Adjusting the laser voltages involves taking the bottom off of your PS2. So let's get started.
This procedure is for version 1-3 – Please see next section for version 4 and higher.
A. Flip your PS2 over so that the bottom is facing up.
B. Remove all the screw covers. (
There should be 6
screw covers, 4 made of rubber (outer edges) and 2 made of
plastic (in the middle), that need to be removed. Indicated
in photo by the white lines. You can use a knife or small
jewelers flat blade screwdriver for this. There should be 2-4
more screw covers on the outer side of the base,
underneath the controller ports. Indicated in photo by red
lines. The older model PS2's have 4 screw covers, while
the newer ones have only 2. Remove them all, and you
should now have a total of 8-10 screws unveiled.
Set the screw covers aside.
