you can do it, but...

The complications come when it's unknown which part(s) have failed. The most common failure is the DVD Drive laser assembly. Other possible (but less likely) failures are the DVD Drive's on-board controller and the separate Digital PCB. Unless there has been a disturbance to the ribbon cables the cables are unlikely to be problematic.

If a good 2007 VXY1961 DVD Drive is located it would probably have to use the on-board controller from your VXY2010 DVD Drive. But what if your DVD Drive's on-board controller has failed? And what if your separate Digital PCB has failed? Those boards would have to be replaced with good boards from another EZ48 or EZ485. The boards from a EZ28 or any of the 2007 models might not work with your EZ48.

Most often the parts that fail are the laser assembly in the DVD Drive or the Digital PCB itself. (As seen in earlier photos the Digital PCB is mounted on the platform under the DVD Drive in Panasonic combo recorders.)

While Panasonic maintains that the DVD Drive and the Digital PCB in 2006 models must be replaced together as a "module," that is not necessarily true as has been documented in several posts in this and other threads.

Now, as to your situation, it all depends upon the condition of the parts themselves. The questions to ask are "why did the seller(s) offer DMR-ES46V models for sale?" and "what defects/failures, if any, did the seller(s) describe (or conceal)?" Since a used 2006 DMR-ES46V has likely had heavy or very heavy use (or abuse such as being closed up inside a cabinet or being stacked atop a heat producing receiver or amplifier) those might be the reason(s) that Panasonic recorders have been offered for sale. (In recent months a local seller has had his 2005 DMR-ES30V on Craig's List with a photo showing it sitting atop a high-powered amplifier, Yikes! That DMR-ES30V would be one to avoid.)

On the other hand the eBay seller(s) may have given-up on the DMR-ES46V when it/they had reading, writing or finalizing failures caused by nothing more than a dirty rubber hub in the DVD Drive. Perhaps the owner(s) would have kept the DMR-ES46V model(s) had they taken the fifteen minutes to do the routine cleaning.

If your newly-purchased DMR-ES46V models have DVD Drive(s) in good condition then swapping into your original DMR-ES46V (after the routine lens/hub/spindle cleaning) should be successful as long as your original DMR-ES46V Digital PCB is also in good condition. In any event, you now have your own parts source.

If you find it necessary to swap a Digital PCB notice that this board is secured to the platform with three screws only, even though there are four screw holes on the board and the platform. One of the platform holes is not threaded. Do not attempt to use the fourth screw position as the force required to fit a fourth screw might damage the Digital PCB. In the attached photo notice that the screw position at the lower right is not used.

The DMR-ES46V pictured in my 3/7/2010 post has an interesting history.

This DMR-ES46V was manufactured in September 2006 and originally sold for $218.99 at a Costco store in Salem Oregon. It was a gift to the owner. The owner reported that he had difficulties with this DMR-ES46V, taking it back to the Costco store in Salem. That Costco store sent it to a Portland repair shop in November 2007. That shop replaced the RFKNES46P RAM DIGITAL MODULE (DVD Drive and Digital PCB) with a new “module” (then) priced at $323.35 with a labor charge of $39.00, all of which costs were paid by Costco. (The customer receipt for this repair is in the DMR-ES46V box with the other documents.) Then, Costco returned this repaired DMR-ES46V to the owner. The owner reported that he continued to have difficulties with this DMR-ES46V so he opened it up to see if he could see anything wrong. That owner didn’t know what to make of the electronics and put this DMR-ES46V back in its box, where it was stored away and forgotten.

In April 2009, after moving to Vancouver WA, the owner listed this DMR-ES46V “as-is” on Craig’s List for $20.00. I had no hesitation paying the owner’s asking price.

Upon checking out this DMR-ES46 I found it “dead.” As I had a heavily-used DMR-ES35V that had just experienced a laser assembly failure at around 3,140 recording hours, I swapped in this DMR-ES46V model’s near-new DVD Drive, with only around 120 hours of laser use time, and the associated near-new Digital PCB. After the "module" swapping the DMR-ES35V checked out OK and it was returned to a fully-functional status. (At the moment that DMR-ES35V is a standby recorder.)

That same DMR-ES35V model’s original Digital PCB was then swapped into DMR-ES35V “6490” (a “parts machine” mentioned in posts 14, 30-34 earlier in this thread). That DMR-ES35V was also returned to a fully-functional status and it has been in daily use for several months.

The “dead” DMR-ES46V, with its swapped-in DVD Drive (that has a failed laser assembly and defective DMR-ES35V Digital PCB) remains in its original box as a “parts machine.”

