Just an update. I replace some caps on the PS, and that seemed to work. I ran some pretty long tests on it with the replacement caps. Then after a long (over a few hours) test I came back to a monitor that was going from White to black, with shades of grey. Couldn't power off with the power button, had to unplug. Then could not get to power back on. I have to wait over 10 mins or so to get it power up. Now the monitor screen will not remained power for more then 10 to 15 mins. And now the PS is making a high pitch buzz sound close to the transformers.

What could be the problem? what should i look at?

If U have replaced the caps. Then U need to check for Voltages and find out which area is shutting down. Unless U do what I say I cannot show u where or how to check it.

Individual component checking is hard beside replacing new caps.

I cannot tell u what to do as what shud be done cause it only comes to my mind after me looking at it
