About this part
The Logic Board Bus Bar (Apple part number 923-07149) is a genuine Apple part that fits the Apple Studio Display (27-inch, 2022). 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 Mac repair service, in our Tampa shop or by mail-in repair from anywhere in the US.
