Your LCD inverter has gone bad. They are relatively cheap and easy to replace. CLICK HERE to go to a page to see what it is and the price. With the laptop open look at the frame, or "bezel" around the edge of the screen. There are usually 6 or 8 screws (depending on the model) that attach it to the lid. The inverter is in the middle on the bottom of the LCD. You can access it by removing the bottom half of the screws and carefully pull the bezel out and away. (you may need to take all screws out and remove the bezel completely) The inverter is held on by 1 or 2 screws and plugs in at both ends. Just unplug, remove, and replace. Very easy to do.

Hi,

Seems like the backlight of your LCD is already failing, you need to replace it.

Hope this helps.

I have sound on my tv but no picture


This sounds like the back-lights have quit working. This is made up with an inverter (ballast) and fluorescent lamps. I want you to try something. In a very dark room turn the tv on and watch what happens to the screen. There is three things that can happen. first the screen will stay completely black. This means the inverter never fired, and this is usually a failed inverter, but sometimes the power supply may fail. there is also a rare time the main module never outputted the signal to activate the inverter, but this is rare because you can hear the audio. So obviously the main is working at least 90%. The second thing that can happen is the screen will light for a split second then go black. This usually means that you have a bad lamp. These lamps are physically locate inside the LCD panel, and the replacement cost exceeds the price of a new unit. You may even see a dark area in the screen. The slight glow will not be uniformly lit through out the screen. Finally the last thing you may see is the screen has a slight glow. This means the back-lights work, but the video portion isn't showing. This usually means the driver board (T-con) has failed. This is probably not available separately, so you must replace the panel to fix it. And like before, the replacement cost exceeds the price of a new unit. One more thing to do when the set is on and in the very dark room if the screen is black, point a very intense flashlight into the screen. Put the flashlight against the lcd screen and see that you have video moving around the glow of the flashlight.

Screen keeps t going blank but still have power


It may be the internal backlight that is failing. When the display has failed but still has power, take a flashlight and hold it close to the screen, move the flashlight all around the screen and check if you can see anything. The display will be dark, but you should be able to make out the image that is there with the flashlight technique. If you can see an image on-screen, then your backlight has failed and you will need to replace the monitor. Weather or not you see an image is not a critical issue, but a tool to verify if the backlight is off or some other issue is causing the problem.
Note, it may be difficult to detect an image on the un-light display, for example if you have a dark image as your desktop background. So make sure to fully scan your display (top to bottom, and left to right covering the entire screen) with the flashlight technique in order to see any image on-screen.
