Have a v9 here that will not spin discs at all, the laser is new from a different system (KHS400c). I had to replace the LA chip in the system, so i did with one from worldmodchips, and now eject light is lit, system ejects properly, and the laser turns on (emits red light). However the spindle that the disc sits on will not spin at all, it doesn;t move actually. What could be the problem? Cleaned the motherboard, and checked fuses, all good. Thanks!!!
