    Hi, I have been having this issue for while and can figure it out. Do you think it might be a cap that might be going bad or something else? Just so I am more clear with my headline. I shut my monitor off at night then in the morning I turn it on, but what happens is that when I turn it on it goes black. I have to turn it off and back on several times before it stays on. Any thoughts as to what it could be?

    Monitors turn off because:
    They don't see or recognize a sync signal (video) They go into power down mode.
    The on/off button might be "bouncing". Dirty contacts in switch.
    Some thing is bad inside. Who knows what?
    Over current on the power supply.
    AND a million reasons that you will not have thought of.

    CRT or LCD?
