Question about IBM ThinkPad T23 2647 Notebook

1 Answer

No LCD video, but VGA video

I have an IBM thinkpad that came to me with no video output at all. Changed the motherboard to solve the problem, but notebook only gives video from the VGA port out of the back and nothing on the system LCD. Have replace both the LCD and the inverter PCBA, but no luck. What else could cause this to happen, even though I am able to load windows xp just fine along with update system to SP3 thinking somehow that it might just help. Still nothing. Unfortunately, my customer wants us to hang on to it until we get it fixed, then notify him. Please help me, if ya can.

Try Fn+F7 first, that is th switch the LCD to VGA. if that doesn't work, you need to go to IBM website download the video management software.

2 ways to solve
1) go to nearby service center which they just replace the motherboard
2) more risky bt work dissamble the whole laptop nd all accries from the motherboard including the cpu ram wifi card nd also black sheet from the main board then place the board in microvave where the vga chip is on the top nd microvave for 6 min at temp of 350 -390 f

Blank Screen


First, confirm that it is the screen itself. Connect the video output to a known working monitor and then power on your Thinkpad. if the known working monitor behaves the same way you can rule out the laptop's monitor as the source of the problem. This may be the BGA, Ball Grid Assembly, leadless soldering problem related to video chips on the motherboard, but first test the monitors.

I have a problem with my ibm thinkpad notebook i want to connect my notebook hp projector how can i


When you connect a data projector or a monitor to the video output connector on the laptop you can toggle the display in various configuration by press and hold the blue Fn key and then press the F7 key (once or a couple of times as required) this key has a blue symbol of a pair of monitors.
Press it once the LCD will switch off and the display will switch to the external video output.
Press it again and the display will be on both the LCD and the external video output.
Press it again and the display will be only on the LCD.

Suspend light


Is your laptops motherboard and vga chipset working? Please try to connect the laptop to another monitor if you are unable to get any image out it might be that the 2nd output is disable OR your motherboard or vga chipset has failed.

If the laptop works on another monitor, then there is still something wrong on the lcd.

But I think there is a more serious problem.

if you need more assitance let me know. good luck.
