Re: My monitor works for a little while, then goes black.
Your power-inverter board needs an overhaul.
Probably in need of the standard capacitor replacement.
a bulb in the screen is bad (a bad bulb will usually show symptoms)
It will flicker, or will look pinkishish for a bit or dark in the middle top or bottom of the screen.

It's normal behaviour - it blinks because during boot the pc starts with the default VGA driver, then unloads it (the monitor shuts down as the video card is disabled) then load the appropriate video driver (the monitor starts up again as the video card is activated properly).
first off check all the chords and make sure the monitor is turned on. as you have probably done this try to use a different monitor. borrow one for an hour or something. if the second monitor is black as well it is your video card in your PC and you will have to replace it. If it boots as normal that of coarse means that your Xerox monitor is broken and needs to be replaced/repaired. Hope your warranty is still good. Good Luck.
I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.
My sister's monitor wont turn on at all. She was shutting her system down due to a storm rolling in, and it said windows shutting down installing updates, while she is shutting it down. She turned it on today and the little light came on then it went off and hasn't been on since then. The Tower works fine but the monitor isnt turning on at all. What should she do? She has had the monitor at least 2 years no more then 2 1/2 years! And it is a LG Flatron 20". HELP
Sorry to have to tell you this, but this is common in LCD monitors. The reason that it is going black when it boots is for one of two reasons. You either have a bad power supply that powers your LCD or your LCD's backlight is blown. These can be repaired or you can purchase a new one. But if it goes black 9 times out of 10 is because the backlight is bad. These can be repaired!
try booting the computer in safemode you can do this by pressing f8 continuously when the computer is booting until a menu comes up select safemode. If this is unsuccessful then the monitor has a physical issue.
