It's not worth fixing. Usually it's the laser diode that is shot. To fix it you need to replace the laser diode/pickup assembly and then use an oscilloscope to adjust the power level and focusing setup. If you don't do the power level adjustment, you risk burning out the new LD in the pickup. Takes a shop about an hour to an hour and a half to do, on top of parts cost. Not worth it when replacements are available at such a low price. Usually when the laser goes bad the player will try to focus on the disc to get a readable signal and you'll hear a 'boing boing' sound as it moves the lense around(sometimes you'll actually hear the lense hitting the disc).
