Black Screen, No Boot, LCD is on but nobody's home.
I've recently replaced the screen on my Z3 Compact (I've done this a few times before...) but I think this time I've definitely done something wrong.
Symptoms are as follows:
Phone is on, LCD is working (I can only tell this from the backlight being on) but nothing will boot up. I turn the phone on and I don't get a splash screen or boot up noise.
I've tried resetting it using the power button/volume switch but still get nothing
