Got what I thought is a classic 2011 15inch GPU issue.
Machine looks clean turns on and chimes but just shows a white screen
Removed board, disabled GPU by removing R8911 fitted Tiresias, pop board back in to test before adding brightness control wires and it turns on chimes back light comes on but all I get is a black screen, tried logic board in known good working second machine same result.
Is this a common issue, a dead Tiresias or maybe not a GPU fault in the first place?
