Cleaning & Adjusting the PS2 Laser:

From yallcenter.com Before attempting the risky procedure of adjusting the power to the laser via the pots, first try to clean the laser lens, as this is known to build up a thin layer of film which can reduce the laser's ability to read data from CD's and DVD's. Using the disassembly instructions that can be found on this and other sites - remove the 8 or 10 screws from the base of the PS2 (found under the plastic and rubber tabs). Turn the station over and carefully remove the plastic top - making sure not to damage the reset cable that is on the same edge of the case as the Reset and Eject buttons.

You will then see the following plastic drive exposed. Remove the indicated screws and lift the drive cover off.

Gently wipe the Lens with either a Sunglass cleaning cloth or a cotton bud with non-corrosive cleaning fluid such as pure alcohol.

Whilst in this area, ensure that any other visible dust and hair is also removed, greasing the sled may also be performed whilst

the laser case is open.

Adjusting Lens angle (Part 1) - On V1-V4 playstation laser assemblies there is a visible white cog (pictured below) that enables you to adjust the angle or height of the sled as the lens moves to the outer edge of the disk. This adjustment is also known as the Radial Skew. As the laser gets old or worn - it may help to adjust this to bring the lens closer to the disk. V5 to V10 lasers also have the cogs, but they are not as obvious.

To perform this adjustment:
1)    Eject the tray so that it is out of the way.
2)    Mark the original position of the cog with a black marker pen.
3)    To raise the sled adjust anti-clockwise
4)    Only adjust one or two clicks at a time
5)    After each adjustment test with both CD and DVD media.
6)    Repeat until desired improvement occurs.
7)    If no improvement - set back to original position.

Adjusting Lens angle (Part 2) - Known as Azimuth or Tangential Skew adjusting. This will adjust the angle the lens sits at on the sled. This should only need adjusting when replacing lens units - even then, the factory set angle should be fine!
