LogicBoard 3 led on but no video no sound
I have Replaced the logic board because it was damaged. It only showed 1 of the 4 LEDs. Now with the new board I only get 3 of the 4 lights and it doesn't give me video and no startup sound either. Try everything, disconnect disk, other rams, etc. I can't find the problem any ideas? THANK YOU
Is this a good question?
