monitor changes color remains blank

Specs: Windows XP
after a windows update yesterday, the other computer in our house was turned off, but today I noticed that the monitor goes from orange to white to blue and back again over and over. is the update responsible or has the monitor just died?? thank you!!
I might also add that the user of the other computer is blind; he turned on the computer last night and was able to move around in jaws as usual, no problem. He was unaware of the monitor changing colors. So perhaps the monitor just needs replacing?

If this happens while booting the computer BEFORE the operating system loads from the hard drive, that can't be caused by any software on the hard drive - that's a hardware problem.

If it's an external monitor, try it with a different computer, and/or try a different monitor with the problem computer.

If it's the built in display on a laptop computer, try it with an external monitor.

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

See response 1:

DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.

Some laptops will display on an external monitor without you having to do anything.

If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / built in display video only / sometimes both - see the Owner's or User's manual for the model.

actually, I turned off the monitor for several minutes and turned it back on; turned on the computer and it was ok.
