I have had the same problem, but noticed something while moving cables. When I tap on the side of the screen, near the control buttons, it fixes it. You know like in the old days when your tv wasn't working, a good bang on the side of it got it working again?\012:)\012Anyway, that tells me it is a loose connection problem, internally, and not a heat problem. I will have to open the thing up to get more detail. Not today.
I ficxed this problem today and what it was in my case was two 100uf 6.3v capacitors on the logic/main board. These are the two capacitors on the 5 volt side of that main board and were failing. No visual signs of a problem but pulled them off the board and tested them with ESR meter and they were faulty. The day before I repaired the power supply on this monitor and worked great but was turning black and coming back on and I noticed there were artifacts bleeding through the screen at different places as the monitor stayed on. Please dont think Radio Shack is going to have the caps to fix this one. If anyone needs any advice on ordering these two caps i would be happy to help.
