Try replacing the LCD screen first. (Screens usually have a 2-5 year life span. )

What caused a black screen


I had the same problem. While rebooting the laptop the screen would be on for a few seconds after it finished rebooting then the display would go black. If you looked very carefully at the screen you could see the image was there but there was no light behind the screen to make the image visible.

I removed the black plastic display bezel cover that goes around the edge of the display screen to check out the lights and wiring. I found a small magnet that belongs inside the display bezel had fallen out of it's slot in the plastic bezel and was stuck to the inverter pcb (printed cicuit board). To fix this problem I secured the magnet into it's slot inside the display bezel with a bit of glue. After fixing the problem and putting the display bezel back together the laptop worked normally.

The magnet could possibly fall out if the laptop was closed and upside down then dropped on a hard surface. Mine did not feel very secure in the mounting slot which is why I secured it with glue.

This magnet is how the laptop knows the lid is closed. When the laptop is closed the magnet is moved closer to a magnetic switch on the inverter pcb and activates the switch. The laptop thinks it is closed and shuts off the lights behind the display screen. When the magnet fell out of it's slot and stuck to the inverter it activated the magnetic switch all the time whether the laptop was open or closed. This caused the laptop to think it was closed and shut off the lights behind the dispaly screen as soon as the reboot finished.

Black screen but i didnt hear any beeps


Dear frnd,
its looks like Operating system problem. some times its happens that you power on and its display nothing except a black screen. you need to re-install the os but before it you have to confirm that your display screen is working. for that check the display in dark place so that when you power on its screen going to slightly white if its happens than its screen is ok if its doesn't than you have to change display screen cable inside of the laptop.

My PC develop a problem of not displaying light on the screen


If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.

My dell xps laptop fluctuate sometimes, its been 1 year old...sometimes the screen fluctuate...pls help me


shajuchy19,
If the screen is fluctuating try plugging the power into a power strip. You can also try reinstalling the video card drivers to see if that will resolve the issue.

Thank You,

Left side on my laptop monitor is black, is it the monitor or the grapic card that is bad


If you have an external monitor, plug it into your laptop. If, on the external monitor, there is also graphical errors, it's your GPU, if not, then it's your display.

If you don't have one, it's a little more tricky. Generally, if it's a display issue, it will affect absolutely everything, all the time, the same way. If it's a GPU issue, you're going to see fluctuations, flickering, and just general weirdness.

The only way to tell for certain is to swap parts. Since a monitors is far easier to plug in than another GPU, that's your best bet to be sure.

Full screen fluctuation in Acer Laptop.


Sound very much like your LCD inverter might be going luckily there pretty cheap and you should be able to find one on Ebay.

An LCD (liquid-crystal display) inverter is a component in laptop computers that supplies the power to provide a backlight to the monitor, enabling the user to view what's on the screen. This component is commonly the culprit when the monitor goes out and can be moderately simple to replace.
