I picked up a dead jaguar that looks like it was the victim of the wrong power supply. I changed reg 1, a bad cap, and the chip next to the cap. I did manage to get the power light back on but there is no video or audio from the AV jacks. The RF out shows a black screen when connected. I was thinking of buying a replacement motherboard unless someone has an idea of what isnt working. I would like to get this board fixed.
