Something happened to me when I was repairing the iPhone X I damaged a piece of the main camera’s FPC connector and in the upper left corner of the main circuit board a piece of the plating is gone (copper shows through). The device works perfectly except for one error that I couldn’t find anything about on the Internet: A kernel panic with thermalmonitored error and missing sensor TP1A I couldn’t find anything about the TP1A. It will probably be near the camera connection? After unplugging all components, the error still occurs and the device restarts every 3 minutes. But there was a short time when loading, the device didn’t restart for 1 hour? In a Chinese forum, the battery is listed as the error description for the TP1A, without further information on it. Is that correct? The built-in battery is already too “old” (1000 cycles with 82% capacity) anyway, but it still worked without any problems. Does it have to be flushed out? I’d rather have it than something to do with the logic board ;) Could someone enlighten me more about the TP1A?
So if it’s not any of the usuals, it could also be that there is a board level issue preventing the flash sensor from communicating. there are some components related to that data in that area, I don’t remember what the identifier for that sensor is in the logs. A little digging makes me think that TP1A might also be related to one of the thermistors that are on the board. I have never fussed with them to know if they cause those same sort of 3 minute panic issues, but it’s would make sense. One of them is located at the top right of the “wide” camera connector, which is the top one of the two. I think that’s the one, you are referencing? They may be covered over by some silicone or other sort of protection. I don’t have iPhone X board hand to check. Anything around connectors usually is, but if you peel away that coating I wonder if both the resistor and the capacitor here are intact. There are a couple other places those show up on the board, but this one makes the most sense.
Uploading some pictures of the damage you’re looking at could certainly help point us in the correct direction as well. Which pin on the camera connector is the one that’s the issue? What was the initial problem you were fixing?
This error is caused by a faulty charge port. It has nothing to do with the camera. You will need to replace the charge port. Make sure you purchase one from a reputable store.
