Apple devices rely entirely on their logic boards—the central nervous system that coordinates every function from processing power to battery management. When a logic board fails, your iPhone, MacBook, or iPad becomes unusable. At ZA Support in Hyde Park, we've repaired hundreds of logic boards across Rosebank, Sandton, Bryanston, and surrounding Gauteng areas. This guide explains what logic board damage looks like, why professional repair matters, and how our workshop handles these critical components.
What Is a Logic Board and Why Does It Fail?
The logic board is a densely populated circuit board containing the CPU, GPU, RAM, storage, and power management circuitry. Unlike a faulty battery or cracked screen, logic board damage isn't always obvious. You might see a device that won't power on, randomly restarts, charges intermittently, or kernel panics repeatedly.
In our Rosebank workshop, we've identified six common failure modes: liquid damage from spilled water or coffee, failed capacitors from power surges (increasingly common during Johannesburg's load-shedding periods), corrosion from humidity or sweat exposure, loose solder joints from physical drops, thermal damage from prolonged overheating, and manufacturing defects in older models.
Liquid damage is particularly prevalent in Johannesburg suburbs where summer humidity peaks above 60 per cent. Water seeps into board layers, oxidises copper traces, and causes short circuits that cascade across multiple components. We've seen devices recovered from swimming pools that resume normal operation after proper microscopic inspection and component replacement.
A failed power management IC—the chip controlling how electricity flows through the board—can mimic a dead battery. Many users in Midrand and Centurion assume their device needs a new battery when the actual problem sits on the logic board itself.
Our Logic Board Repair Process at ZA Support
Component-level repair, starting from R4499, begins with a thorough diagnostic. Our first step is always a from R599 assessment, conducted on-site in our Hyde Park workshop using specialised testing equipment including oscilloscopes, thermal cameras, and microscopes rated to 200x magnification.
We photograph the board under magnification, document any visible corrosion or burn marks, and test individual power rails using precision multimeters. This diagnostic identifies exactly which chip or component has failed—not just guesswork. For a MacBook logic board, we test the 5V and 3.3V rail simultaneously to pinpoint short circuits within milliseconds.
Once we've identified the failed component, we remove and replace it using micro-soldering equipment. Our technicians hold certification in board-level repair and have trained under Apple Certified Technician standards. We desolder the faulty chip (perhaps a USB-C power controller, audio codec, or storage module), clean the pads with isopropyl alcohol, and solder a new component using lead-free solder rated for Apple's specifications.
The entire process is documented. We retain the original board, photograph each stage, and provide a detailed report. Your device doesn't leave our workshop until it passes a full burn-in test—typically 4 to 6 hours of continuous operation under load.
Why You Need Professional Repair, Not DIY Fixes
Attempting logic board repair at home risks catastrophic damage. Micro-soldering requires reflow stations calibrated to exact temperature profiles; too much heat and you'll delaminate board layers or damage nearby components; too little and the solder joint fails within weeks.
We've received devices from across Johannesburg—Fourways, Morningside, Bryanston—where previous DIY attempts created secondary damage costing far more to repair. A common mistake is applying a general-purpose heat gun to a logic board, melting plastic connectors and nearby capacitors.
Professional repair also preserves your device's integrity. We don't replace the entire board (a practise that voids warranties and wastes resources); we identify and repair the specific failed component, maintaining all original data and hardware signatures.
Logic Board Repair Pricing and Warranty Coverage
Pricing depends on the component and the device model. Component-level repair starts from R4499 for straightforward capacitor or diode replacement. More complex failures—such as replacing a BGA (ball grid array) storage chip on an iPhone—cost R6499 to R8999. A full MacBook logic board replacement, when component-level repair is impossible, reaches R12,000 to R14,000.
Every repair includes a 12-month parts and labour warranty. If the same component fails again within that period, we repair or replace it at no cost. We also offer up to a 3-year extended warranty for customers in Rosebank and surrounding suburbs who want long-term peace of mind.
We operate on a No Fix No Fee basis for diagnostic and assessment work. If we determine your device cannot be economically repaired—or if you decide not to proceed—you pay nothing. This applies across our Gauteng service area including Rosebank, Sandton, and Pretoria.
When Should You Choose Component-Level Repair?
Component-level repair makes sense for newer devices (iPhone 14 onwards, recent MacBook Pro models) where the logic board cost represents the bulk of the device value. A new iPhone 15 Pro logic board costs R8000 to R12,000; we can often repair the same board for 40 to 60 per cent less.
For older devices—iPhone 8 or earlier, MacBook Air 2015—full board replacement is sometimes more economical than component-level repair. We'll explain the cost-benefit clearly during your assessment.
We also recommend component repair if your device contains irreplaceable data or sentimental value. We can often recover a device that competitors declare "unrepairable", simply because we have the equipment and experience to isolate and replace individual failed components.
Related Services: Liquid Damage and Power Issues
Logic board problems frequently stem from liquid damage. Water-damaged devices may not show symptoms immediately; corrosion develops over weeks. If you've spilled liquid on your device, bring it to our Hyde Park workshop immediately—delays increase repair costs.
We also handle logic board repair across all Apple device types: iPhones, iPads, MacBooks, Mac minis, and iMacs. Each device class presents unique challenges (iPhones use compact BGA components; MacBooks use larger through-hole connectors), and our technicians are trained across all platforms.
Service Area: Rosebank, Sandton, Johannesburg and Beyond
We serve Rosebank, Sandton, Bryanston, Fourways, Morningside, Midrand, Centurion, and Pretoria. Customers can drop devices at our Hyde Park workshop, or we can arrange courier collection for suburbs beyond 15 kilometres.
Our workshop operates Monday to Friday, 08:00 to 17:30, with urgent repairs often completed same-day for devices dropped before 10:00 am.

Frequently Asked Questions
Q: How long does logic board repair take?
Diagnostics and assessment take 1 to 2 hours. Component replacement typically takes 24 to 48 hours depending on part availability and complexity. We offer priority turnaround for urgent situations; contact our team for pricing.
Q: Will logic board repair void my Apple warranty?
Logic board repair by authorised technicians (which we are, within component-level scope) doesn't void your existing warranty for unrelated issues. However, if your device is still under AppleCare+, some repairs may be covered through Apple instead—we'll review your specific situation during assessment.
Q: Can you recover data from a device with a failed logic board?
Yes, often. If the storage chip itself is intact (not failed), we can recover data even if the device won't power on. We charge a separate diagnostic fee for data recovery; costs depend on storage size and complexity. For critical data, always back up regularly using iCloud or Apple Cloud.
Q: What's the difference between component-level repair and board replacement?
Component-level repair replaces only the failed chip or capacitor, preserving the original board. Board replacement installs an entirely new logic board. Component repair is cheaper, faster, and better for the environment; we always attempt component repair first unless it's economically impossible.
Q: Is liquid-damaged logic board repair possible?
Yes, if corrosion hasn't compromised multiple components. We clean the board with specialist-grade flux and isopropyl alcohol, inspect under magnification, and replace any corroded capacitors or diodes. Success depends on the damage extent and how quickly you bring the device in.
Q: Do you offer a warranty on logic board repairs?
Every repair includes a 12-month warranty on parts and labour. If the same component fails within 12 months, we repair it free. Optional extended warranty up to 3 years is available at point of repair.
