I've a UJ-811B dvd player, it plays dvd's, but it doesn't read or write any data. I'd believe that the lense it's dirty, but it plays
movies. What steps should I take.
Dismantle it, re-align the laser (look at some PS2 forums for that, google search 'fix a ps2'). This is usually trial and error! I'm trying to fix mine!
