Question about Toshiba Computers & Internet
My brightness is very low. I can't see anything . I'm running windows Vista. Yeterday I had a crash so I shut down and restarted my machine. Everything was working fine. Then I hibernated my system. When I tried to come out of hibernation, I can hardly see the screen.
Tried shutting down, removing the batter and then reinstalling and restarting my system with no luck.
I tried pressing FN and F7 to increase brightness with no success.
This could be a faulty CCFL lamp.
To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, 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.
