Introduction
There are many FAQs reg a r d ing the adjustment of PS2 Laserunits (LU), as Sony seems to adjust ´em
too careful, so the LU has a greater life expectance, but the PS has difficulties r eading some DVDs or
gamediscs (backups ?).
Most of the answers give advice to screw a little bit on the laserpots, but that´s a real ner v e w r ecking
way of getting your PS to work.
This reworked and rewritten tut orial gives explanation to properly adjus tin g the LU.
There also seems to be a problem with some batches of PS2 - the LU dies and the PS2 can´t read DVDs
and/or CDs anymore. Fortunately th ere ar e some vendors selling r efurbished or new laserunits - the
problem is that in most cases you have to replace the unit yourself. The explanations and aproaches
given in this tutorial are meant as a help performing t his task.

a) SCPH 10000
1.
Remove the bottom and to p cover by removing the screws under the small pla st ic/rubbe r pads.
2.
Remove the metal r f i-sh ieldin g at the bottom ( pcb ) side.
3.
Unplug the flat wire band from t he drive connector by lift ing off the clamping bridge (carefully!!!)

5.
Turn t he machine back to the bottom side and plug the wire band back to the connector .
6.
Place the drive that you can access the drawer, without bending the flat wire band (I put it on the
pcb, isolated with a sheet of paper and „up-side-down“ to get access to the adjustable resistors) .
