I have a Tascam DV-RA1000HD that I haven’t used in a very long time. Recently I tried to use it and it does not operate. I got the following results: After turning on the power switch the display shows “Initializing DVD Drive…”, then displays “Please Wait”. The display stays this way without changing. The ODD light is on. If I press the HDD button the display shows “FAT could not be mounted. So cannot change to HDD mode.” In addition, if I press the “Open/Close” button, the display shows “Close”. The DVD tray will not open on repeated pressing on the button. The “Close” message will not turn off. When I check the FirmWare version it says: Ver. 2.01 Build. 0049 Drive Ver. (blank) Also, I checked the battery, the screen displays what appears to be a battery with the inside image solid white. Since the date display was correct, I assume this means that the battery is still fully charged. The Owner’s Manual is not clear on showing what is displayed for a fully charged versus dead battery. So here are the questions I’m hoping someone can help with: Any idea what is wrong with the unit, basic things to check? Are the two issues related? Is there a service manual available? I searched online but did not find any documents. I have seen in a few old posts that owners have replaced the DVD drive as well as the HDD using non-Tascam factory parts. Does anyone have the specifics of the make and model of the drives used and the procedure involved? Again, my search efforts found nothing. Of course sending the unit to TEAC/Tascam for servicing is possible as a quick phone call revealed that factory parts are still available (but this option may be cost prohibitive). Thanks.
