I agree. If the iMac had been making occasional snapping or crackling noises, accompanied by screen flashes, then it most likely was the flyback transformer giving up the ghost in one last giant short-out. Of course, it also could be something on the logic board or daughtercard. I just brought back to life a trayloader that had two problems: a dead flyback transformer *and* a daughtercard that had shorted itself out due to corrosion of solder joints toward the outside of the card caused by sitting too long in unheated storage in a rainy climate. Who knows, one might have led to the other or vice versa. YMMV. Jim Scott -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
