Google BAD CAPS and then open it up to inspect for them. Replace all blown units, tilters, leakers and dome tops.
The symptom is consistent with this part failure.

I have a Dell E153FP LCD monitor and when I start using my computer after being away from it for several hours (like overnight) the monitor display goes away (black). Power indicator is green so I power off the monitor and then power on monitor and all is good for several seconds and then the same thing happens again. After 5 or six times of doing this dance the monitor will work fine. Problem has stopped. Have tried monitor on 2 computers and have same problem. Your help is appreciated.
