LCD Monitor shows display for a split second when you turn it on but nothing beyond that

Hello,
    I inherited a dell 17" flat panel monitor when it died out of warranty on one of my clients. I took it in figuring I could maybe repair it and keep it for myself. I checked the pins on the cable, replaced the power cord, and as far as I can tell it's maybe something to do with the power supply inside the monitor not being able to provide a constant display. When I first power on the monitor it'll display signal from the computer for a split second correctly before it goes into a cylce of turning off, waiting a second, and flashing on for a brief moment and abruptly and immediately turning back off and repeat. When it begins cycling on/off there is no display, but you can see the screen flash with a little light each time the power cycles. Anyone experienced in lcd repair know what this usually means?

Some of the most common failures in LCDs are the backlight and the inverter board that powers it.  See

It sounds like a bad capacitor in the power distribution.

Does the LCD allways act that way or only when the PC's OS is up? On booting, can you see the BIOS screen or doesn it cycle there already?
