Since some days, my n900 mixes all lines from display when I type.

For example, the time is in the middle of the screen, but just half mixed with other lines.

Tried to replace the display (the whole sliding part) with no success. Seems to be on the motherboard. Bad contact somewhere.

Life span? shock?

I have few hope but if someone faced to that once, I'd like to know the trick.

(Got another n900 on ebay for parts these days, opened it, the touchscreen flat cable was just out of the plug )
My Pro1(order) will have to wait !
