I have a DMR-EH50, which has operated basically unsatisfactorily ever since everything went to 16x media. Recently, it had gotten where most anytime I went to eject a disc, particularly after recording to it, I would have to go through approximately 10 minutes of "Self Check", "Please Wait", "Error has occured, please press ENTER", "Please check the disc", "Please change the disc", etc. Usually at least four of those five messages each time.
By the way, I did install a firmware update several months ago. I had tried burning the update from Panasonic's website to CD in every possible format with no success, and when I e-mailed Panasonic about it, their only response was to mail me a CD of the upgrade, which installed successfully, but made little to no difference in the operation of the unit.
Having become fed up with the unit's recent performance, I decided to open it up to look into the possibility of switching out the DVD drive, as I've previously done on a LiteOn recorder with excellent results. Well, as I discovered, and some of you are probably aware, the drive on the EH50 doesn't exactly match a generic DVD burner, and this was likely not a feasible plan. Nonetheless, as long as I had the thing apart, I went ahead to see what would happen if I took the data cable that was attached to the built-in drive and instead attached it to the port that it would fit into on a standard DVD burner. I believe this would be either the mono or digital audio output on the drive, while powering this external drive with a normal computer power supply. Yeah, it was a dumb thing to do, but I was guessing it probably wouldn't do any harm, which was probably a wrong assumption on my part.
Anyway, all it would do if I tried to start up the EH50 on this configuration was a never ending "Please Wait". If I'm recalling correctly, it would give that message with the external drive connected to the data cable, whether the drive had power or not. The EH50 would do nothing at all if I plugged in the unit without having anything whatsoever attached to drive data cable.
So, having no success therein, I put everything back together the normal way, hoping to at least return to the unit's normal substandard operation. It was somewhat difficult getting the drive's power ribbon-cable reconnected, but I believe I have properly done so, along with the data cable. I also performed continuity tests on the ribbon cable, and while it would be difficult to ensure continuity on every single connection, I know that some are working and have no specific evidence that any have been broken.
However, now, no matter what I try, when the unit is plugged in, all it will do is endlessly display the "Please Wait" message on the front panel, and does not respond to anything. Is it likely that I have damaged or burned out some component? Does it sound like I just have something connected improperly?
Any advice that anyone can offer would be greatly appreciated, as there are no shortage of items on the HDD that I would be interested in retrieving. I'll consider taking it to a service center, but I would rather make the repairs myself, if possible.
Aside from the data on the HDD, it would be nice to have the unit working again, but that's not something I'd put much money into in itself, as I'd rather buy a unit that will transfer digitally from DVD to HDD. Speaking of which, I see on page 43 of the manual that the EH50 supposedly will high speed dub to HDD from DVD-RW recorded in DVD-VR mode, which is not the mode that the EH50 records in. I have tried this with discs from another recorder made in that format, but to no avail. Has anyone ever had success in this?
Thanks in advance for any help!
