The display service on iPhones has become even more complicated

For the 13 Series, the Face ID tiny authentication chip is in the feed-through cable between the motherboard and the panel, coded.


In the case of used iPhones that have undergone more serious servicing, Face ID has often stopped working, but in the case of the 13 series, the situation has become even more complicated, as the display of the mobiles is individually coded to the motherboard, the rice grain-sized processor and an authentication chip is soldered to the ribbon cable between the two components.

Of course, the solution is available to authorized Apple service centers and service partners contracted with the manufacturer who have direct access to the factory part, with which the units can be programmed, but at first there will certainly be few smaller services where this can be remedied.

Smaller repair companies will have the option of soldering the old chip off the cable and relocating it again, but this is not a risk-free operation and due to the many tiny connectors, it has to work very precisely, making operation almost impossible with a manual soldering iron. A very similar thing happened last year with the iPhone 12-series camera, in which we wrote an article involving an important player in the domestic repair industry, but in the meantime Apple backed out of the complete restriction of the unencrypted camera module, and after an iOS update, these cameras worked, only an error message was thrown at startup.
