Bad lcd monitor

[westrock]

I have a Samsung p2250 lcd monitor. The monitor will only display for 1 second and then goes to black. If the monitor is powered off, and then back on, the monitor will display again for 1 second, before going to black. I'm thinking either bad caps, or inverter???

If it's still under warranty I would RMA it after testing it on another system just to be sure it really is the monitor and not the system that is blanking the monitor.

Hi westrock,

It is likely an issue of the LCD not getting the power it needs (like you suggested Caps or inverters could do this)

It would be tricky to repair this yourself. How recently did you buy this monitor? Is a return possible? If not a return, can you request an RMA from the manufacturer?

Easy enough to check for bad caps, just take it apart... but I usually see those causing 'No Power' issues.... Check warranty status first, then take it apart and check for obvious failure(blown/bulging/leaking caps)... If you can't find any visual problems with the caps(usually on the power supply) then I would just buy a new monitor. They are cheap enough, and I wouldn't want to spend time and money trying to fix an inverter/main board/back light problem.

Are you sure it's not just REALLY dim.... use a flashlight to see if you can still see picture... even if you do see picture, you will still be in the same boat though(repair wise).

The monitor is no longer on warranty so I think taking it apart and looking for bad caps is the way to go. Just stay away from the 200 volt caps, right.
