Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubles hooted. Contact any service technician. The circuit will differ with models and versions.

My sansa clip will play music but the screen will not light up;


Hello,

There's a timer for the display backlight that can be set and used for
saving power. When leaving the player untouched for a certain time, the backlight switches off. Touching any button will turn on the backlight, restarting the timer.

To set the backlight timer on the Sansa Clip,
execute the following steps:
1. Press Menu button to return to the Main Menu.
2. Move to Settings and select it.
3. Select Display.
4. Select Backlight.
5. Press |<< or >>| button to select desired backlight timer.

Screen is to dark. cannot see letters very well.


Suggest you press the Fn key And the key to increase brightness, first. (Should be a key that has a sun icon on it)

Barring this does not increase the visibility of your LCD screen, the I suggest the Backlight is bad, or the Inverter.

The Backlight is a type of CCFL tube (Cold Cathode Fluorescent Lamp) mounted to the LCD screen. The LCD screen needs the light given off of the Backlight.

Replacing the Backlight is a daunting task, and if done wrong, will cause possible damage to the LCD screen.

The LCD screen itself has a thin metal frame holding the components of the LCD screen together. This frame must usually be opened on the side that has the backlight, to access the backlight. The components that make up an LCD screen are fragile, and can easily be damaged.

The Inverter supplies power to the LCD screen, as well as the Backlight.
Inverters do go bad, but commonly it's the Backlight to go first.

This shows a typical Backlight replacement. It IS not an advertisement to attempt this yourself, but a reference tool for information.

HP Pavillion F1503 screen has gone dark...background is very, very faint, barely able to see/read it. What is the problem? If it is a ''backlight'', then what exact is a backlight, what does it do, is it...


Most of the time in this situation, the problem is due to the backlight going out. However, there are some instances where the inverter cable is bad.

The backlight is the part of the LCD which illuminates the screen. Think of an LCD as having multiple layers. One layer has the image itself on a semi-transparent layer and then behind that layer rests the backlight (usually a florescent bulb) which shines through all other layers to make the image glow and illuminate.

More info can be found here:

http://en.wikipedia.org/wiki/Backlight

As far as replacing the backlight, I always replace the whole LCD itself, which includes the backlight.

Otherwise, you risk ordering the backlight and finding out that it was the connection from the backlight to the LCD that was causing the problem (very possible) and then you would have to order the LCD anyway.

My backlight is broken (Casio EX-Z100)


Try to check on ebay, you may find the LCD with backlight just less than 30 bucks. To replace the LCD kit is easier to replace only backlight, and it's hard to find the backlight.

Backlight is off


You either have a bad LCD or bad backlight board. The backlight on your screen is no different than a light bulb. If it burn out it stops working, if these is no power to the backlight your screen will have an image but no backlight to see the image.
