This monitor will come on, work well for 15 minutes to a couple of hours, then the display will flash on/off about once a second. It shows "Dell" on the screen when it is in the on cycle, not the computer image that was being displayed before the cycle began. The power led also flashes on/off with the display, and the power button has no effect. It will continue to flash until I remove the power cord. Once I reconnected the power cord a few minutes later and this time it just gave a very brief flash, no power led or anything else...

The symptoms suggest the video processor (the Genesis chip at the right side of the board) is being reset. This MAY be due to power supply fluctuations.
I've marked three voltage regulators (I think) with the numbers 1, 2, and 3. What are the part numbers of these three regulators? If you can locate the datasheets for them, you can anticipate my next question by telling me what the output voltages are when the monitor is working, and when it fails.
In the last photo you can see the caps I replaced - they have yellow lines by them. I used LXZ or Nichelon new caps.
