When your Mac or iPhone stops working, the logic board—or motherboard—is often the culprit. We've been repairing logic boards in our Hyde Park workshop for over a decade, and we've learned that early intervention saves thousands of rand. This guide covers what logic board damage looks like, why Melrose residents choose our repair service, and what to expect when you bring your device to us.
What Is a Logic Board and Why Does It Fail?
The logic board is the main circuit board inside your Mac, iPhone, or iPad. It controls every function: processor speed, memory management, power distribution, and communication between components. Think of it as the brain of your device.
Logic boards fail for three main reasons:
Liquid damage is the most common cause we see in our Melrose clinic. Coffee, water, sweat, or humidity corrodes the copper traces and component solder joints. Even "waterproof" iPhones fail when liquid reaches the logic board.
Thermal stress happens when your device overheats repeatedly—blocked vents, heavy rendering workloads, or failed cooling fans force the solder joints to expand and contract until they crack. We've seen MacBook Pro logic boards fail after years of video editing without proper thermal paste replacement.
Component failure occurs when individual chips (the power management IC, GPU, or memory modules) wear out electrically. This is rarer but often requires micro-soldering expertise.
Our from R599 assessment will pinpoint the exact failure. Most repairs in Melrose are completed within 3–5 working days.
Board-Level Repair vs. Apple's Swap Model
Apple's standard approach is replacement: your logic board is defective, so they swap the entire unit. In Johannesburg, this costs R8,000–R15,000 and takes 5–10 working days if parts are in stock.
We repair at the component level. Our technicians use microscopes, hot air rework stations, and micro-soldering equipment to remove the failed chip, clean the board, and install a replacement component. This approach costs 40–60% less than Apple's swap and often finishes faster.
When to choose component repair:
When Apple swap makes sense:
We've repaired hundreds of Melrose and Hyde Park devices that Apple's diagnostic flagged as "logic board failure, replacement required." Ninety-three percent of those repairs succeeded at component level and cost our customers half what Apple quoted.
Common Logic Board Issues in Melrose
No power or intermittent shutdown. The power management IC has failed, preventing the board from distributing voltage to the CPU. We remove the damaged chip, replace it with a known-good unit, and calibrate the battery sensor. Cost: R1,200–R2,800 depending on your device model.
Screen black, no response to key presses. Often the GPU (graphics processor) is damaged. We've seen this in MacBook Air units left in hot cars or exposed to humidity during Johannesburg's rainy season. Replacement: R2,200–R4,500.
WiFi and Bluetooth not detected. The WiFi/Bluetooth module has corrosion or a loose solder joint. We clean and re-flow the module or replace it entirely. Cost: R800–R1,800.
Battery won't charge past 80%. The charging IC or power delivery circuit is failing. We replace the specific component, then calibrate the battery firmware. Cost: R1,100–R2,400.
Kernel panics or unexpected restarts. RAM or the memory controller is faulty. We test with diagnostic software, identify the failing chip, and replace it. Cost: R1,500–R3,200.
All repairs include up to a 3-year warranty on parts and labour. If the same component fails within that window, we repair it free.
Our Melrose Logic Board Repair Process
Step 1: Assessment (from R599). You'll drop off your device or book an appointment online at zasupport.com/book. Our technician will power it on, run diagnostics, and use thermal imaging to check for liquid damage. We'll text you a detailed report within 2 hours.
Step 2: Quote and approval. We send you a quote via WhatsApp (064 529 5863) or email. No Fix No Fee means if we can't repair it, you pay nothing. You approve by replying "yes" or call us to discuss options.
Step 3: Component-level repair. Our micro-soldering specialist removes the logic board, isolates the failed component under the microscope, applies flux and solder paste, and uses a hot air rework station to remove the old chip. A replacement component is cleaned, tested on a reference board, and installed. The board is then washed in isopropyl alcohol, dried, and reinstalled.
Step 4: Calibration and testing. We power on your device, run Apple Diagnostics (or Macs) or iPhone Diagnostics, test battery charge and discharge cycles, and verify all sensors and ports. Your device must pass full diagnostics before leaving our workshop.
Step 5: Warranty certificate. We provide a printed warranty document. Your repair is covered for up to 3 years—parts and labour—against the same fault. (Normal wear, accidental damage, and liquid exposure are excluded unless you've paid for our premium protection plan.)
Why Melrose and Surrounding Areas Choose ZA Support
We're based in Hyde Park, five minutes' drive from Melrose. Residents in Melrose, Sandton, Bryanston, and Rosebank can reach us easily without heading to the CBD. Our technicians are Apple Certified (where available) and have handled logic boards from every generation: Intel and Apple Silicon Macs, iPhone 6 through iPhone 15, iPad Pro units with M1 and M2 chips.
We've also built a reputation for honesty. If your device has damage we can't repair affordably, we'll tell you upfront—no hidden fees, no upsell. Many customers return because they trust us.
We're POPIA compliant. Your device data stays secure. If you're concerned about privacy during repair, we can replace the SSD or erase the logic board's firmware before work begins.
Prevention: Protecting Your Logic Board
Avoid liquid exposure. Melrose's humid summers and unexpected rain make liquid damage common. Use a screen protector, keep your device away from water, and invest in a protective case.
Manage heat. If you use your MacBook for video editing or 3D rendering, ensure the vents are clear. Replace the thermal paste every 18–24 months (R450–R800 service). Elevate your MacBook on a stand to improve airflow.
Use a surge protector. Johannesburg's load shedding and power fluctuations can damage the power management IC. A quality UPS or surge-protected power strip costs R300–R800 and prevents thousands in repair bills.
Back up regularly. Even if we can recover your data during logic board repair, a Time Machine or cloud backup is faster and safer.

Frequently Asked Questions
Q: How long does a logic board repair take?
Most component-level repairs are completed within 3–5 working days. If we need to order a replacement chip from our supplier, it may take up to 7 days. You'll get a timeline at your assessment appointment.
Q: Will a logic board repair erase my data?
No. We repair the board, not the storage. Your files, apps, and settings remain intact. If your device powers on after repair, everything will be there.
Q: Can you repair a logic board damaged by liquid?
Yes, provided the damage is limited to corrosion on a few components. If the liquid has spread across multiple sections or damaged the RAM and CPU simultaneously, we'll let you know at assessment. Most liquid damage repairs cost R1,800–R4,200 and take 5–7 days.
Q: What's the difference between "micro-soldering" and "hot air rework"?
Hot air rework uses a heated air gun to melt solder and remove or replace small components without cutting traces. Micro-soldering is more precise—we use a soldering iron under magnification for repairs that require millimetre-level accuracy. Most logic board repairs use hot air rework; only complex multi-layer repairs need micro-soldering.
Q: Is the warranty valid if I drop my device later?
Our warranty covers the repaired component, not accidental damage. If you drop your device and the logic board fails again, that's a new fault outside warranty. However, if the same component we repaired fails from normal use within 3 years, we'll fix it free.
Q: Can I send my device by courier instead of visiting Melrose?
Yes. Post your device to us with a description of the fault. Include your contact number. We'll assess it, send you a quote via WhatsApp, and begin work upon your approval. Courier is slower but safe if you're outside Melrose.
