No backlight after screen replacement z3 xperia compact
I changed the screen because it cracked. When I first tried the screen it was fine and it worked. Then after a while the backlight didn't work. The screen works and I can barely see things on the screen, but backlight is not working.
I read there is a fuse that helps fix this issue but I don't know if this will help. Here it is: http://www.mobilerdx.com/2015/03/sony-xp...
It's the first time the phone is opened and I never thouched the fuse because it's underneath a metallic plate, which I didn't even touch or moved. So why would I have to do something with the fuse if I never did anything to it and the screen was working when I tested it?? It just stopped working afterwards for some unknown reason.
The phone is on, because there is the blinking light. So, do you have some suggestions??? Should I actually try to add a jumper on the fuse??
EDIT: I remember that when I was about to close the phone I put the screen upside down, and it was when the screen backlight stopped working. Is this some reason why the fuse could have been damaged???
