I recently broke the lcd screen in my laptop and bought a new one online. When I turn my laptop on it seems alright then I notice that the image is bright but almost too bright, then a noise is audible and when the brightness is adjusted the noise will change pitch. After a few minutes the screen starts flickering and eventually just goes dim where the image is barely visible. I can swap out the new screen for the old one and besides the giant crack on one side of the screen, there is no noise, heat, flickering, or dimming and it works fine so I don’t think its a problem with the inverter board. Everything is fine when it is connected to an external crt monitor. If anyone has had a similar experience and resolved the issue, I’d like to hear how. Thanks

a quick question:

is that any way we can confirm the problem was CCFL or caused by defective inverter ? Thanks

One quick note, the voltage is a large consideration on these CCFL tubes. If you can find out the voltage you will have a much greater success with your project. *caution* these are operating at several thousand volts on start up, make sure to unground yourself lest the worst should happen.. nobody likes the smell of burnt hair.

Just thought I would add you have to be careful not to apply a lot of pressure to the screen, an LCD has many layers to the screen, and the portion that actually shows color is very sensitive to pressure and can be damaged easily. I tried replacing the CCFL and wound up having to replace the entire screen because I damaged the main part of the screen and when that part gets damaged anywhere, the entire screen fails and has to be replaced. Curiosity killed the cat as they say.

I am not what you call a “computer wiz” but these instructions are very readable , understandable and it make what I always thought to be “the imposible mission” into something that can be done. Many thanks to you for helping save a few hundred in a new lap top!

Though I wouldn’t try this as a first project with the soldering gun, these directions provide an inexpensive way for an amature/self-taught electrician to repair a dead LCD screen. I have not attempted to solder on a new CCFL before, but I have replaced entire screens from spare parts of identical laptop models, and I feel confident that I could make such a repair in the future after reading this article.
