Try an external/different monitor, also if running windows you can try a fallback to a previous restore point. Also try the monitor on a different pc, if it's a desktop. That way, you will know if it's the video card in the pc.

Horizontal line appearing on desktop


The fault looks like white lines horizontally along the screen. These are the retrace lines that become visible due to absence of proper screen/grid voltage. You will need to open the monitor only if you are familiar with power electronics, a bit of experince is important as the stages are delicate and contains high voltage. If not take help, check for faulty capacitor or low value of resistors in the screen/grid sections of the crt. Couple across parallel to the suspected capacitor to confirm and change. Use a meter to see the voltage across faulty resistors. In some cases reducing the screen potentiometer ( onthe Line output transformer)can solve the faulty. Hope you try. Good day

My screen starts going white at the bottom and works up the screen untill all white. I turn the moniter off and on again and it works for a few minutes then does it again.


hello :-) I am guessing that its your screen's problem of what is happening not the computer's. If you want to make sure that its the screens problem look down at your computers tower ( while this white screen problem occurs)  and see if the little orange/yellow light is solid ( that represents the processor ) . If the light is solid that means that it might be the computers problem. but if it isn't solid that means its the screens problem. I would recommend trying a older screen ( you or a friend might own ) and hook that up to your computer/tower if the screen doesn't do what you are describing in your problem that means that its the screen's problem and that you need to buy a new screen.

Lines going across picture on plasma screen


Try connecting another screen (any other screen, doesn't have to be plasma) or try connecting the screen with the problem to another machine. Either way you'll eliminate one piece of hardware. Either the lines will still be there on the screen, in which case the screen is faulty and needs repairing, or they won't be in which case the problem most likely lies in the display card.

White lines going across the screen


THere are two possibilities
1. problem in mother board
2. problem in monitor

To make sure if possible connect your CPU to another monitor and see if all is fine. If the other monitor works fine, then your monitor has th problem
if the other monitor also has lines, then the mother board's video card has prob.

Also check the connection wire between the CPU and monitor that there is no loose contact or any cuts or damages in the wire

PC or monitor, signal problems


your monitor is telling you it's on it's last legs..either that or your compaq has a bad video section. either is more vital than a video cable being loose.

First things first:

2) go to CHECKPOINT recovery and select a date before you install this software. restart your OS.
3) change (if apply) the video driver, for a new one. depending if you got NVIDIA, or ATI video card.
