A little off topic here but I need help and know that someone here can help and knows how to do this, I don\'t want any companies replying about this laser kit fix or this kit, I mean I can buy another PSX for the price of some of these things, and I already have a PS2 anyway to play my old games on, I just want to see if I can get this old PSX running. The laser slides look OK not really any wear and the laser will move up and down when the door switch is activated. The CD won\'t turn now though, my question is which of the three potentiometers do what and what does the vlotage settings need to be and where exactly do I check that voltage? Thanks if anyone can help.
