I received a power colour Hd7950 3Gb GPU.
Diagnostic card stuck at b2 and cannot cross it. So not output screen.
On board graphics also do not have output.
I measure all the voltages, the core gpu ( I forgot is technical name) voltage rise and fall to 0V. the rest of the voltages are fine.
How to troubleshoot this type of problem. the PWM chip is working and enable voltage is there , so that is why there is a rise in voltage.
