dang, i haven't visited my thread for like 2 months! ha, ha. btw i'm glad that you guys made this thread interesting.
anyways, i had originally purchased a refurbished 400c on ebay for $30. the 400c laser replacement was intended for one of my v.9 console that had a dead laser. i had decided to apply the romeo mod but it went wrong . i managed to lift leg 17 from the LA chip but i broke it as i was trying to solder the cable that would run to a 5 volt solder pad.
so, i had just bought an scph-35001 (not sure if it's v.4 or 5) for $5 from some dude that found it in a closet when he moved into his apt. the power supply or fuse was faulty but i ended up swapping out that power supply from another junked ps2 that i had and it worked.
i went ahead and put the 400c on this console and it worked without calibrating it at all. the only issue that this laser has is that it fraeezes occasionally during dvd movie playback. plus, the grease had dried up on the laser's roller bars (used wd-40 to to make up for it) and the disc tray ejects slowly. have any tips on this fellas?
