Monitor flashes on the desktop then turns black. Must turn off and on several times (up to 10 times) before it finally stays on. Have always been able to get it to turn on and it behaves properly after that. Afraid this is the beginning of a major problem. This flat screen has been trouble free since purchase about 4 years ago.
Also, I can't seem to get to the Sys site. Surely there is one. The manual that came with it is all but worthless, save for basic instructions.
Thanks for ANY advise you can send. VMM
Possibly a capacitor on the internal board for the monitor that will not stay energized to allow the backlight for the monitor to illuminate. Going to need a qualified technician with the tools and equipment to diagnose it first hand. If you are not sentimentally attached to the unit, you can pick 17" monitors up pretty cheap these days.

Sound like your display is having issues with the inverter board. When the power supply detects a short circuit, it turn off by itself. When you try several times, you may be able to "bypass" the circuit protection but the damaged parts still having problems. This issue may be related with the DELL display issues.
The display needs to be fixed by someone with experience in electronics repair.
HP's are known for bad capacitors in the power supply.
Replacing them is simple if you know how..not so simple if you don't.
Try your local TV repair centre. It should not cost alot to have the capacitors replaced.
I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up? I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.
Assuming you've already checked your driver and system settings, tried a different monitor, and checked the cable and connector pins, this would almost certainly be a problem with the power or signal circuit board inside the monitor.
