3)Lift out the expansion bay housing. It is attached to the circuit board by a short ribbon cable. Under this are the laser control screws.
4)The laser control screws are on a small amber circuit board slightly recessed in the plastic case. You will be adjusting one or both of the two small silver screws with a black screw in between them.
With the front of the PS2 facing you, the silver screw on the LEFT controls the voltage for the CD reading. The silver screw on the RIGHT controls the voltage for the DVD reading. I suggest putting a small dot, with a permanent pen, in the 12 o'clock position of each screw to help with the adjusting process...
5)Stand the PS2 on its side (vertically, memory cards at bottom, power button at top) at a slight angle. You will not be able to stand it at this angle unless it is done on carpet floor.
Having a friend hold it in position might be better.
Make sure that the expansion bay housing does not come in contact with the circuit board, as you will be turning it on, and you don’t want the metal housing to short out the board. Let it hang down, away from the board.
