Hi everyone,
I’m looking for a schematic, boardview, or partial Ethernet circuit diagram for my Mac Mini M2 Pro (2023).
Model: A2816
Logic board: 820-02832-05
Related board number: 820-02832-A
The Mac was damaged during a lightning strike while unplugged from power but connected to Ethernet. The surge appears to have travelled through the Ethernet cable, as my router’s connected port was also fried.
Since then, the Mac shows a blinking red status light and no display output.
Initial diagnostic advice suggested a firmware issue. The Mac is still detected in DFU mode and correctly identified as an M2 Pro, but every firmware restore fails partway through. The process involves a roughly 20–30 GB download, but installation never completes.
I’ve tried original Apple cables and several other Macs, including friends’ MacBooks and another Mac Mini. Multiple repair shops have also tried without success.
A technician suspects a short circuit near the Ethernet/network section, but the shops need a schematic or boardview to investigate further. I’ve wondered whether damaged SSD/storage circuitry could explain the failed restores, but this hasn’t been confirmed.
There’s no Apple Store or Genius Bar in my country, and finding an identical working board for comparison is very difficult.
If anyone can help with any of these, I’d really appreciate it:
A schematic or boardview for this board.
Ethernet controller details, component locations, or a partial circuit diagram.
Experience repairing this model after Ethernet surge damage.
A recommendation for someone who can repair it.
This is my main work machine, and I can’t afford to replace it right now. Any files, technical guidance, or repair leads would mean a lot.
Thank you for reading and for any help!
