Late 2009 iMac video card fixed but won't boot after reassembly
I just replaced my iMac’s video card with a used card which allegedly is working (100% rated seller) but the machine will not boot after reassembling. Power seems to be on, fans kick on, but no boot, no chime, no display. We blew out the dust with an air compressor (set not too strong). We’ve double checked the various connection cables etc. Wondering what we may have done wrong or missed. We’ve redone our video cards before and not had this issue. One comment we saw mentioned removing and reinserting the battery on the logic board to reset. Sounds like a hassle, so would rather not have to pull it all apart if someone has another suggestion. Any help would be immensely appreciated!
Esta é uma boa pergunta?

What does the onboard diagnostic LED’s telling you?

I have no idea. They do not seem to be lighting up. I should add that we ordered a video card that is slightly different from the original (a year or two later model, 5750), which we read would work. We are currently cooking our old one to see what happens when we try it with that. We thought we'd just replace it but maybe this will be helpful in deducing something.
