Have you had problems with your PS2 giving you crap about not being able to read blue disc? well try this!Before I tell you make sure the system is off. first: take all the tabs out from under the system ( find a way to remember which spot each one goes in) second: unscrew the screws from under the tabs ( remember which one goes where) third: take the top off of the PS2 so you see inside DO NOT RIP SILVER RIBBON CONNECTING THE COVER TO THE SYSTEM!! Turn the system on and hit the eject button and then turn it off with the disc holder out. fourth: there should be a kind rectangle shape box on your right-hand side, unscrew the very small screws. fifth: pull the top of that off. sixth you should see a white knob type thing , turn clockwise and you will see the laser raise. seventh: raise it about half way. eight: get some purtrolleum jelly and with a little bit rub it on the rods that the laser is connected to. ninth: put the top back on and screw the screws. tenth: turn on the system and make the disc holder go in. eleventh: put the playstation top back on and screw it together. twelve: get a blue disc and put four pieces of tape around the center of the disc on the side with the pic( tape sizes are about an inch) thirteenth: breath warm air on the back of disc and on the sides of it, then wipe it on your shirt or clothe. fourteenth: open tray and as the system is starting hit the blue button for tray, and when disc goes inside go to browse. and the disc should show up. this works for my disc.
