Hi everyone
i have 3 motherboards acer 8930g with the same symptom,
they power on but there is no display on the screen, internal or external
i have replaced the graphics card, cpu, ram and cmos battery,
i am testing the boards naked on the bench
the part number is 8930G 6050A2207701-MB-A02 and i have downloaded the
schematic which can be found here
https://cdn.badcaps-static.com/pdfs/...e16bb74757.pdf
Now what i have seen is that the mxm connector is missing some voltages
(5V in pin 8 which is the power for the card i believe), i tried to give it power
bridging with a capacitor and now the card is getting warmer but still no
display
any help to pinpoint the fault would be highly appreciated,
regards
