Having problems with your IBM ThinkPad R51 Notebook ?

Screen goes fuzzy after 45 minutes

\015 I start the computer and run it for 40 to 45 minutes and the screen goes fuzzy to the point that you cant see it anymore. I was wanting to know if it's the video card or what the problem might be.\015

Answers :

If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

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.
Check out www.lcdparts.net for parts, repair service and DIY info.
OK, it have NOTHING to do with back light!
There could be 3 things: LCD cable connector got loose, LCD cable is broken and need replacement or LCD itself needs to be replaced.
