Sony Xperia XZ Premium: Locating display fuse XZ Premium (picture)

Tue, 25 Nov 2025 08:42:32 -0700

Hello all,

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)

The Z5:

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.

Edit:

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.

SONY Xperia XZ3: 再起動が繰り返される。Rebooting repeatedly

Wed, 11 Sep 2024 13:13:31 -0700

再起動が繰り返されて、携帯が使えないです。原因として、simが認識されていないことが考えられるが、simを抜いた状態でも再起動する。インターネットも使うことができない。

My cell phone cannot be used due to repeated restarts. The cause may be that the SIM is not recognized, but it restarts even if the SIM is removed. I can't use the internet either.

Sony Xperia XZ Premium: XZ premium charges after putting pressure

Sun, 30 Nov 2025 12:48:31 -0700

So before my xz premium completely stopped charging my phone used to randomly stop charging and used to charge very slow. I used a quick charge 3.0 charger and certified usb c cable. I had to put the usb type c cable in a certain position to get my phone charging but after a while it completely stopped charging. I inspected the port it was in good shape no bent, nor broken cleaned the port but no luck. So, I started messing with the phone so I find a way to charge it when I put pressure on the bottom of the phone from front and back altogether where usb port and flex cable is connected it starts charging.

UPDATE:The on board connector for the charging port needs to be replaced or resoldered.

Sony Xperia XZ1: [Xperia XZ1 G8342] Phone overheated and doesn't turn on at all

Sun, 15 Jan 2023 09:56:53 -0700

I literally made an account here because I've given up searching. A brief context, I was ordering food on my phone and noticed it was 15% -- No big deal, just charge it right? after charging the phone overheated very quickly, I unplugged (its still alive) and cooled it by just putting a damp cloth on the back side. Once it cooled off, I plugged it in and it dropped from 15% down to 3% then completely blanked.

Went to a repair shop and they deem its a dead battery, but they had no available stock locally. They have to order it from a different state (im not from the US.) which they have mentioned will take 3 weeks and their process was ass. I went around to another shop and this guy mentioned that it isn't battery but possibly my motherboard. I kinda shrug it off and was hoping it was my battery only as its an easy fix. Plus he was the odd suggestion after asking 5 more shops, so I leaned on the battery fix.

Got home and ordered it online myself. I waited 1.5 weeks for the replacement battery, oh my phone worked when I plugged the new battery in BUT --> it overheated yet again, didn't even turned it on. I decided to just let it rest on the table. Came back to it (like barely 10mins?) and its very cool now, no signs of life at all. Man, I just wanna get my files out of here and buy a new one :(

The files is what really matters to me. I'd do anything to fix it as long its not an astounding price tag.

Sony Xperia XZ Premium: How to replace microphone

Wed, 10 Jun 2020 06:29:23 -0700

I have a Sony xz premium. I need to change the microphone, but from pictures it looks like it's attatched to the motherboard. Anyone know how it's attatched and if its easy to change?

Thanks Tom

I have ordered a USB flex but it doesn't look like it has a microphone on it. After doing some research it look like it is on the motherboard (photo below). How would I unsolder this? Would I need a heat gun?

Sony Xperia XZ1 Compact: Backlight stopped working on XZ1 Compact

Thu, 10 Sep 2020 18:25:53 -0700

My beloved XZ1 Compact suddenly, in the middle of the day, had the backlight go out. I can only see the display in bright sunlight. My husband is great at repairing phone issues but this has him stumped. Has anyone done this successfully and can give some advice? I can’t find anyone to repair and it’s out of warranty. There’s no phone out there now quite like this and now, 2 years later, buying another one would cost $200 more than what I spent originally on a new one in 2018!

Sony Xperia XZs: Black screen after display replacement even though the touch works

Tue, 14 Feb 2023 07:46:13 -0700

My screen cracked a few days ago so I bought a new battery and screen. The new battery works fine but the new screen stays black. When touching the screen I get feedback sounds/vibration.

I had the phone running with the broken screen for two days so i still could use whatsapp on my pc, the white backlight still flickered sometimes while it was on.

The old screen is completely destroyed and only came off in 100 pieces.

And the screen stays black regardless of the battery. Everything else works I guess.
