    I went to do dishes, and came back my monitor(ViewSonic) was turning itself on and off, the light would come on, display my desk top for a fraction of a second, then the light would go out for a couple seconds. I tried turning it on and off a couple times (I can turn it off and it will stay off, but not on) Unplugging it and what not, to no avail.

    I immediately thought it to be my monitor so I lugged an old monitor (Samsung) out and tried that, but it did the same with that monitor. Then I thought maybe it's just the computer, so I plugged the ViewSonic into my old computer and it continued to flash. (The Samsung works fine on my old computer, using that at this very moment.) I've tried using difrent cables from both monitors to both computers with no diferance in results, power and video cords.

    All this random information may be confusing so I'll try to simplify things.

    I can plug the ViewSonic into *just* power, and it will flash.

    If I plug the Samsung into *just* power it comes up and says no connection (or somthing very similar.)

    BUT as soon as I plug the video cable into my newer computer the Samsung will start to turn off and on, like the ViewSonic.

    If there are any questions I will try to answer them, my information about my newer computer is very limited due to having no monitor to easly check it's wares.

    This is enough to tell me your problem is in the monitor.

    You don't give any specifications on your monitor or computer. Is the monitor a CRT or LCD?

    The ViewSonic is a VX924 LCD and the Samsung is a SyncMaster 955df.

    An LCD flashing on-off-on-off-on usually means a bad inverter. This is a replacable part but usually not cost effective unless it is either in warranty or you do it yourself.

    Is the SyncMaster also an LCD?

    No it is not.

    The thing that bothers me is when I plug the Samsung into my newer computer the monitor starts to turn off and on, but works fine on my old computer.

    Update: The ViewSonic is toast. But that still leaves me with my newer computer unable to be used because it makes my Samsung turn off and on like my ViewSonic did. Arrggg, frustrating!

    Sounds like there is something violently wrong with newer computer and it is blowing monitors. Possibly a short or bad video card that needs replacing.

    Such is as I feared, I'll simply send it in to the manufacturer. Thanks anyways. =)
