hello,
i have a 2915 with gpu problem. i replacede the gpu, now the picture is ok
and ASD is passing all.
if i start from my ssd in sierra and i start the benchmark software Heaven to test the gpu. i can see it switsching and it is loading and just in the moment it should start the screen goes black.
i replaced already the 3. GPU but nothing is changed.
I measure the PPVCORE_GPU C8942 Pin 1, usually i Have there 1.12.and afte gpu turn on 0.92V
Now I have there 1.22V and after turn on 1.02 V
after the software running "heaven" when the screen turn black I read on C8942 Pin1 0V
I replaced already U8900 and measured all resistors around it . found nothing.
need some help please
