backlight doesn't work in close position
I have a R800i (Xperia play)
THe backlight is working in the open position.
But not in the closed position.
The display is working then, since i can unlock the phone by pushing the power button and swipe the screen.
The unlock sound is played.
Only the screen stays dark !
In the service test the slide open and slide close are sensed OK.
any suggestions .....
