Hi, Problem: black monitor. No visibility. MSI manufactured motherboard for Medion pc, onboard video. 1) swapped in a known working monitor. No result. 2) put known working video card in a pci slot hoping compute would bypass the onboard vid. No result. 3) tested power supply voltages at the mainboard 4 wire connector to power supply (found black ground, 12v, 5v, and I forgot the other voltage we found. 4) we do not have a pinout map for voltages at monitor cable-to-pc connection, but we could test pinouts if we had that. 5) computer sat on overnight. On reboot next day monitor went black, disk drive seems to spin up properly just listening to it.
QUESTIONS: We are just poking around. Do you have any ideas what could be depriving us of monitor display?
Thank you.
