Screen fading white. Is it my LCD? Flex cable? Other?

[SportbikeRiderXX]

My display is progressively showing a mostly white, "washed out" display. It goes from completely normal to the washed out screen you can see in the attached pictures. (two "washed out" screens, followed by two normal) It happens much more frequently in portrait mode. When it first started happening, if I would open the keyboard just a little bit, the "white" would go away and the display would be nice and bright like it should be. At the time, it made me suspect the flex cable, so I disassembled the Hermes and made sure all connections are tight. That did not fix it and it is getting worse. Applying pressure to certain parts of the outside of the device can sometimes cause this to happen, other times it's completely random. Can anyone confirm if it is the LCD or flex cable? I don't mind replacing a part if I can be sure of the problem, but I don't want to waste my time and money if I can't be SURE it will fix the problem.

NO, I can not send it back to AT&T for warranty repair.
