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.

IBM THINKPAD SCREEN DEAD


Hi,

Since you have replaced the inverter and the unit works with an external monitor, then probably problems would be with:
  • CCF lamps (backlight);
  • inverter triggers and/or B+ supply.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

IBM Thinkpad T20 screen problem


If it was fixed before without changing any hardware, it was probably a connection problem. Check the connectors on the screen, screen to inverter, and screen to board.

How do I find my Thinkpad 2647 cmos battery, to change it?


It is unlikely to be the cmos battery as there are signs [music] that your laptop is booting - shine a light into the screen if you can see an image but it is very dark then it is likely that the screen backlight is not working. If this is the case the most likely causes are a faulty inverter or a faulty screen cable - both can be obtained as a kit quite cheaply on ebay if you have the ability to fit them.
