We've repaired over 18,000 MacBooks across Johannesburg in the last five years, and logic board failures represent roughly 22% of the serious faults we encounter. It's a common problem, it's fixable, and at ZA Support's Hyde Park workshop, we handle these repairs with the precision they demand.
What Is a Logic Board and Why Does It Fail?
The logic board is the motherboard of your Mac β the central processing unit, power management circuits, memory, storage controller, and every other component that makes your computer function. It's also where most of your device's heat is generated.
In our Hyde Park workshop, we've identified three dominant failure patterns. First: thermal stress. When dust accumulates around the heatsink and thermal paste degrades (typically after three to five years), the logic board overheats. Components experience repeated expansion and contraction cycles until solder joints crack invisibly. We call these "cold solder" failures, and they're often intermittent β your Mac works fine for a week, then fails again.
Second: liquid damage. Water, coffee, or even high humidity can corrode the board's pathways and short circuits. Load shedding in Johannesburg means some clients power devices on and off using manual switches or power banks in uncertain conditions, increasing liquid exposure during unstable power states.
Third: manufacturing defects. Certain MacBook Pro models from 2016β2017 suffered from faulty GPU or CPU solder connections from the factory. Apple eventually issued a repair programme, but we still see affected machines arriving at our workshop.
Logic Board Repair in Sandton: Our Process
When you bring your MacBook to us in Sandton or nearby areas, we start with a diagnostic assessment. This costs R599 and includes power testing, kernel panic analysis, and thermal imaging to identify exactly which section of the board is failing.
From there, repair complexity varies. Simple cold solder joints require microsoldering β a specialist technique using a high-powered microscope and micro-scale soldering equipment. We perform this under 40x magnification, literally rebuilding connections smaller than a human hair. This process typically takes 5β7 working days and costs between R1,200 and R2,800 depending on the affected area.
Liquid damage repairs are more involved. We disassemble the device fully, clean affected areas with isopropyl alcohol and soft brushes, replace any visibly corroded components, and then test under load for 24 hours. These repairs take 10β14 working days and cost R1,800 to R4,500. We've documented our liquid damage protocol here: /liquid-damage.
Modular component replacement β for example, swapping a faulty GPU or power management IC β is faster. If a specific chip has failed but the surrounding board is intact, we source a compatible component, remove the failed one using a hot-air rework station, and install the replacement. Turnaround is 3β5 working days, and costs range from R999 to R2,200.
All our logic board repairs include a three-year warranty covering the fault we've repaired, not accidental damage or subsequent failures in unrelated areas.
Cost, Warranty and Comparison to Replacement
Clients often ask: is repair worth it when a replacement MacBook might cost R8,000 to R18,000 from a second-hand supplier?
Our answer is practical. If your MacBook is a 2019 or earlier, and repair costs fall under R3,500, repair is almost always cheaper than replacing a device that still has 4β6 years of useful life remaining. If it's a 2021 or later model with Apple Care, your warranty likely covers logic board faults for R800βR1,500 under accidental damage protection. If it's out of warranty but the machine is recent, replacement cost and hassle often exceed repair.
We've handled this extensively in our main logic board repair guide β you'll find more detail there: /logic-board-repair.
For clients in Sandton specifically, we offer flexibility. Our Hyde Park workshop is reachable from Sandton in under 25 minutes via the M1. We can collect your device, perform repair, and deliver it back, or you can drop it with us directly. If you're uncertain whether repair makes sense for your situation, WhatsApp us on 064 529 5863 β we'll give you an honest assessment before you commit to anything.
Turnaround Times and Load Shedding
Johannesburg's ongoing load shedding affects our workshop minimally β we have backup power systems for diagnostic equipment and soldering stations. However, it does impact parts sourcing. Microcontrollers, power management ICs, and replacement GPUs sometimes take 5β10 additional days to source from international suppliers. We always give you a realistic timeline upfront.
Most simple repairs are completed within 7β10 working days. Complex ones can take up to 14 working days. If your machine is critical for work, let us know β we prioritise urgent jobs and can often squeeze them into a faster slot if you're flexible on the exact date.
Why Choose ZA Support for Logic Board Repair in Sandton?
We've invested in proper diagnostic and repair infrastructure that most computer repair shops in Johannesburg lack. Our Hyde Park workshop has thermal imaging, oscilloscopes for electrical testing, and microsoldering equipment with genuine optics β not the cheap third-party rigs you'll find elsewhere. We've trained our technicians on Apple's proprietary architecture and hold current certification. We don't guess; we test and measure.
We also don't inflate costs to match our competitors. We price based on actual parts and labour, not on what we think customers will pay. You'll usually find our repairs 15β20% cheaper than other certified providers in the northern suburbs.

Frequently Asked Questions
Q: Can a logic board be repaired if water got inside my MacBook?
Yes, in most cases. Water damage doesn't automatically mean the board is beyond repair. If the liquid was clean water or standard beverages, we can disassemble the device, clean the affected components with isopropyl alcohol, replace any corroded parts, and test thoroughly. Salt water or sugary liquids are more complex because they leave residue. We assess every case individually and give you a cost estimate before proceeding.
Q: How long will my MacBook last after logic board repair?
If we've repaired a genuine cold solder failure or replaced a faulty component, the board should function for at least another 3β5 years in normal use. That's why we offer a three-year warranty β we're confident in the repair. That said, if your machine is seven or eight years old, logic board failure is often a sign that other components (battery, trackpad, speakers) may begin to fail soon. Plan for eventual replacement, but a repaired board buys you time.
Q: What's the difference between Apple's repair and ZA Support's repair?
Apple's official logic board service replaces the entire board as an assembly β they don't repair individual components. This is safer but far more expensive, typically ranging from R6,000 to R12,000 depending on the model. We repair the board in place using microsoldering and component-level repair, which is more cost-effective and produces the same functional outcome. Both carry warranty cover. Choose us if budget matters; choose Apple if you want official certification.
Q: Is it safe to use my MacBook while the logic board is being repaired?
No. We require the device to remain powered off throughout repair. Attempting to use a machine with an active logic board fault can cause further damage β for example, a cold solder joint might complete a circuit intermittently, sending voltage where it shouldn't go. Always power down immediately if you suspect a logic board problem.
Q: Do you repair MacBook Airs and MacBook Pros equally well?
Yes. The repair technique is identical. MacBook Air boards are sometimes denser, which makes microsoldering slightly more delicate, but the process and timeline are the same. Cost may vary slightly depending on whether the Air or Pro uses a soldered or replaceable storage module, but repair complexity is comparable.
Q: Can I claim logic board repair on insurance?
Some household or device insurance policies cover accidental damage to MacBooks, including liquid damage and electrical faults. Others don't. We recommend checking your policy wording before you come to us. We can provide itemised invoices and repair reports for insurance claims if needed β contact us with your policy details and we'll advise you on what documentation the insurer will require.
