Check <a href="http://www.eurasia.nu/wiki/index.php?pagename=Ps2LaserAdjustmentAndReplacementGuide">here</a> for a guide to realigning your laser if you're game. Once again I can't stress enough how important it is to be careful when doing this. NEVER touch the laser lens or try to force anything, only twist the one cog required to change the alignment and only twist one or two clicks at a time, and test the disc read in between adjustments. Also, I highly recommend marking the cog so that if nothing else you can return it to the original position.
