Theories about the dead screens

[vegetaleb]

Ok I have 2 lines dead on my P3 screen, though not totally dead...the extreme left side of these are still working!
Now here's my theory:
The second dead line is positioned at the seek and fast forward line, if I touch directly on this line nothing is changed or it will give another operation, now if I put my finger on the left side which still works and keep it on while sliding to the right...the screen works
So the screen in this parts is not really dead,it's perhaps a chip in the motherboard or a screen controller that's bad instead.
Yes I have done 2 hard resets, even used the flash tool posted by Lebelium but the problem is still here, it's definitively a hardware problem but not the screen itself if you ask me
What do you think?
