Found a PMG4 MDD today for $10, and it came with an old Apple Studio Display, too! Unfortunately, it doesn't power on due to (as the guy that sold it to me said) a power surge from the lightning storm we had a few nights ago. Said that the power button light would come on for a second and then go out again. I immediately suspected a failed PSU, but I supposed not.
Supposing that the PSU was still intact, I went to google to see what people said about this. Some said that a dead PRAM battery could make the MDD refuse to boot, so I took the old one out to do a PRAM reset while I went out to buy a new one. When I got back, I replaced it and tried to power on and... nothing. Then I tried a PMU reset by pressing the reset button on the logic board. Still nothing. I tried taking out all the RAM and putting one stick in at a time to see if any of it was bad. Nothing. Finally, I looked to the red light that people talked about, as it apparently tells you if power is coming to the board at all. No light when pressing the power button
I can only now guess that either the logic board or the PSU (or, hell, maybe even both) were fried in the power surge the dude told me about. Hopefully I can find a replacement for cheap online or something. But before I do, any suggestions from you guys?
Oh, and the silver lining? I got a working studio display out of this
