i installed my Duo2 chip, and everything looked good connection wise. now when i turn on the ps2 and put in a gmae, i hear the disc being read and everything, but there is no audio or video output to the tv. the fan doesnt seem to come on either...im just worried that ive completely messed up my ps2. like i said though, everything was done as the instructions said, and all the connections looked good. am i screwed?
