My girlfriends 6230 has been doing some odd things lately.

The display has gotten very faded, if you increase the viewing angle (ie. tilt the phone all the way up) you can see the display flashing on and off. Display is not viewable from standard viewing angle.

Now, she used to be able to solve the problem by dropping it. Which lead me to believe that there was a loose connection or dry joint. Although recently this very technical "repair" (dropping it) has not been able to fix it.

So I opened it up, and checked all connections and they seem fine. I also tried flicking all the circuit boards, and the problem would not go away.

Does anyone have any ideas? Is the display borked? A bad connection? Firmware upgrade?

Any ideas are appreciated, because I don't get any until its fixed
