Monitor can't wake up from sleep mode

Newbie here...I have a Dell 17-inch flat panel display that I run with Windows XP. It's just over three years old. Recently we've had trouble regaining an image on the monitor after it goes into sleep mode.

The monitor's power button remains green, but blinks on and off. You can see an image for a fraction of a second on the monitor as the power button blinks, but then the screen goes dark again. The computer seems to be booting up normally. I have to keep pushing the monitor's power button off and on to get a picture. Once I do this, the picture is as clear as always...no blurs, etc.

I've checked and re-inserted the monitor cables and they seem okay. Could this be a video card issue, or something else?

Thanks in advance for any insights you can provide.

Try the monitor on another computer.
If it behaves in exactly the same way, replace the monitor.
