Greetings, having some trouble with this board, it presents with no video I checked voltages at connector I found +3V rail is only at 1.8v however I've been unsuccessful in locating boardview and schematic for this board and I'm not very familiar with HP boards so not really sure where to go with it atm, +3VS5 appears to be fine so I'm going on the assumption that the issue is with the mosfet or driver ic but without boardview I'm having trouble locating them.

Any assistance would be greatly appreciated!
