    Samsung 204bw problems

    hi i just picked up a 204bw works fine on VGA but put it in DVI and it works fine for a minute or two then small pixals start flicking on parts of the display untell the screen goes black, then it comes back again and goes black again rinse and repeat. i suspect maybe caps, it looks to have been opened before, but since its only doing it on dvi and not vga its probably not the power supply i would think.

        You lift up the front bezel at the top center then slowly and carefully work you way around with flat plastic or wooden tool but do not lift the bezel off completely. Put it face down on soft surface then snap back the back cover.
