Chosen Solution
After few months of using my Xperia XZ (F8331) fell and broke it’s screen… So i bought new one and replace it, but it doesnt have backlight… Everything its working but so dim i need flashlifht to see anything on screen. P.S. I’ve read few posts on similar problem and i think it is a backlight fuse…. but i cant find it….
here is the solution: https://www.youtube.com/watch?v=3K1kw3Gh… allthough this video shows soldering a jumper you should solder a new coil as there is danger of burning more parts in this circuit which the coil is meant to be protecting. Polish guy likes to do it the rough way it seems :-)
