Screen stay black after replacement

Hi everyone!

I have this problem with my Z3 compact, I received a new replacement screen (broke the screen after me falling down and the phone being in my back pocket hit the floor first) and after fitting it, well it doen't light up! Everything else seems to work, the LED lights up when charging, power button works as it vibrates, camera button works as well (the phone vibrates when pressing it) so I think the phone does work.

Also I tried touching the screen, it does make the clicking sound, so the touchscreen is working.

The only problem is that the lcd stays black, no backlight, no images nothing at all! Tried to unplug the battery and plug it back in, still nothing. Volume+ and power did nothing as well.

Any advice or solution on this problem? Maybe the screen is just defective?

Hi,

More than likely a faulty screen.

Try another one and see if that resolves your issue.

If it doesn't, then you may have to inspect the logic board for any damage. :-)