Hi again I notice the spindle is not spinning it was before I took it apart, cables looks find they all face towards the vcr (pin wise) I've been reading a lot of your posts you have a lot of information thank you for that! I checked my laser # it's 3332a can that tell you what year it came out? Also would you know what laser number would be in a DMR-EZ48V? thanks

thanks I love my DMR-ES46V.

The DMR-ES46V is one of the four best VHS/DVD combo recorders that's been marketed in the US. (The four best non-hard drive combo recorders are all Panasonic products, the 2005 DMR-ES30V, the 2006 DMR-ES35V and the 2006 HDMI-equipped DMR-ES45V and DMR-ES46V models.)

Your DMR-ES46V has given you good service and will continue to give you good service if you have the experts at Panasonic's Elgin Illinois Service Center return it to new functional condition. The $130 flat-rate repair is a bargain for repairing/rebuilding this outstanding product.

If you've disassembled your DMR-EZ46V to the extent that you've observed the model number on the bottom of the laser assembly there will be several reassembly and realignment issues. See earlier posts in this thread for procedural details and photos. I've already mentioned/linked to those posts, #6 and #7; and another, #30, is found here:

http://www.avsforum.com/avs-vb/showt...5#post16480525

If necessary, follow the information provided in earlier posts 6, 7 and 30, to carefully reassemble your DMR-ES46V before sending it to Panasonic in Elgin Illinois.

Be sure to provide a written description of the problem(s) so that the Panasonic experts will resolve all the issues with your DMR-ES46V.

Do not consider exchanging your outstanding DMR-ES46V for the inferior DMR-EZ48V.

For information concerning the problematic EZ series combo recorders consult the main DMR-EZ48V thread and heed the advice found therein:

You may also find a front panel display showing U61, U88 or U99 errors with a failing or failed laser assembly or Digital PCB.

If you encounter reassembly/realignment complications due to reconnecting the power cord, powering the recorder on and opening/closing the disc tray while the DVD Drive lid was removed, see this post and the post following it for reassembly/realignment procedures:

Removing the DVD Drive lid gives enough access to the parts that require cleaning, the lens, the rubber hub and spindle area, the disc tray and the guide wheel on the underside of the DVD Drive lid.

In the first photo the pencil points at a very dirty roller/slider in the normal far left position. First, I put my finger on the top of the roller to keep it in place, then I use an air can to blow dust off the disc tray and roller/slider. Then I use a cotton swab dipped in 91% alcohol to gently roll over the lens one time only. Then I use the cotton swab to clean the rubber hub and spindle area and finish up with the guide wheel on the underside of the DVD Drive lid. The pictured DVD Drive is seen mounted in a 2006 DMR-ES25.

The second photo shows a DVD Drive lid guide wheel being cleaned. The pictured DVD Drive was one of two removed from 2007 DMR-EZ17 models for photographic documentation of tear down and reassembly procedures.

In several earlier threads I've provided information and this link to the lens and hub/spindle cleaning procedure:

http://www.avsforum.com/avs-vb/showt...8#post14479898

I've discouraged removing the DVD Drive from the machine due to the possibility of disturbing or damaging ribbon cable contact strips. A damaged ribbon cable contact strip will disrupt data transfer between the laser assembly and the Digital PCB.

The cleaning procedure itself calls for a thorough cleaning of the rubber hub and the adjacent spindle area as well as a gentle cleaning of the lens as its only loosely suspended atop the laser assembly. The laser assembly guide rods require very little grease--generally they should not be cleaned. If the rods have been cleaned take care to replace the grease with the same formulation in the same amount.

Of course, a laser assembly that's only a marginal performer will fail. "Clunking," "chugging" or "errrp" noises most often indicates a failed laser assembly. And, there is always a possibility of other types of failures, including a power supply electrolytic capacitor failure as discussed in this thread:

http://www.avsforum.com/avs-vb/showthread.php?t=1055111

The Panasonic-approved repair procedure for a 2006 model with a failed laser assembly or other DVD Drive related issues is replacement of the DVD Drive and Digital PCB as a "module." This repair, at the parts-and-labor rate, is very expensive--the parts alone for a DMR-ES46V (the RFKNES46VP RAM DIGITAL PCB MODULE) are priced at $421.69 through "authorized" repair shops or Panasonic Parts in Kent WA).

For the outstanding DMR-ES46V model the Panasonic corporate Service Center in Elgin Illinois offers the $130 flat-rate repair that will return your DMR-ES46V to new functional conditon:

http://www.avsforum.com/avs-vb/showthread.php?t=1056657

It's best to directly contact Panasonic's Elgin Illinois Service Center. That contact information is found in the first post in the linked thread.

If you call Panasonic Customer Service they may attempt to arrange (for $150 or so) an exchange through their McAllen Texas facility for an EZ series combo recorder such as a DMR-EZ37, DMR-EZ47, DMR-EZ475, DMR-EZ48V or DMR-EZ485 model. Those models are functionally inferior to your DMR-ES46V. Avoid those models!

