Question about Toshiba Satellite A105-S4004 Notebook
I have had a video problem with my Toshiba A105 for about a year now. The first time it happened my laptop slid off the couch and landed on the ground on its side. After this incident the LCD would not work even though it would power on. I took it for repairs and they said a wire came loose. So after that it was fine. But one day I was working on it and the screen flickered. I then adjusted the angle of the screen back and forth and it stopped flickering. But soon after it went out completely. Now the funny thing is i can connect my laptop to a desktop monitor and it will work fine. So I Im sure its a connectivity problem. This has led me to believe the same thing happened as before. A loose wire. Ive been looking for a way to solve the problem without having to replace the LCD...and thats what Im trying to avoid. I already open the case of LCD, and I try to unplug all socket and clean it up then plug it again, it's work, but the colour is becomes flikcer
You most likely have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :-
To determine if you have a LCD screen or video card problem, read this and follow the instructions.
Defective CCFL backlight, it may have the following symptom:
Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
