Note: If you do this, the laser trimpot on the board MUST be adjusted. As this assembly is designed for the PSOne, it must be gapped to fit these units with spacers. If you have a issue with this laser beyond the ability to adjust it, the KSM-440BAM laser may work, depending on which system you own. Playstation, Evolution, Wikipedia, Wiki, PSone, PSX, Sony, Computer, control pad, Dual Analog, DualShock, Nintendo, Super Famicom, Memory Card, Developers kit, Swap.These use a magnesium optical block, and do not wear down like the plastic block. This guide is intended to be used on the KSM-440ADM laser, or newer.You must replace the laser unit on these - no way around it. These fail due to a plastic optical block known for physically degrading.

Is it properly a BA6397FP problem What PS1 model should i go after and leave out the SCPH-1001 SCPH-5501.

THIS WILL NOT RECOVER KSM-440AAM and ACM laser assemblies. Should i get an SCPH-5501 since it has the same CXA1645 encoder and fixes a laser issue and automatic BIAS and GAIN and put the AEM laser in for 550I am done with the SCPH-1001 so i destroyed 3 of them.

This is often a temporary or partial fix! While you may permanently repair the system, it is very unlikely to hold up over the long term.

SCPH-5500 NTSC-J SCPH-5501 NTSC-U/C SCPH-5502 PAL So if you have NTSC-U/C game then you need 5501, etc. The laser needs to be replaced and cannot be reliability re-adjusted. PCSXReARMed is using three different bioses for three game regions. In the case of the system used for the guide, it was only recovered to 50-60% read after adjustment. On many of these older Playstations, this is a known failure point. 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 replace the failed laser unit.
