Locating display fuse XZ Premium (picture)
My dad's XZ Premium 'stopped working' like two months ago, he took it to a random repair shop who opened it and poked a lot of components so there's no warranty anymore they thought it was a bad battery for some reason.
I found the phone still worked but the screen appeared to be broken so I thought i'd fix it for fathers day with a replacement screen.
I installed the replacement screen but it still wouldn't work, then I found that if I boot it or make a screenshot even though I don't see anything the screen does in fact show an EXTREMELY low change in brightness. It's barely visible at all.
So I supposed it wasthe backlight that doesn't work, so I've read about backlight fuse/jumper repairs on the motherboard. I check the backlight fuse with a multimeter, and it appears to work fine. Then I want to proceed to check the display fuse, but I can't seem to find it given it is marked with the L like it was on the xperia z5 i've seen in video tutorials.
The XZ Premium motherboard around display connector:
(you can see the V marked backlight fuse just on the left side of the display connector(long white)
Hopefully I can find it and find that the fuse needs fixing otherwise I won't have a clue what the issue is anymore... ;/ If someone has other suggestions, that would also be highly appreciated.
Thanks in advance.
Thanks to Smartfonefix I think I found the issue, visually they already look in bad shape not exactly sure what to test on with these I tried a bit with the diode mode but the numbers don’t say much to me (I do have a working XZ Premium myself to compare values to but I don’t really want to void the warranty on that) though I don’t get a beep on the coil and diode. I’ll try to find out how to confirm it’s either one of these or both but even if it is one I doubt it’s a diy fix. (i think it’s the correct ones that are in the top left/middle-left.
Es esta una buena pregunta?
