TV/VCR/Stereo Troubleshooting/DVD player will not work


I have a JVC DR-MV79B DVD/VCR Player/Recorder. The problem is when I load a blank DVD disc or a pre-recorded disc, the unit says "READ" on the machine but then it will open the tray door and says on the TV "Unknown Disc, Please Check Disc Again".  Any idea what the problem could be?

It could be a technical problem requiring a repair or adjustment - which would require taking it in to a JVC authorized service center.

Or, it could be a compatibility issue. The specifications on this model say it will support +/- recordable and re-write formats.  Check the format of the discs that it does not take.  That may be the problem.

Also, this model is getting old and the laser diode which reads the disc content may be getting weak.  If it reads CD music discs just fine but not dvd play or recordables then it is often the laser getting weak.  Why? Because the dvd disc read and write takes quite a bit more energy output from the laser to operate in the dvd mode.  

Hope this helps you find a solution.
