Display won't turn on after replacement
I replace a display from a Xperia tablet Z and I tested it before installation. When I tested it everything is OK. I applied double face tape around the frame and I install the new display. I try to turn it on but the display won't show image.
PC recognize the tablet when I connected, I made a firmware upgrade, but the display won't work. I check all connections to logic board and everything looks good.
Please help me
Is this a good question?
