LCD monitor will not stay on

Hello, I have a Hyundai L70S 17" LCD monitor and just recently it stopped working. What happens is that the monitor will simply not stay on. While I was typing my term paper the monitor suddenly shut off (power light and picture), then the power light comes back up for about 5-10 seconds with no picture on the monitor (black screen), then the screen flashes for a fraction of a second and the whole process repeats. While this is happening the power button is unresponsive. I've pushed the button throughout every phase of this cycle and nothing happens. The only way to turn it off is to unplug the power source.

I've already switched out the cords so I know it's not that. I've also switched out the monitor so it's not the video card either. With just the power cord plugged into the monitor the same cycle of off-on happens with the LCD test screen as well, so I'm 100% certain it's a problem with the hardware of the monitor.

I'd like to know what you guys think to see if I have to take it into a shop or not.

When you swapped the monitor, you didn't have this problem anymore? How long did you leave the "swapped" monitor attached? If it is not the video card, it has to be the monitor...especially since you can't power back the monitor w/o unplugging it.

If you can, try the monitor in question on a different PC; if you get that problem again, you know it needs to be returned or exchanged. Good luck, hope this helps.
