IBM Thinkpad T23 - unable to get external monitor to work

Unable to get external monitor to work after doing so successfully for years. When I hit F7 the lcd goes black, but there is no picture on my external monitor.
1. How do I determine if this port is burned?
2. If it is burned can it be repaired?

    I have tried with both a direct connection and using my docking station, not likely that pins are the problem.

    Could this connection get shorted on the motherboard itself, rendering it inoperable regardless of the connection quality?

    what is may happening is the internal conector pins from your computer may be broken or the conector base on the motherboard

How do i switch to external monitor


Virtually all IBM and Lenovo ThinkPad and ThinkCenter laptops allow you to hook up an additional monitor or projector to the computer. When you add an external monitor or projector to your notebook, you can choose to view the display on the computer, on the external device, or on both the laptop and the external monitor or projector at the same time. Toggling between viewing devices is as simple as pressing a couple of keys on the keyboard.

Shut down the laptop. Plug the VGA monitor cable from the external monitor or projector into the blue VGA port on the back of the computer. Turn on the external monitor or projector first, and then the Lenovo laptop. Allow the notebook to boot into Windows normally. Press the "Fn" and "F7" keys at the same time to switch the display from the laptop to the external monitor or projector. Press the "Fn" and "F7" keys again to enable the display on both the laptop and the external display device. Press the "Fn" and "F7" keys again to display screen contents only on the laptop LCD. choose support you need http://www-307.ibm.com/pc/support/site.wss/MIGR-54305.html http://www-307.ibm.com/pc/support/site.wss/MIGR-4YQHUC.html enable tv out on thinkpad http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-58625

My IBM Thinkpad screen has gone dark but I can still see a bit. Is there a key to brighten the screen?


Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp

How to connect external monitor in ibm type 2658


Most laptops have a blue external 15pin video connector. Connect an external monitor's video cable to this port, then power up the external monitor first then boot up the ThinkPad, the video information will automatically divert to the external monitor first.
You can toggle/cycle the laptop and external monitor so they display on both the laptop and external monitor or the laptop LCD screen or external monitor by pressing the blue Fn key and then the F7 key several times.

T23 Ibm laptop no video


Hello !

Test with an external monitor. If it works, it is the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim on you rather than a slow degradation the inverter would be indicated.

Hope this helps.

Can i connect a presario v3500 laptop to an external momitor. @I think the display inverter is gone and i need to get some files off the lap top for work.


Yes, connect the external monitor to the port it corresponds on the laptop, usually the blue port. When you boot the computer hit the FN key located on the bottom right hand side of your keyboard and the LCD/CRT key i believe this will be the F4 key located on the top part of your keyboard this should activate the external monitor.

No visual display


Function F7 will enable the external video monitor connection and will toggle between the screen, the screen plus external monitor, and the external monitor only. Try hitting function F7 and see if that helps. Also there is a small switch that is activated when you close hte lid to turn off the display when the lid is closed. make sure that this little switch is not stuck.
