Screen died!

Hello!

Reecntly changed lcd on my xperia m4 aqua!

Worked fine for 2 mintes. When i was unlocking patters screen went black, thought maybe locked itself up. tried to unlock it! I could feel the vibrations and sounds that i am typing my code but the screen is black. Thought maybe display died. Opened it up again. Put on old display and the same problem. Phone works but display not showing. Tried reinstalling android. Didnt work.

What could be the problem and what could be the cause?

Check if the ribbons are properly connected, also, how did the prior screen stopped working? water damaged? dropped? etc perhaps the motherboard it's damaged

i dropped the phone from 30cm height and it cracked, working fine but glass shattered! after about 30mins i accidently sqeesed it or smthg and lcd cracked and had loose connection. I ordered a screen on ebay and asked my electricion friend to switch it. He ran into this problem. i dont have glue anymore and he tried putting old screen on and it did the same. Touchscreen working but display not!

It might be something other than the LCD, maybe something like this
