I recently dropped my phone and smashed the Digitiser. It's 3 years old, it's the original Desire G7 A8181. After dropping it all was well, other than the smashed digitiser. I decided to replace the digitiser as the phone was fine other than this. I received the digitiser and followed a guide to installing the new one, All seemed fine, as far as I was aware I was very careful to take it appart properly and put it together, I even inspected parts as I went to be sure I didn't break anything. I put the phone back together with the new digitiser in place and turned the phone on for the AMOLED screen to not respond whatsoever. Doesn't even light up. I looked closely and could see a line swooping across the AMOLED screen and assumed it was a crack. I assumed that at some point when installing the new screen I had bent and cracked the screen SO I ordered a new screen. It arived today, I put it together, installed it as correctly as I could and voila, nothing. Screen is still black, no response however the digitiser works and so do all the buttons because I can answer calls by swiping down when it rings.. Any ideas? Or anyone know where to start diagnosing the problem? I'm dieing without this phone at the moment..... Cheers!
