Hello, Apple tech enthusiasts and loyal iCorrect customers!
As your trusted microelectronics repair specialists in London, we’re committed to providing the highest quality repair services for your Apple products. We believe in transparency and education, which is why we’re sharing a recent discovery we’ve made regarding iPad Pro screen repairs which cause an issue with Pencil after repair.
We made a YouTube short confirming the issue and solution:
In the process of performing screen replacements on the newer generation iPad Pros, we’ve found an unusual issue that significantly affects the functionality of the Apple Pencil. After a screen repair, the Pencil was unable to draw perfect strokes, with the lines becoming jagged instead.
To ensure the validity of our discovery, we conducted extensive tests using an original screen disassembled from another iPad Pro of the same model. This allowed us to confirm that the issue existed in genuine parts.
The Underlying Issue: The Display IC and MAC Address
Our investigation led us to the Display IC, the microchip that controls the screen. We found that this IC is paired to the iPad Pro’s logic board through a unique identifier known as a MAC (Media Access Control) address. When a screen is replaced, the MAC address changes because a new Display IC is introduced. This different MAC address disrupts the proper functioning of the Apple Pencil, as the logic board is still “looking” for the original Display IC’s MAC address.
The Ideal Solution: Apple’s Calibration Software
This issue could be resolved with Apple’s calibration software, which can pair the new Display IC with the logic board, allowing them to communicate effectively. However, this software is not available to the general public or to third-party repairers. This lack of access limits the solutions that we, as repair professionals, can offer to our customers.
Apple’s Current Repair Policies
Furthermore, it’s worth noting that Apple currently does not offer individual repairs for iPads. Instead, if you take your faulty iPad to an Apple Store or an authorised service provider, they generally offer device replacements. This approach is not only expensive for the customer but also contributes to electronic waste.
In the absence of access to Apple’s calibration software, our team at iCorrect has found a solution. By carefully transferring the original Display IC to the new screen during a replacement, we can ensure the Apple Pencil works as intended. This process is delicate and requires the expertise of a microelectronics specialist, which is why we are proud to offer this service as a part of our commitment to quality repairs.
At iCorrect, we believe in the right to repair and will continue to pioneer solutions that benefit our customers and reduce electronic waste. We are committed to staying at the forefront of microelectronics repair, and we’re here to help with all your Apple device repair needs. You can find our iPad repairs here.
