hi to all

im a new user in this forum
well i have an I Phone with problem on LCD

the problem is this:
the camera, photos, calendar and text functions does not work.
is very strange because when i want to shut down the phone, the slide button works fine

do you know what is the problem?

i opened the phone and wll is ok.
i restored the firmware and nothing.

the firmware was 1.1.1 and i upgraded to 1.1.4

any idea??