FYI, I had a ez-17 machine that had the no read failure which I assumed was caused by a bad laser. It said no read with or without a disc in it. I looked on line for a replacement vxy1961 drive but did not find any. I did however find a refirbished vxy2010. So I decided to chance it. reading the posts on drive compatibility I assumed that the 2010 would not just bolt in and work, but after examinng the ribon cables and the mechanical parts between the two drives it looked like I could swap out the circuit boards between the vxy 1961 and the vxy 2010. I did and a few minutes later the machine was up and running normally again. It reads writes and finalizes ok. So the newer drive apparently uses a compatible laser. I wanted to fix the ez-17 because I really like the 2xlp picture which they seem to have dropped on the 2008 series models.

Wilmorr,

Your successful swap of a good 2008/2009 VXY2010 DVD Drive fitted with the on-board controller PCB from your 2007 DVD Drive VXY1961 confirms that these model DVD Drives will interchange as long as the on-board controller PCB is also swapped between those different model-year DVD Drives.

I've revised this thread's first post to include this news for those with Panasonic EZ series recorders.

Those swapping DVD Drive controller boards should notice that the connector for the laser assembly ribbon cable has a flip-up locking/unlocking mechanism as seen in the first two photos. Also notice the ribbon cable grip-tab orientations as seen in the fifth photo. The three upper ribbon cables have their colored grip-tabs facing outward while the lower copper colored ribbon cable grip-tab faces inward. (The ribbon cable functions are, from top to bottom, 1-disc tray and slide-cam motor—narrow green grip-tab, 2-spindle motor—blue grip-tab, 3-laser assembly data cable—wide green grip-tab, 4-laser assembly transport motor--copper colored cable with inward facing dark brown grip-tab, 5-the ribbon cable seen at the lower left of the on-board PCB is the data cable connected to the Digital PCB.)

In recent weeks one of my DMR-EZ17 models has been having more frequent scheduled recording lock-ups when transitioning from PAUSE to RECORD. I've been considering swapping that 2007 VXY1961 DVD Drive on-board controller board with one from another DMR-EZ17 DVD Drive that has a failed laser assembly. At this point I'm unsure if this scheduled recording lock-up originates with the DVD Drive on-board controller PCB or with the separate Digital PCB.

I have a 2008 DMR-EZ28 that has the VXY2010 DVD Drive. Should it have a laser assembly failure it's good to know that VXY1961 and VXY2010 DVD Drives interchange as long as the original on-board controller PCBs are swapped between these DVD Drives. (I have four DMR-EZ17 models, one set aside as a standby recorder, one in daily use but with increasing scheduled recording lock-ups and two with failed laser assemblies.)

With regard to failed laser assemblies, Mickinct has experience replacing laser assemblies for a wide range of Panasonic models. He has mentioned that a single laser assembly model may be used in several model year DVD Drives.

For those considering the purchase of a replacement laser assembly one may find the model number on the underside of the laser assembly itself. Examples from 2006 and 2007 model year Panasonic DVD Drives are seen in the third and fourth photos.

EBay seller Gazglasgow lists several popular Panasonic OEM laser assembly models but that seller doesn't provide a complete list of Panasonic recorder models that use those model laser assemblies.

Gazglasgow's eBay laser assembly listings provide some basic instructions for the replacement procedure. Other AVS Forum posts address DVD Drive tear-down and reassembly procedures.

The above boldfaced clarification of DVD Drive VXY1945 utilization has been made to the first post in this thread.

Why do the 2006 HDD/DVD models use a different DVD Drive than the "standard" models? The "standard" models record to DVD in "real time" (1x) whereas the HDD/DVD models offer the "high-speed dubbing" feature that may require a DVD Drive optimized for high-speed dubbing in addition to "real time" recording. Perhaps therein lies one difference between DVD Drive models in 2006 model year Panasonic recorders.

Good advice indeed, but note all my failures with the EZ-17s were on machines that I basically never played on. I would only use them to record to -RW discs, finalize them and then play on my DVD player. Reformat the discs and repeat again. I had much better luck with the EZ-28 but not quite up to the standards of the ES series.

Photo three shows a ribbon cable with a damaged contact strip. Sometimes it's necessary to trim back the damaged area as shown in photo four.

I don't play DVDs on DVD recorders. After reading the material related to laser hour utilization in Wajo's sticky thread I'm even more convinced that DVD recorder laser assembly longevity is vastly improved by using a DVD recorder only as a DVD recorder.

Avoid using a DVD recorder as a DVD player.

