Z3 Compact no display - GSM-Forum

Plasmacoil · 04-15-2015, 15:49

Hi all,

Changed the screen with a genuine Z3 compact replacement. The display does not light up but the device responds to touch. Does anyone know what causes this? I have tried another Genuine screen and it has the same problem.

Is this a back light issue? any help would be welcome.

Same problem with me.
I changed the screens (LCD and touchscreen) on two Sony Z3 compact but since both phones have no image.
I can hear the phone start and I see the back-light will turn on but I have no picture.

PS: I tried a flash with Flashtool but it did not solve my problem.
PS2: I also tried to replace it with another LCD but still more image.
PS3: I search near the CPU a fuse, but nothing
