yo Venemo,
as far as i know, when i install (and i had/have) the extra kernel to overclock they wont repair it even if i had a warranty.
and it has nothing to do with the hardware, becazse if this had to do something with hardwar like flexcable isnt connected righ the backlight wont go on, but my problem is like the other way arround
the bcklight is the biggest problem, the other problems arnt that important.
