Most likely you have a fault in the back light circuit. To verify this, turn on the set, when the screen goes black, take a bright flashlight and shine it on the screen. It may be easier to dim the lights in the room so that you can see the faint image on the screen. If you see the faint image, you indeed have a back light problem. You will need to get a diagnoses performed on the set to track down the problem

The fault could be a faulty inverter board that supplies high voltage to the CCFL lamp or the CCFL lamp is faulty. The CCFL lamp is a mini fluro lamp that provides the back lighting for the screen.

The desktop is blackscreen


When you say your desktop has a black screen does that mean after your computer boots up its black or even right when you turn it on you do not even see the the Bios screen.

I know you wrote desktop but are you just using that as a term for a a computer so Is is a laptop or desktop?

There are three possibilities,
1) Your screen died
2) Your graphics card died ( if its a desktop it usually an easy fix, if its a laptop most times its unfix-able )
3) if its a laptop can you see a very faint image? if so there is something called an inverter that can be replaced to fix that issue

The laptop turns on, but the screen stays black


If you can shine a light into the screen and faintly make out the images? Then it's probably the inverter/backlight board, not too expensive or difficult to replace in most cases. Let us know.

Screen goes black but have faint image in background


Does it boot up as bright as it used to be and then go faint or has it recently only been faint?
If it's the latter it sounds as though the lamp has gone. This can be fixed more often than not, but can be a bit expensive.
Is the laptop still under warrenty? If so go back to the manufacturer or if not you should take it into a computer shop to get a quote on fixing it.

Power comes on but the screen stay`s black dose it have a screen lock or stand by


Black screens can be caused by many things the first bit of video runs through the ram, so try changing the ram or swaping it. the next thing that causes a black screen is the LCD Inverter or the back light bulb to test this is take a flash light and shine it on the screen at an angle and see of you can make any faint images out. Next dis-assemble the laptop and see if the processor is heating up or staying cool.

Hope this helps!
