Playstation 2 Laser Calibration using Oscilloscope If your Playstation 2 has trouble reading certain discs it is probably due for a thorough cleaning and maybe laser calibration. Use a miniature vacum cleaner, canned compressed air and cleaning buds with isopropanol alcohol (IPA) to clean out all dust and dirt from the Playstation 2 including the laser.

I can not take the time to answer hundreds of personal emails with similar questions every day :-) Caution! If you have any warranty left, always claim a warranty repair instead of doing any work yourself. If you open your PS2 you will break the warranty seal and the warranty will be VOID! The laser is VERY sensitive to electrostatic discharge (ESD). Always work in an ESD-protected area when you service the Playstation 2. WARNING! When you perform laser calibration on Playstation 2, you will connect live 110V or 220V power with your console opened. This mean LETHAL danger.

But the reason you use variable potentiometers is that every PS2 need individual adjustment, so you cant use one reference value. What you need is an oscilloscope and/or a laser power meter to measure what is going on when you turn the pots. It is always best to measure on a brand new well working PS2 to get some reference values to use when you are calibrating a bad laser. If you have a laser power meter you just have to put the photodetector above the laser lens and look at the readout. If you are using an oscilloscope you have to know where to find the RF/Eye Pattern measure points. Laserpotentiometers on the PS2 This is a picture from the underside of the PS2 Laser. The pots are marked on the picture. Turn clockwise to increase power and counterclockwise to decrease power. Dont turn those in the blind, or you might kill your laser using to much power or just be unable to get back to a working setting. Now, get
