T22: white screen

[hansbr]

Hello all,
I would like to have an expert opinion about my problems with the LCD of my T22.
The screen is completely white. That means probably that the inverter and the backlight are fine.
The external VGA port is working correctly on an external monitor.
The Fn-F7 key toggles correctly, the FnHome and Fn End keys work correctly too.
I have the impression that it is a MoBo problem. Do you agree or are there some specific tests that I should do before being sure?
Thanks!!

I would check your LCD cables. It sounds like it is one of the following, and I would check them in this order:

1. Loose LCD cable connection
2. Faulty LCD cable (remember that it can be the tiniest crack)
3. Bad LCD

Thank you very much.
I had already a look at the cable connection without succes. I am afraid it is the connection block on the MoBO that is the cause.
But I will change the LCD cable and then the LCD. I have some spareparts of a T21.
I will let you know the results.

Negative.
I tried another cable and another LCD, but always the same white screen...
Probably the connection socket on the MOBo. If someone has another option or other suggestions I would be very grateful.
For the moment I will use an external screen, no other option..
Thanks
