    SyncMaster 225BW Intermittent blackout

    Hello

    My SyncMaster 225BW as an intermittent problem

    After few hour, the screen go black for few second then image return.

    Other time, image won't return, I need to use the power switch for an off-on cycle, then image return. When this occur, the blue power led will stay on, but pressing on the power button has no effect at all. Screen is frozen.

    Also last night I had strange color in the lower half of the screen. Color was changed, but the definition was fine.

    I had changed some capacitors, but problem remain.

    Any idea?

    When the screen blacks out, can you see it glowing in a dark room, or does it go completely out?

        MacBook Pro 15" 2010 820-2850 intermittent charging
        by protocold
        I would like to get some help on a 820-2850 logic board with intermittent charging problem. Sometimes the battery will charge all the way and sometimes magsafe would be cycling between green and orange.

        I have already tried replacing dc-in board, swapping good battery, swapping genuine 85w chargers. None of that helps..

        when it is not intermittent:
        PPVBAT_G3H_CHGR_R is 12.07v

        when it is intermittent:
        When the light is green, PPVBAT_G3H_CHGR_R is 12.99v
        when the light is orange, PPVBAT_G3H_CHGR_R is 11.62v

        data line on the battery...

        Samsung Syncmaster 740BF repair
        by soopacrucial
        Hi folks,

        I'm new here and was wondering whether you might be kind enough to give me some advice on troubleshooting the following problem:

        Quite a few years ago now, a couple of years from new, my Samsung Syncmaster 740BF LCD monitor starting playing up by making a buzzing noise and then the display would go blank. I seem to remember the blue power led would also go off when this happened but that I'm not 100% sure of. By pressing the power button I do remember I could at first get it working again but eventually the problem would come back. At the time I had read about...
