I've had my Sony 530D DVD player for about 2.5 years now, and the only problem I've had until now is the lip-sync problem (which I had fixed by Sony). Today I watched "UHF" and the video froze for few seconds during the opening credits. Then about halfway through the film, it froze again. When I pressed Stop, it displayed "C 13:00" on the screen. Now it won't play any DVDs or CDs -- it just displays "NO DISC". Has anyone run into this problem before? I don't know for sure if the "UHF" disc is to blame, or if my DVD player just suddenly decided to stop working. I tried performing the Drive Auto Adjustment in the service menu, and it gave me an Error during the "Sled On" step. Any help or suggestions would be appreciated.
