There are a couple of Cold Cathode Fluorescent Lamp tubes behind the screen. They have probably reached the end of life. (If you had no flickering, I would suspect a failed inverter.)

Replacement requires disassembling the display housing, then removing a screw from the side of the display next to where the fat pink and white wires go in. On most displays, you can then slide the tubes and their reflector out of the display by pulling on the wires. Be very careful - the CCFL tubes are long, skinny, and very fragile, and they contain mercury. Tubes usually come bare, with short wire leads at each end. Soldering the old wires onto the new tubes is a delicate task best reserved for experts. Alternatively, you can buy replacement tubes with wires already attached for an extra $8 each. See this tech support link at LCD Parts for more details.

It sounds like your LCD Backlight has burned out. You will most likely need to replace your LCD Screen, since you can still see a faint image.

Audio really does not matter here---in a very dark room shine a flashlight at the screen with set on to see if you see a very dim image on the screen or not.

Monitor has power. Will come on very briefly and the go to black screen. Can turn power off and back on and get the same above result.After a 2-3 hour period may come to life...may not.


It appears as if the monitor's back lighting is failing. To test the theory, take a bright flashlight and shine it on the lcd monitor screen when it goes black. If you can see the images that were on the screen before it went dark while shining the flashlight on the screen, then the back lighting is failing. Depending on the monitor, it could have florescent or L.E.D. back lighting, but it's usually more economical to simply replace the monitor with a new better performing monitor, than to attempt repairing the back lighting on the failing monitor.

Had my monitor for four years, great performance


jlallen54, When lcd panel goes to a dark condition please shine a bright flashlight 1 inch from screen an tell me if screen data is still displayed during this "blackout" condition. It might be just a single (1) poor and now thermally intermittant solder connection on the printed circuit board inside the monitor. Do some reading first and then you will understand the problem that your monitor has. 12fixlouie

The Screen is Dark and Cannot be Bright by the Brightness Keys. It Flickers when it first comes on but goes Dark. Can see it if you shine a Flashlight on the Screen. Also the Lid Switch if you Press that...


Assuming all of the connections are secure this is most likely due to a failing LCD inverter which is basically the backlight of the screen. If it's less than a year old cash in on the manufacturer's warranty. If it's not you might as well buy a new one. Hope this helps.

Monitor is Flickering and screen becomes pink


Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After it goes back to white, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. I used to check my LCD monitor and could see window image using flashlight and found out that Some of CCFL lamps inside were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
Thank you,

This is the way how to examine where the problem is. If the screen is going dark. You have to check that you can see the image on screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons (Power on both cpu and monitor), there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken. If you cannot see any icon on the screen. I would say that there are some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or dark spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
