My PS2 (MODEL 50001/N) took a fall from a good enough height by an over-enthusiastic gamer, and now I get the dreaded DRE and can't load any games. I tried to use some of the techniques I read about on other sites that reccomended adjusting the little white dial behind the laser, but my model has two adjustment knobs for the laser. made adjustments still doesn't work. short of sending it back to Sony, (it's past the warranty time, of course)what else can I do? Help!
