You could have a defective screen - a defective inverter or a CCFL lamp.
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:

  • 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 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.

One of those screens will provide you with an error code or a more detailed description of why it crashed. Please provide that information...

My fn key and home for making screen light bright isnt working can any one tell me is there any other way to make my screen light high???please help its so dark


You should try to determine why your Fn keys are not working... just to make certain, the Fn+Home key will increase brightness and Fn+End will decrease.

You can try the blue IBM-Access Key. In the Configure tab, you can manage the display settings.

If you cannot see your display because it is too dark, try attaching an external monitor via the vga connector.

It is stuck in a loop the screen goes from the IBM logo to a screen explaining that windows didnt start successfully to windows starting up to a blue error screen and then repeating.


You can have your T42 working again by doing the following:

1. In the windows didnt start succesfully screen choose to boot in safe mode with command prompt
2. when it starts, enter the command chkdsk (that means check disk)
3. accept all the changes done by running the command above and restart your laptop
4. everything should be OK now

Good luck!

IBM t42 Display problem


Sometimes there are keys are your laptop that adjust your settings.
If you know which keys you can hit the fn key simultaneously.
If your not sure go on line and you should be able to find a site that will tell you how to adjust your screen.
In search type your laptop model then type display settings

Laptop screen gone dark


I had a similar problem on my Fujitsu-Siemens Lifebook C-1020 and I had to replace both the C/C inverter that the CCFL lamp. Easy to find/replace the inverter (only take care of input/output plugs), tricky to find/replace the CCFL lamp (because of diameter, lenght and toxic Hg content).

Zpp
Have fun!
