What you will need:
PhilipsScrewdriver(Normal)
PhilipsScrewdriver(Eyeglass)
Cotton balls or swabs
Rubbing alcohol
Felt tip permanent marker

First look on back of PS2. Now all the way to the right there is a Warranty sticker. Either peel it of or cut it in half. Now turn it up side down and pull out all the screw caps and remove screws. Flip it back over and lift from back and pull towards you. Be carefull cause the ribbon cable is attached to the cover. Take the cover lay it so the side with the PS2 logo is laying on ground to the right of PS2. Take the eyeglass screwdriver and remove all the screws on the top of the laser lens cover. (It is the big black square that says laser warning on a yellow sticker for the slow ones.) Now dip the cotton balls/swabs in rubing alcohol. Rub the laser lens in a circular movement for 30 second. Rub dry with dry swab and repeat in other direction. Now put a disk on and place the cover over it and test it to see if it now works. If it does reasemmble your PS2 If not then take the cover back off and the cd out. Look behind the Lens and tehre should be a little white gear. To left side of the gear there is a metal notch. Take the marker and mark wich notch it is on. Rotate it 2 or 3 ways to the left. Test it. If nothing try 2 or 3 right. Keep playing untill you have got it working and then Reasemble your PS2. Now it should work yay.

I will add pictures and stuff when I find my camera.

I ripped apart a PS2 in order to get the BIOS from it. Trying to make a working emulator for PC lovers everywhere!

Selling working PS2 BIOS! Only $150.00 =^_^= (j/k, folks, but I DO have a working PS2 BIOS)

the thing is now that we dont need to repair a ps2
we can all buy one now quite cheapley...especcially now the PS3 has come out
p.s Dont get a PS3...............360 ALL THE WAY

actully i take that back the newer systems are bad on graphics: my friends had a ps3 and Xbox360 . the ps3 has glithes in it so they now rated the ps2 with better graphics. one of the GAMES for the ps3 had a problem called ground zero where you jumped into that hole and you would never get out even when you restarted the game you still couldnt get out. the Xbox 360 has bad graphics because its graphics processor is made by ATI which is also in the nintendo gamecube which has the worst graphics ever! now the original Xbox graphics processor was made my nvidia which is in the new computers today. now nvidia is the best graphics for computers and game consoles.
