About this part
The Logic Board Dock Insert (mmWave) (Apple part number LL923-12856) is a genuine Apple part that fits the iPhone 17 Pro (2025). The logic board carries the processor, memory, power management and every connector, so it decides whether the Mac powers on at all.
Signs the logic board needs replacing
- No power, no chime, or a black screen even though the charger light is on
- Random shutdowns, restart loops, or kernel panics that survive a clean macOS install
- Liquid damage, corrosion, or a burnt smell near the board
- Ports, Wi-Fi, or USB-C charging that stop working all at once
Not sure the logic board is the real cause? Our logic board repair service starts with a full diagnosis, and we can install this genuine Apple part for you through our iPhone repair service, in our Tampa shop or by mail-in repair from anywhere in the US.
