iPhone 12: Can I clean the Ambient Light Sensor with ispropryl?

Thu, 01 Sep 2022 20:43:44 -0700

Coworker brought in his wife’s iPhone 12 that was having issues with the screen being super dim randomly after it boots. Figure it’s probably the ambient light sensor and sure enough find the tiniest spot of patina on one of the contact points on the back of the display where a drop of water got in (trying to explain to people that’s enough to kill something is a struggle though)

I’m not interested in fussing around with transferring components over to a new flex to keep Face ID (because reasons) so he’s just getting a Self Repair display and I’m going to do it for him since his wife wants to make sure Face ID stays intact.

In the mean time. The ALS works sometimes, if it feels like it. I’m figuring there’s some corrosion or something somewhere I can’t see because my microscope is at home. How risky is it to try and clean the ALS up with some isopropyl. Is that going to murder it more?

iPhone 12: Screen stops working after replacement

Fri, 19 May 2023 13:16:05 -0700

After replacing the screen on the iphone 12 it will work fine and then just stops responding, sometimes right away sometimes days later. Open up unhook and rehook the same screen and it works again. Have tried other screens and it acts the same. Is this a software issue? Or is the iPhone 12 the vista of the iPhones?

iPhone 12: TBK 958A Not displaying iPhone 12 and up back glass laser schematics.

Mon, 08 Nov 2021 08:43:41 -0700

So we have a TBK 958a back glass laser machine and when the iPhone 12 came out we downloaded the schematics from the official website, loaded them onto a USB, put them in the TBK 958A and the file shows when we transfer the files to the machine via USB but when we click on the image it comes up blank. And I got my files directly from the website here http://www.shenwangda.com/en/h-col-125.h...

Has anyone here successfully updated their TBK-958A to fit the iPhone 12 and up models? We tried different formats on the USBs and that didn’t work. If anyone here has had some success please feel free to help a fellow tech out. :)

iPhone 12: Can I transfer pictures with a broken screen?

I dropped my phone in water and the screen stopped working and responding. It still responds with Vibrations when turned into silent mode and I turned the flash light on by accident too. I was wondering if there is any way I can recover my pictures to my new phone that were not yet backed up on my iCloud Photos.

iPhone 12: Phone keeps going in to recovery mode

Thu, 23 May 2024 12:23:13 -0700

Hello,

I am having trouble getting my iPhone 12 to boot up. The screen is damaged with vertical lines and when turned on it goes straight to recovery mode. I have plugged in to iTunes and it successfully completes the restore, however once it is finishes with the cycle it still boots in to recovery mode instead of ios. I have connected to 3utools and tried the exit recovery mode option but it just boots back to it,

Also, the phone won't turn on when pressing the side button, only when the charging cable is plugged in (stays on with cable unplugged after so no issues with battery). I am able to use the side button and volume buttons to reboot so I don't think any of those are stuck and forcing it in to recovery mode.

I have opened up the phone and tried disconnecting the earpiece speaker and front sensor assembly but it doesn't make a difference. Any ideas what could be causing it and what else I could try?

Thanks in advance

iPhone 12: Battery connector damaged while replacing screen - view for more detai

Sat, 05 Aug 2023 10:13:56 -0700

So I did a full test of 256gb iphone 12 which included face id working perfectly and screen brightness being fine, however upon damaging the battery connector the faceID does not work, the screen brightness is also lowered and the battery shows as non genuine (even though it is) and has no percentage at the top right when it used to. I just want to know if it is the battery that caused no faceid?

All these images contain an image of the front earpiece and connector, front sensor connector on the iphone 12 and also battery + battery connector. Only the battery seems to be damaged
