Hi everyone.

I am trying to troubleshoot this computer screen which went black and won't power on after a power surge.

I have measured the output voltages and there seems to be proper voltage pressence on the 5V outputs, there is no voltage on the 22V outputs and I am unsure of what I should be measuring on ADIM, BDIM, EN and OLP.


There also doesn't seem to be any voltage on the backpanel outputs:


I have already identified and replaced two bulging electrolytic capacitors, and there is voltage after the fuse.
