Skylink 318k remote garage door opener doesn't open door. Beeps according to the manual as it has always done but backlight no longer works. Is that the problem? Is only option to replace?


as far as the backlight, dont worry about it. You need the find the program button on the opener itself. With the door up, push the hard wired button,, on the opener, and the remote pointed to the opener, button at the same time to close. This should reset the remote..

Usually Dell monitors have a 3 year warranty, hence check with Dell. If your monitor is out of warranty this problem can be fixed by a tech who can open the monitor and replace teh backlight or the backlight circutis.

When I turn on my Akai, I sometimes get a clear picture and then it fades out I still see what I'm watching but its faded out, the people on the tv look florescent


This could be the backlight failing (most often the images will tend to go pink). If the TV is out of warranty, you can replace the backlight(s) yourself. lcdparts.net has many backlights but you need to match the length and width to the original. Next you need to open up the back of the TV and carefully remove the old backlight(s). The backlights are on the perimeter of the TV (laptop screens started with one but most TVs have several to maintain an even lighting of the image).) The removal takes some work and paying attention to how the original is put together. The backlights are often molded into the frame of the TV and a Dremel or other rotary tool is needed to get the backlight out. Google backlight replacement for videos, pictures and descriptions of the process.

I hope this helps.

My philips lcd tv has sound but no picture what is


change the backlight (cold cathode light) on your monitor.. If you are able to open the back of your lcd monitor carefully, the backlights are located at the upper and the lower part of the edge .. replace it with conventional cold cathode lights(protective tube was removed)... there are also instances that backlight was good but the ballast transformer is burnt. Replace the ballast. Its very cheap to replace that.

Dell XPS M1330 Backlight Problems


Really does sound like a backlight problem. They usually don't cost much and are easy to replace if you are good with a screwdriver.

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.

First off, on these monitors, usually the power board is also the inverter board. If its not on this model monitor, and you know that by opening it up and seeing the backlight cables connected to a different board, than that may be the problem, but it might not be.

Secondly, Why did you replace the power supply? Were you not getting anything? power light? anything at all?

If you were getting the power light, but no picture (black screen), something else was most likely the problem.

Your problem is probably the backlight. It sounds like its out. Does the backlight come on at all? If it doesn't and you can faintly see an image if you look closely or if you press the menu buttons and see a faint change in the screen, thats the problem. Normally I would say its either the power board OR the backlight, but you say you replaced the power board. You need to replace your backlight. You can do that a couple different ways:

1) Replace the whole LCD panel. This is a costly fix, so if you are adventurous and cheap like me I would advise against it.

2) Replace the backlight panel. You need a screen like yours that is broken, but has a good backlight. That way you get it cheap, because its broken and beyond taking everything apart and putting it back together again, its relatively simply.

3) Fix the backlight you have. There are tutorials on how to do this online, but its harder and more dangerous (mercury and toxins that can cause lots of damage). I wouldn't do this, but if you want to I would suggest doing it in a place with lots of ventilation.

There could possibly be a problem with your mainboard, especially if you see no image AT ALL and you don't see a backlight. If your power board/inverter and backlight are fine, you should see the backlight on, regardless of the condition of the mainboard. If you see the backlight, then the mainboard is the problem. If your power board failed, and the power light wasn't coming on before, its possible that the board fried your mainboard and potentially your backlight (although damaging your backlight is rather unlikely).

In any case, good luck to you!

Palm IIIxe backlight


No, the backlight seems to be about the first thing to go when these screens fail. You can possibly get a replacement screen from pdaparts.com.

D600 screen went very dim


You also might check to see if there is a HOTKEY setting for the brightness of the screen (usually FUNCTION or FN and then some key on the top row).

Replacing the backlight on an LCD is a very advanced and trouble prone procedure, unless you are good with soldering and taking things apart, you should probably use it with an external monitor or think about getting a new machine. :>|
