Hi Guys,
Newbie here to board repair so bare with me. I have a bunch of Socket 775 motherboards from arcade gaming machines. The brand is DFI, and it's their industrial motherboard range model number G7L330-B
All boards have the same issue, no POST. I've re-capped the boards completely, can't see any shorts across the 12V rail and I've removed all MOSFETS from the board to test them. The boards have been ultrasonic cleaned as well as an alcohol bath, doesn't seem to have made a difference
BIOS is also correct, I do have a working board for reference...
