I have a Macintosh Performa 5260/CD that appears to be dead. When plugged in and turned on, it gives a faint clicking sound, no video, no chimes. On disassembly, I noticed like a fine soot. Pulling the power supply board, I found what appears to be a burned up resistor (“r814”?). However, since the old part is toast, I don’t know what to replace it with.
Can anyone point me at specs for this board? Or even a photo of a board? My understanding is that this all 52XX share the same form factor, so if I could get the specs for one of those boards it would probably work. 54XX might also be similar (however, they are PCI not Nubus, so who knows).
I’m not sure I want to just wing it on a power supply. I’m also not sure if this is the only issue with this machine, but it does appear to be at least the most obvious problem. If I can get this running for the price of a resistor, then it would be a sin for me not to at least give it a shot.
