I would like to attempt a repair but wanted to make sure that this problem is identifiable and won't turn into a fishing expedition before I make the time and repair investment.

Thanks,

M.

I recently replaced the battery in my iPhone 14 Pro. After the replacement, the phone started overheating right after turning it on. To rule out the new battery as the cause, I reinstalled the original battery, but the issue remains the same.

I checked all connectors and flex cables – everything seems properly connected, and there is no visible physical damage inside. However, I noticed that the main processor itself gets extremely hot immediately after powering on.

Has anyone experienced something similar or knows what could cause this? Could it be an issue with the power management IC or a short somewhere around the CPU?

this is my first post here because I have two iPhone 14 Pro‘s with an bug that seems so weird to me. I repaired both phones displays and now I encountered the weird situation that the proximity sensor seems to not work right and is super unreliable.

Both phones have DD Aftermarker Soft Oleds with 120 Hz Rate + transplanted Display IC. The phones work fine but the only thing that happens is that if there is a new message the display won‘t get activated to show the popup and that during listening to an Whatsapp voicemail e.g. the proximity function activates random and if activated sometimes doesen‘t end itself unless you push the powerbutton.

I did further testing with different flexes, I put new adhesive on the sensor because I thought it was bleeding light and nothing helped. If I disconnect the flex at all, I get a lit up display on pop up messages, proximity logically doesen‘t work anymore.

I also did an full reset using DFU, nothing changed.

One more thing I noticed is that when I put pressure on the display while in phone in an certain area around the corners, the proximity gets activated and if I take my finger away it sometimes deactivates and sometimes not.

The only thing I can imagine to be the cause is the display itself because its the same error in 2 phones. But the seller said they had no problems with it in general. What I also don‘t understand is why I get lit up screen without flex and no lit up at all when connected even tho the prox is not activated all the time until I put pressure or it‘s randomly activated.

Last step will be to buy another display for me but maybe someone has encountered the same problem or has an hint for me.

Thank you very much,

Yours

Theo

I want to replace the cable, so could someone please make a how-to video?

Please help as I am a beginner at repairs!

My device is iPhone 14 Pro.

I'm thinking of buying an used iPhone 14 Pro for 300€, but the Owner says it got a small Problem. The Screen randomly goes black for a few Seconds and Turns Back on, while the Phone IT self ist working very good.

Now my question: is it possible to repair the thing so it works normaly? (And thr Owner got the battery and backcover replaced a while ago)

Now, after reassembly, the iPhone is boot looping every ~3 minutes, and Apple diagnostics say that the "Compass Sensor Test" fails. Also, the compass does not, in fact, work. I have reseated all visible flex cables; no fix.

Anyone know if this is repairable, or where the compass is located or connects? Can't find anything similar online.

Here is the first section of the panic log:

Then I waited for the iOS18.0.1 and after that I cant make calls or use 4G/5G. After the 18.1 still the same.

No sim working on my device but all 3 i tried working on other devices

I tried restart, on/off airplane mode, reset network connections. I did format the phone clean and with backup but still no calls.

After the format 5G is working slowly but it stops when i try to make a call or someone is calling.
