Monitor flickers but does not turn on - Computer Monitors
Possibly the caps in power supply. There are about 4 to 6 caps that maybe bad. Look for the top of the cap to be bulging. If they are 16v go to 25v. if they are 25 go to 35v. use the same ufd's. sometimes they under rate these cap's. Can't take that off and on surge all the time. Make sure you put them in the right way and not backwards. Hope this helps.
Try a known good video card and/or try the monitor on a friends computer
