Flat Panel only turns on for a second

[techdude007]

I have a Princeton 17" flat panel monitor and when i turn it on, it will turn on for about a second then turn off. If I turn it off then back on, it will do the same thing.

The only thing I can think of is the VGA cord I bought for it didnt come with one of the metal prongs. See picture for reference.
(circled in red) could that be it?

nm it's not the cord.. just tried another one i had that has all the prongs and still has the problem.

Does it do this whether or not it's hooked up to the computer?

does it turn off completley or just go in to power save (orange) mode and this computer is it in windows/can you hear the sounds from windows as it boots up/does it work with a different monitor

It goes into the power save mode, and I dont have the computer hooked up to speakers so I don't know if it's making any sound. And yes, it works with my other flat panel monitor.

then it sounds like a bad monitor either the connector/powersupply/something is bad...i wouldnt know how to fix this or advise anyone to do so even thou i dont think lcds are as dangerous as crts but if it is still underwarranty send it back to the plant for repair/replacement

yeah, it's just weird how it turns on for a second though. you would think if it was one of those things that it wouldn't turn on at all.

well if its the power supply i can see how it would peak for a second then become insufficent...there might be an eplanation for other things but i cant think of them off the top of my head

Does it have an internal p/s or a brick type powersupply?

Maybe if its a brick you can easily multimeter measure the output---possibly eliminating it as a prob...
