Question about ViewSonic VG800 18" LCD Monitor
Without having it in front of me to test it's tough to tell. Sounds like a power supply problem, the shotgun approach would be to just replace all the electrolytics and see if that fixes the issue starting with the ones closest to the power input.
This is a VG800 right? Because the power supply and video boards are integrated on the monitor, so you can't really narrow it down between the power or video side of the board (you can unplug the inverter, but it sounds like you've already tried that). Since the power button is just a soft start button (the monitor always has power once it's been plugged in) you can try troubleshooting the parts of the board that are constantly energized and figure out where the power is switched on by the soft switch, that may be helpful.
