i also found 2 other phones with same problem.
i managed to fix last 2 units by cleaning conectors ,replacing lcd ,and rehoting all mainbord .looks like problem may be with different causes from case to case ...may be driver fault or connector,or pcb ,..
it is a problem with multiple solution ..sow a service manual and some luck may be a good way to start
