hello there,
It s not PA Problem, just connection between PCB and BGA Comp. is bad, because too often pressed while using your keypad.

your T28s problem can be solve like this :
Try to use hot air, and put some flux on BGA IC near FLASH IC ( 2 IC BGA) . Dont use to hot, just medium temperature, and also small air pressure.

Guaranteed 100 %.....
