JVC DR-MX1S stopped recognizing DVD's - How to repair?
I have this unit for about 6 years. Several weeks ago it stopped recognizing DVD's. It will still play audio CD's. I have seen other statements that separate LED's are used for CD and DVD. I went through the lens cleaning procedure given on this web site, and only see one lens, unless both LED's use the same lens. Didn't help.
I went to the JVC "store" online and found a 'DVD drive kit' for this unit for $150. I knew that the model drive I had was discontinued, but I ordered it anyway, hoping it wouldn't be too difficult to swap it out. My mistake. The kit consisted of a DVD drive, new mounting bracket, and numerous other capacitors, cables, etc. No info on how to install any of it. I contacted JVC parts department (customer service), and was told I needed the service manual. I found one online for this unit, but it does not include any upgrade/replacement info. If anyone has anything that might help me, I would sure appreciate it, or else I'll have to try to return the kit. I really would like to get this fixed without sending it in to JVC service. This unit has been very versatile and reliable up to now. I can't find anything else that can do all this can for a reasonable price. Thanks for any help I can get, Ron |
Hi Ron, welcome to the site. :)

Let me know how it turns out. I'm quite interested. :) |
Thanks for your reply. Here is what I found out.

I fear there is a firmware change needed to use a different drive, and if so, I am out of luck as I don't think I can make any changes to it. Again, thanks for the help, I still have a few days before I have to get an RMA to return the kit. Ron |
The drive will need to match. I don't believe the JVC DVD recorders used NEC drives. I could be wrong, however, as it's been years since I had to dismantle one down to the drive assembly. Have you tried to install the DVD drive from the repair kit? It sounds like you received all the right parts (drive) plus other stuff in a "kit" that wasn't really necessary, though it could come in useful for later maintenance.
"LOADING" is a generic error message. It likely did not understand the drive's firmware, as you've guessed. |
The drive in the kit is a bare-bones unit, no metal case, does not have the usual power connector or I/O bus connector. Instead there are what looks like micro-connectors of some kind. Must be what the cables included are for. I would probably be better off to just return the kit if I can instead of trying to install it and screw it up.The model number on the replacement drive is PMD-0123A-C.

Then there's a chance JVC sent the wrong kit. :(

Maybe, but I doubt it. You said "Several off-the-shelf consumer DVD burners are known to work in this DVD recorder".
You happen to know which ones? |
Not from memory, no. It's been posted on the forum, however, by various members of the site.
There's a stuck thread dealing with the JVC issues here: http://www.digitalfaq.com/forum/home...g-jvc-dvd.html Inside, you'll notice links to a number of threads on this site and another one. In there, I'm pretty sure some drive models have been discussed. There's also some links to a few other dead-traffic sites; you won't get any help there (nobody will ever reply), but you'll be able to read past posts. I don't remember the .com names of those sites off-hand, either. I'd be doing the same as I'm suggesting for you: look at past posts on this site, and see what you can learn from there. If and when you do find the models that are supported, definitely come back here and post them. It's folks like yourself that help build this site into an "FAQ" of information. As much as I'd like to take the credit, it's not just Site Staff that help build this place. Keep in touch, as I'd like to know how this works out. :) |
