Monitor Black, Green Power Light Flashes Monitor is 4 yrs. old
I began having problems with my monitor about 4 months ago. I turned the monitor off and it stayed bright white and did not go black. The entire screen was a big white light!! I had to leave the monitor turned on because it lit up the entire room. Several weeks later, I tried to turn it off again, and it turned off correctly. I noticed in the top left corner, the screen was flickering. The screen display was still pretty good. It continued, so I decided to turn it off. It went off fine, but will not come back on. The green power light seems to flash 4 times, then short break, 4 times, break, etc. There is no type sound coming from the LCD. Any idea what the problem may be.

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.

well i have a dell 22'' monitor and it did exactly the same thing , turns out its a fault with the invertor drive transistors ( these power the fluro screen light ) , i'm in the uk , but i would take it straight back to walmart along with proof of purchase and tell them it dont work and ask for a repair /replacement under warranty
Try the monitor with another computer. If it works, the video circuitry (whether it is on-board or a separate adapter) in the Gateway is the problem and needs to be replaced. Otherwise, the problem is with the monitor itself. From your description it is probably the Gateway's video that is the problem since the power light on the monitor remains green indicating that it is seeng a signal, but not something it can properly interpret, i.e., one or more of the control signals are shot.
Having a similar problem. When I turn my monitor on, the picture tries to come on, but then goes black. After several times, I may get lucky and the picture will hold. Is my monitor about ready to give up the ghost? Mine is a few years old as well.
Turn down your color and see if the screen has a normal black & white screen. If it doesn't then the CRT is bad (picture tube). If it is black & White then you have a either lost your red or blue.That problem will be in your video driver circuit of which a service center can handle.
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.
Try connecting the wires properly. try changing the VGA cable. i had the same problem my screen goes black some times and pink i changed the VGA cable it was absolutely fine!!!
