Blinking red light then shuts off
When turned on, power button is green then goes to red blinking 25 times while fan sounds like it's at max rpm and it begins loading xbox logo on screen but then screen goes blank before system shuts off again. Cleaned fan and heatsink and replaced thermal compound but problem persists.
Any ideas? I suspect a possible GPU solder issue but haven't seen that problem behave this way before.
Is this a good question?
