When you say ?it turns on fine? I?m assuming that the power and hard drive LEDs turn on. If that is the case it could be your LCD backlight giving you problems. With the computer on and the monitor power LED green shine a flashlight in the lower left hand corner of your screen. Look for the ?Start? button, if your backlight is not working you?ll see a faint ?start? button if you look closely. This is usually an economically repairable problem but not for the typical home user. Let us know if you have any other questions and please don?t forget to rate this posting.

    Sounds like there is more involved than just a backlight issue. You were wise to refer it back to the seller so as to not void the warranty.

SOURCE: Laptop screen goes black, no backlite

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.

Blank screen when turned on.sound is fine though.when i use external monitor it works on the external monitor.


Hi. I have 2 units of T23, 1 unit T22 and T30. All of them has the same problem as yours. 3 units has bad inverter and the other 1 has bad CFL. Inverters can be replaced but if you have bad CFL, it is better to replace LCD screen. If your problem is CFL, you will be able to see a very faint image on your LCD screen. If the LCD is completely black and you can't see anything, then it is an inverter problem.

Inverter is located below the LCD screen. You need to remove the LCD face plate to access the inverter. Please click here for the step-by-step instruction how to access the inverter or replace the LCD screen. Inverter and LCD are available at ebay.

Note: T23 has thin plastic parts that can be easily broken when disassembling.

Good Luck. Let me know further.

Black screen


I think its the problem caused due to the cleaning. The TFT monitors are created by a array of minute display units which can be easily damaged if pressure is applied on them. Try connecting the screen to a different source to confirm its not a problem with the system. Once confirmed that the screen is damaged, you may have to buy a new one as there is virtualy that can be done to repair it.

No visual display


It sounds like your graphics card is shot. If your graphics card is a dedicated graphics card, you might be able to get it fixed/replaced; if it is embedded, then you are probably going to have to buy a whole new display screen.

My IBM T23 Laptop screen keeps going off (hibernating or sleeping?)


What operating system you running? I assume XP. If you go to start > settings > control panel > Power options (I think). You can change the options on how long before the screen turns off and stuff in there. For the other problem just right click on your desktop, and click "Properties". Adjust the screen resolution there.
