I just put a matrix infinity into my JAP V4 PS2. First of all, i can't play the original jap game. if I try a backup one, it keep reading the disc and have no result. and I have removed two original wires, the SCEX and the RESET and tried to start the machine, the reset led first become red and then brighter and brighter and then disappeared. burnt! and I can do nothing.... would somebody tell me what to do beside buying a new one?
