Have a 60GB model that a YLOD'd a few months ago, finally got around to fixing it (used the instructables oven method. seems legit.) anyways, been playing it pretty solid today, until this last time I went to power it on. The green light comes on like normal, but the controller wont sync, no video, no audio, and from what I can tell the fan is barely going. Is this a dead system or is there a chance I can repair it again? I'd really like to keep this one, backwards compatible and cfw 3.55.
