| In this guide, we will be looking at adjusting the trimpot on the PS1 SCPH-5501, to '''extend the life''' of the laser. It is quite common for the laser to stop working on these, due to these having a laser assembly that is known to fail in many models. You can replace the laser or adjust it and not have to worry about replacing it until you need to or you replace the console. |
| '''This is not a proper fix! This is to rescue a unit you had fail you already own or got and realized it was sold because of this. Treat it accordingly.''' |
| This will only work on KSM-440ADM laser assemblies, and newer. It will not fix the KSM-440AAM and ACM lasers. These fail because of the plastic wearing unevenly. You can '''potentially''' fit the KSM-440BAM(PSOne White) laser in the models that use this, and even the ones that don't support it officially from what I am reading. A lot of these do require modification, though. All of the models this mod works on natively need a modification done, where additional plastic is added to lift the laser. |
| Is your PlayStation SCPH-550x having trouble reading games? This guide will show you how to extend the life of the existing laser in the system before you replace it, or get a better system. The reason for this guide is because the laser is a known issue on these systems. |
| ''' ++Some notes for this guide++ ''' |
| * '''This fix is temporary, at best. It may fix the system for good or it may only fix the system in the short term. There is no way to know how long the repair will last.''' |
| * This does not work on the KSM-440AAM and ACM laser assemblies. These lasers fail because the optical block is made of plastic and wears out from use over time. These can only be fixed with a new laser. |
| * This guide only works on the KSM-440ADM lasers. These can be fixed because they use magnesium optical blocks instead of plastic. |
| * If you have a issue with this laser beyond adjustment, you can install the KSM-440BAM laser from the PSOne White system. You will need to adjust the laser and calibrate the board, but this laser will work. However, you have to space the laser because it's too small to fit in the SCPH-550x laser natively. |
