Use a flahlight see if you can see an image faintly in the screen, if so the backlight is failing. if not, check your VGA or DVI cable connection on both ends. sometimes there is more than one port on the back of the computer, try the other port if you have two of them,

Our compaq monitor will not go on. It is plugged in and the green light goes on when the button is pushed, but nothing comes up on the screen after moving the mouse. Our Presario computer is turned on. Any...


Make sure it is properly plugged into your computer too. (blue headed cord) should go from the screen to the computer. Make sure the cord is not damaged.

There should be a total of two cords needed (one for power (black) and (one from the computer to screen (usually blue))

Monitor goes blank less than a second after turning on.


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.

Black screen


How old is the computer? Make sure that the power light comes onto the monitor when you plug it in, should be orange and then turn green when video card syncs with it when PC is turned on. If you are getting black screen when PC is powered on:
1. Bad video card
2. Bad video cable
3. Bad monitor
1Solution: Try using a different monitor attached to this same PC and see if it works. If it does, then its the monitor, its cable, or its power supply. If it doesn't work, then its the video card or the video cable coming from monitor.
