Monitor goes blank less than a second after turning on.

could be hardware failure but i would try buttons on front of monitor first. notice, usually green led on monitor is green, if it goes to amber, you are loosing sync pulse.

Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

If you put a spare monitor on your computer and everything is fine I'd say it has an electronic problem. If the screen is still blank I would look at the video card or PC itself as the problem. Just for fun check the video cable for bent or missing pins.

Monitor is bad for sure. Try another known good monitor on your computer and if the problem stops then you know for sure the original monitor is bad. Hope this helps.

there is an hardware issue in your lcd it needs to change one of the capaciter please take it to a lcd technician
thanks

the moniter may be having  some technical errors   maybe the IC's has got corrupt 

you need to call the seller of the moniter

do you have an aftermarket video card. In the bios you have to tell the computer if it is looking for a agp/onboard or PCI video card. Either that or the video driver or settings are wrong Try safe mode to check

Beautiful screen, lasts about for a few minutes, goes black. Power button still green. If I turn it off, and then back on, it works again for a while. Any ideas?

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.
