Laser Voltage Adjustment For Version 4 On Up - Sony Playstation 2 Repair Manual

LASER VOLTAGE ADJUSTMENT FOR VERSION 4 ON UP

I stated earlier that the version 1-3 adjustment procedure was just on the edge of what I think the average do-it-
yourselfer could do, and this procedure for version 4 and higher is even a little more difficult than the last. I
have included it though to make the book more complete. Proceed at your own risk.
You will need silicon grease while doing this procedure. Radio Shack-# . Best to get it before you start

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.
C. Use your knife to cut the warranty tape that is covering
the seam between the back and the top cover. (By the

knife so that it will not be holding you back when you go to
remove the top later.
Using the normal sized Phillips head screwdriver, Make sure all of the screws are removed, and put them

aside.
NOTE: Some of the screws are longer than others. It is VERY IMPORTANT that you remember where the
longer screws go. You may want to mark the holes with a piece of tape or some other way so that you will know
which holes the long screws go into. If you do not remember where the long screws go, you could put a hole
through a circuit board by trying to force the long screw in where it is not supposed to be.
