Introduction
Is your PlayStation SCPH-550x having trouble reading games? This guide will show you how to extend the life of the existing laser you already have so you can either get another system, or fix the issue with a new laser. Laser assembly failure is a known issue in some of these older PlayStations. [ … ] In the case of the system used for the guide, it was only recovered to 50-60% read after adjustment. This one needs a new laser. [ … ] '''++Guide notes++ ''' [ … ] * '''This is a temporary fix! While you may permanently repair the system, this is very unlikely to be anything more then a short term fix.''' * '''''THIS WILL NOT RECOVER KSM-440AAM and ACM laser assemblies. These fail due to a plastic optical block wearing out. You must replace the laser.''''' * '''This guide is intended to be used on the KSM-440ADM laser'''. These use a magnesium optical block, so they do not wear down like the plastic one. * If you have a issue with this laser beyond the ability to adjust it, the KSM-440BAM laser may work, depending on what model system you have. This is a PSOne laser assembly, sp spacersassembly. Spacers are required during the retrofit installation. '''Note: If you do this, you will need to adjust the laser trimpot on the board!''' '''Note on adjustment specifics: I cannot provide an adjustment reference. Every system is going to be unique, while others will have to be deemed beyond repair. The system I used only recovered with a 50-60% read rate.'''