Yesterday one of my "daily use" DMR-EZ17 models suffered a DVD Drive laser assembly failure at around 1,523 recording hours. The DVD Drive had recorded satisfactorily earlier in the day but later returned a "no read" message and made the "clunking" "chugging" and "errrp" noises when attempting to read a disc, a common indication of a dirty lens or a failed laser assembly. That DVD Drive had its most recent lens and hub/spindle cleaning on 8/13/2009 so it was determined that a dirty lens was not the cause for the DVD Drive failure.

A "standby" EZ17 was temporarily swapped into its place, setup and configured. The disc in current use was also swapped into the "standby" EZ17, recordings were scheduled and completed and the disc was finalized. (This "standby" EZ17 has a problematic tuner but this was no impediment to its use with a composite input connection from a Comcast STB.)

This morning the "standby" EZ17 was removed from service and its good DVD Drive had a lens and hub/spindle cleaning. The "standby" EZ17 had its most recent DVD Drive lens and hub/spindle cleaning on 10/19/2008. Then that good DVD Drive was swapped into the "daily use" EZ17 that had experienced yesterday's drive failure. The "daily use" EZ17 was then returned to service and recordings have been scheduled. The swapped-in DVD Drive is attributed with 239 recording hours.

The former "standby" EZ17 is now a "parts machine."

I'm amazed at how many hours you're able to get on any of your EZ-17's. When I had that particular model I could rarely make it past the 30 day mark, and usually in less than 2 weeks I got the dreaded self check error and I could not get my disc out no matter what I tried(not to mention the tons of lost/missing events due to the timer bug).
In hindsight possibly if I had manually ejected the disc the machine may have recovered, as it was since my problems were almost always within the 30 day return/exchange policy(of the store I bought them from) I just opted for a new(similarly buggy) machine.
Did I ever say how much I detested the EZ-17/27 machines

Today I swapped DVD Drives between a DMR-ES15 (that had a good DVD Drive originally installed in my other DMR-ES35V "parts machine") and DMR-ES35V "6490."

The DVD Drive swap was successful! DMR-ES35V "6490," purchased in 2007 for $15.29, including shipping, as a non-functional "as-is" parts machine, was returned to normal functionality today. DMR-ES35V "6490" is now set up cable ready, also with a Zenith DTT901 connected to IN 1 to provide local ATSC (digital) broadcast channels. A successful test recording was made and recordings have been entered into the schedule menu.

While the original DMR-ES35V "6490" DVD Drive may be problematic, I have not yet checked out its operation in the DMR-ES15 where it now resides.

Photos taken during the DVD Drive swap are attached to this and the next post:

This is an update. DMR-ES35V "6490" has been recording 3.5 hours each weekday since the DVD Drive swap. Functionality is normal.

The DMR-ES15 that got the problematic DVD Drive from "6490" has been checked out for DVD Drive operation. As before, this DVD Drive plays discs but will not record. This DMR-ES15 has been set aside as a "parts machine."

I should mention that it is not necessary to remove the Panasonic front panel of 2006 and newer models when swapping DVD Drives.

It may be necessary to remove the Panasonic front panel of 2005 and older models when swapping DVD Drives.

If the front panel has been removed from a combo recorder take care to hold the VHS door open when refitting the front panel back to the case. This should correctly align the VHS door lifting mechanism.

^^Thanks. For clarification, let me say that, looking at the board, I assumed the ribbon cables were like the cables that are like a pc dvd drive, the flat cable with the connector that you plug or unplug. But as I discovered, the ribbon is just that, a ribbon, the flat plastic 'head' is attached to the board itself and not the end of the ribbon. That's what had me scratching my head. I honestly thought I'd torn the thing when it the copper ribbon came sliding out (I wasn't pulling on it). Note to any others who may wish to swap drives-it;s best not to unscrew the board from the drive, leave it screwed to the drive and remove the ribbons first. It was harder for me-a first timer at least, to figure out when I unscrewed the board first, expecting to disconnect the cables with ease afterward.

And the final results. Installed the VXY1961, screwed everything back into place and plogged in...the ez48 works again. Thus far, I played a RAM disc, and it's recording right now, tested chase play, commercial skip while chase play, stop playback while recording, and everything's working..,

Many thanks to Digado, Wilmorr and all other contributors to this servicing thread. Great advice and direction found here on the mighty AVS Forum.

I've just come across these 2008 and 2009 photos. The first photo shows closer detail of DVD Drive ribbon cables/connections in my DMR-EZ28. Notice that the copper colored ribbon cable has a different grip-tab orientation than the other ribbon cables and that the widest ribbon cable with the green grip-tab has the locking/unlocking type connection while the other ribbon cable connections are of the the direct insert type. The second photo shows DigaDo grasping the ribbon cable and grip-tab in order to disconnect the ribbon cable from its connection on the Digital PCB in a DMR-EZ17.
