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??

Thanks.

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???

Thanks

Hi, I had the same problem and took the risk of making the jumper. I used a conducting glue instead of soldering the thing because it is so tiny, I do not own the tools for it.

It worked fine using this glue, my screen is as bright as it should be!

I got someone to fix it for me. I didn't do it because you need the tools and I didn't have them. But where the picture shows is where you need to solder. The guy that did it soldered a very thin metal cable in that spot. So yes, it should work. It's how I got mine fixed. But you definitely need tools for soldering such a small part. It's not easy. I tried it and couldn't do it. So I had someone do it for me.

Hi there. I've replaced the screen of my z3 compact. I think have connected the lcd screen properly, in fact it turns on, but the touch screen is not working. Can you help me to get why and fix it?

Hi all,

got a similar problem. The backlight of my Sony Xperia Z isn't working after I replaced the backcover only, I haven't touched anything but the backcover and two screws that fell out, as I opened the phone's back. Anyone think it's still the fuse or got any other idea?
