The screen after sometimes will off by itself. Power off and power on, the screen will come back. It will power off again and i need to do a few times before the wcreen will be back to normal. what could be the cause? I think it is the video unit that may have problem, but which component can cause it?
I am assuming this is on a desktop and not a laptop. Might be an overheat issue. If it runs for a certain amount of time then shuts off, that is a tell-tale sign of overheating of some critical component inside. So, either something is making it overheat, or the component is weak enough that it is unstable in the environment it is in.

sounds like an overheating problem. you can try blowing out the back of the monitor, or putting a fan close to it. If it is really dirty it will shut itself off so as to not get damaged. is it crt, or lcd?
Try replacin a new display card. If it is fine working.ok
If not try fixing for cold solder in the video section.
I suggest video section according your report the light green LED lighted that shows the power section is doing fine.
If it's working fine in DOS, it can only be your display drivers for your operating system. What happes when you start in SAFE MODE? When you PC starts, keep pressing the F8 key, go to Safe Mode. If it works, bring the Resolution down to 800 X 600 and load the new display card drivers. Restart, should be fine.
I have a philips 19 lcd. the damn thing just display a white screen with the word aging in red in the certer. it goes off after a while, turn black a while then comes back again, with the white screen. keeps doing it over and over.
anybody have any idea? i tried caps, but all the caps look good. to be noted i didnt change all.
Sorry not a solution - but I have started experiencing the exact same problem over the last month although sometimes, on switching on again, it will run for 10-15 minutes before the problem re-emerges. Initially I put it down to the v. hot weather in July but it still continues.
So I would also appreciate any solutions!
