DVD

try blowing it out with a can of compressed air even with the door closed and not being used that much the laser will still get dust on it and not read like it should and cause the dvd to freeze up, you might have to take the top cover off to get at the laser which is a round small red thing smaller than a dime .spray all around the track real good

Make sure that theres no smudges on the disc ie, fingerprints or scratches. If all the disc are fine then the slider or tracking motor and or cuirutry is at fault

Pull the cord to shut off the unit then plug it back in again.

Hold the power button in for about 10 seconds.

If your burn your own DVDs, make sure you do this in the "most compatible" format. Some applications won't burn DVDs according to the standards. It could also be a misaligned laser or scratched lens.

I need a phone number for Lasonic. I need a part. HELP!!!

How do I tell if the tracking motor, slider or cuirutry is at fault?
