Try to repair water damages of your flex. You need microscope and steady
hands. You will see broken links. Try to restore them. B.R.

i have same problem, but my one's flex is good, because i tried with another working 8800, anything works fine, but all ic on borad are sealed, so i think that is display ic problem
