My Red God of War PS3 Super Slim will no longer turn on. I recently moved and finally pulled it out of the box. It turned on briefly and then immediately shut off. I troubleshot the system and determined the power supply was dead. I ordered a new power supply, installed it, and the console turned on briefly and shut off again. I took the entire thing apart and put it back together again thinking maybe there was a short somewhere. It still will not turn on and no lights come on on the front. Is the motherboard dead?
