The lasers in these are pure garbage. The early units use plastic gears, so you need to check if the parts are plastic or cast metal. If they’re not metal, you NEED to change the laser unit and there’s no way out. The plastic ones usually fail exactly as you’re seeing it, so don't keep your hopes up too much.

It is possible to fix it by adjusting the trimpot on the board, but you need an oscilloscope to adjust it right - not many people can do this.

The second option is to trimpot the motor to slow things down enough to get it to work with the unadjusted laser, but if you ever trimpot the laser you will need to fix the laser adjustment - mark the factory ohm adjustment on the laser so restoration to factory is easy. However, you will need to adjust both if you ever trimpot the board and do a full repair later on. Before mine was too far gone to adjust, I did [guide|47857|cover the procedure]. It will never be perfect, but it’s better then nothing. Don’t worry about MINOR FMV issues; it’s normal on many of the internal supply PSX systems. I had to completely rework the text since it was 4 years between this answer and the guide, so hopefully my bases are covered.
