I have a Sony DVP-NS315 DVD Player that was playing just fine until a few days ago when it started giving me an error message saying it "Cannot play this disc." I've tried multiple commerical DVDs, and I get the same message every time. There was a post about a similar issue with a Sony player in this forum, and the advice was to clean the laser lens, so I opened up my player and cleaned the lens. I tried a disc after that, and it would not spin at all in the player. I tried another one, and it did the same thing. When I went back to the original disc, though, it suddenly started spinning and playing. I then ejected that disc and tried it once more, and it didn't work. Since then, the player has played a disc one other random time, but I can discern no pattern or reason that it would work one time and not another.
Before the player gives the error message, the disc will not spin at all, and I can hear the laser moving around (like an etching sound). When it does play a disc, though, the player spins the disc immediately upon insertion. I've read that some people have got this error message from Sony players and had to replace their players, but because mine works every so often, I wonder if it's salvageable. Could there be some problem with the spinning mechanism that would cause it to work only sporadically?
Also, I'm not sure because I was asleep at the time, but there's a chance that the error message could have appeared after a brief power outage at my house. (I had to reset the clock on my microwave when I woke up, and my computer had mysteriously restarted.) Could a power outage have affected the DVD player if it was on and had a DVD inside?
Thanks for your help!
