Common Logic Board Faults We Fix
Every fault below is covered by our standard assessment process. We use professional specialist equipment for all microsoldering work.
No Power
MacBook shows no signs of life, no fans, no display, no LED. Board-level power circuit diagnosis and repair.
No Display
Mac boots but screen stays black. GPU failure, backlight circuit, T-Con board, or display cable fault.
Liquid Damage
Corrosion on traces and component pads after liquid exposure. Professional board cleaning and component replacement.
Overheating / Shutdown
Thermal runaway, failing voltage regulators, or blocked power rails causing unexpected shutdown.
USB-C / Thunderbolt Failure
No charging, no external display, or no data on USB-C ports. Controller chip or port board replacement.
Fan Error / Loud Fan
SMC fault, fan controller issue, or failed thermal sensor causing fan to run at maximum speed.
GPU Failure
Screen artifacts, garbled display, or external display failure. Discrete GPU restoration or replacement.
Kernel Panic / Crash
Persistent kernel panics traced to failing RAM, storage, or logic board component fault.
Why Component-Level Repair Beats Full Board Replacement
Most MacBook logic board failures are caused by a single failed component, not the entire board. Replacing the whole board when only one chip has failed is unnecessary, expensive, and causes you to lose your original hardware pairing.
Your data stays on the device
Component-level repair leaves your storage, your files, and your operating system completely untouched. Board replacement on M-series Macs means losing everything on the soldered SSD.
Touch ID pairing preserved
The Touch ID sensor is paired to the T2 chip or Secure Enclave on your original board. Replacing the board breaks this pairing permanently. Microsoldering keeps your original board intact.
Faster turnaround
We fix the component that failed, not the whole board. Most repairs are completed in 24–72 hours. Board replacement often requires a week or more while parts are ordered.
IC Fault Reference, Chips We Replace
Our technicians work at component level. Below are the most common integrated circuits (ICs) we replace on MacBook and Mac logic boards, with the models affected, typical symptoms, and repair approach.
| Chip / Component | Affected Models | Typical Symptom | Our Repair | Risk |
|---|---|---|---|---|
| AMD GPU (MXM) | MBP 2011–2013 | Screen artifacts, no video, garbled display | GPU restoration or replacement | High |
| CD3217B12 | MBP/MBA 2016–2019 | No charging, USB-C dead on one or both sides | Controller chip replacement | Medium |
| TPS51980 | MBP 2013–2016 | No power, fan spin then shutdown, 0V on PPBUS_G3H | Power management IC replacement | High |
| LP8550 | MBP/MBA 2012–2017 | No backlight, dim or flickering display | Backlight driver IC replacement | Medium |
| Thunderbolt Controller | MBP 2011–2014 | No Thunderbolt, kernel panic on attach, port dead | Thunderbolt IC replacement | Medium |
| T2 / SMC / Apple Silicon | MBP 2018+, MBA 2020+ | Loop boot, DFU required, USB-C only powers with specific cable | T2/SMC-adjacent component service, DFU restore | High |
Risk rating indicates complexity of the repair, not likelihood of success. Assessment fee: R899 ex VAT, absorbed into repair cost if you proceed. 3-month warranty on all repairs.
Microsoldering vs Board Replacement
✓ Microsoldering Repair (Our Preference)
- Fixes the specific failed component only
- Your original board, your data stays put
- 60–80% cheaper than board replacement
- Preserves pairing with Touch ID / Secure Enclave
- Backed by ZA Support warranty
- Completed in 48–72 hours in most cases
Board Replacement (When Necessary)
- –Required only when repair is not feasible
- –Higher cost, full board + installation
- –Loss of pairing on Touch ID-dependent features
- –Data migration required (if SSD changes)
- –Still includes ZA Support warranty
- –Used for: severe burn damage, multiple failed chips

What Our Customers Say
“My 2019 MacBook Pro was completely dead after a coffee spill. Brought it to ZA Support in Hyde Park and they had it diagnosed within a few hours. Turned out to be corrosion on the USB-C controller. Fixed for a fraction of the cost of a new logic board. Cannot recommend highly enough.”

“Screen was showing strange lines and flickering on my MacBook Pro 2015. I had been told it was unfixable or quoted a high price for a replacement board. ZA Support diagnosed it as the GPU and repaired it at a fair price. 3-month warranty included. Six weeks on and it is perfect.”

“MacBook Air M2 would not charge on either USB-C port. ZA Support found a failed charging controller chip and replaced it same day. They were upfront about pricing, no surprises. Clear written quote before any work began. Will definitely use again.”
