Motherboard / Mainboard Replacement: Estimated Labour Charges and Prices in Nairobi
Provider: Pro-Logic Technologies, Kangari Building, Nairobi
The motherboard — also called the mainboard — is the central circuit board of a smartphone. Every other component connects to it: the processor, memory, storage, cameras, charging system, cellular modem, and display drivers. When the motherboard fails, the phone effectively ceases to function regardless of how intact every other component appears. Motherboard issues can range from repairable micro-soldering faults to irreparable board-level damage requiring full board replacement.
Signs of a Motherboard Problem
- Phone does not power on and all other components have been ruled out
- Random reboots, freezes, or bootloops that persist after software troubleshooting
- Multiple functions failing simultaneously (camera, Wi-Fi, and Bluetooth all dead at once)
- No signal or baseband error after confirmed non-software cause
- Liquid damage reaching the board and causing corrosion across multiple circuits
- Phone powers on but does not detect SIM, storage, or screen
Estimated Motherboard Replacement Costs in Nairobi (2024–2025)
Motherboard replacement is the most expensive hardware repair on a smartphone. Prices vary dramatically based on whether an OEM board with matching storage/RAM configuration is available.

Replacing the motherboard on some iPhones resets Face ID permanently, as the Secure Enclave chip is paired to the original board.
Repair First, Replace Second
Many motherboard failures are not actually board-death — they are repairable micro-soldering faults: a lifted pad, a blown capacitor, a corroded connector. Board-level repair at a fraction of replacement cost is often possible. A competent diagnostics technician will always attempt to identify and repair the specific fault before recommending full board replacement.
Pro-Logic Technologies at Kangari Building, Nairobi offers board-level micro-soldering diagnostics before any replacement recommendation is made.
