At ZA Support, we've spent the last eight years repairing logic boards across MacBooks, iPhones, iPads, and Apple Watches in Hyde Park, Sandton, Rosebank, and Morningside. We've learned that logic board damage rarely announces itself clearly. You might see random restarts. Your machine might charge erratically. The display could flicker or stay black. By the time you recognise the problem, the damage is usually weeks old—and waiting longer only compounds the cost.
This post walks you through what logic board failure looks like, why it happens, how we repair it, and what to expect in terms of cost and turnaround time.
What Is a Logic Board and Why Does It Fail?
The logic board—officially called the main logic board or motherboard in Apple devices—is the central nervous system of your computer, tablet, or phone. Every function your device performs travels through this board: processing data, managing power delivery, controlling display output, handling wireless connections, and storing information. For a MacBook Air, the logic board might be roughly the size of a credit card but contains billions of transistors. For an iPhone 14 Pro, it's smaller still.
Logic board failure occurs through several mechanisms. BGA (Ball Grid Array) components—tiny processors and chips soldered to the board using microscopic solder balls—can separate from the board due to thermal cycling. Every time your device heats up and cools down, the solder expands and contracts. After hundreds or thousands of cycles, those tiny connections fracture. A MacBook left in a hot car, then used in a cold office, experiences dramatic thermal stress. A device used continuously during Johannesburg's summer months and then stored in an air-conditioned room overnight is undergoing repeated expansion and contraction.
Liquid damage is the second most common cause. Water, coffee, or soft drink exposure—even a small splash—can corrode solder joints, bridge circuits, and activate corrosion that spreads over weeks. We've seen devices fail completely three weeks after a seemingly minor spill because the corrosion process continued invisibly beneath the surface. If your device has experienced any liquid contact, professional inspection is essential. Our workshop uses ultrasonic cleaning and microscopic inspection to identify corrosion before it becomes catastrophic.
Power delivery problems create a third category of failure. Modern Apple devices use sophisticated power management systems. A faulty voltage regulator or charging circuit can damage the entire logic board within hours. We've diagnosed MacBook Pros that died after a third-party charger delivered incorrect voltage.
Logic Board Repair: Methods and When We Use Them
We employ three primary repair methods at our Hyde Park location, and diagnosis determines which is appropriate for your device.
Trace repair and micro-soldering form the first approach. A logic board contains hundreds of copper traces—microscopic pathways connecting components. Corrosion from liquid damage or physical damage can sever these traces. Using a binocular microscope and micro-soldering equipment, we can re-establish those connections by carefully applying new solder to restore the circuit. This requires steady hands, proper training, and equipment costing more than R120,000. It's not a service every repair shop can offer. We perform trace repair for iPhones, iPad Pros, and MacBooks where the damage is localised and the device's overall logic board structure remains sound.
BGA reflow is our second method. When a processor or graphics chip has separated from the board due to thermal cycling, we carefully reflow the solder—heating it until it melts and re-establishes connection. The process is delicate. Temperature must be precise; too hot and you damage surrounding components, too cool and the connection never forms. We use controlled reflow stations with exact temperature profiles for each Apple device model. A MacBook Air logic board requires different temperatures than an iPhone 12 logic board. We've invested in equipment and training specific to Apple's designs.
Component-level replacement is our third method. Where a specific chip has failed irreparably, we can remove the faulty component and install a replacement. This is common for charging circuits, power management ICs, and certain processors. For older models like the MacBook Pro 2012–2015, we stock common failing components. For newer devices, component sourcing becomes complex and expensive because Apple uses proprietary chips.
Morningside Location and Service Area
We're based in Hyde Park but serve Morningside directly. The Morningside Medical Precinct is roughly 8 kilometres from our workshop—a 12-minute drive depending on traffic. Many Morningside professionals bring devices to us rather than posting them because of the speed and the ability to discuss repairs face-to-face. We've repaired logic boards for doctors, dentists, and office staff throughout Morningside's business district.
Our service area includes Sandton, Rosebank, Bryanston, Fourways, Centurion, Midrand, and Pretoria. If you're in Morningside and prefer not to visit in person, we accept devices via courier. We've partnered with same-day courier services to manage turnover quickly.
Cost and Warranty
Logic board repair costs depend on the type of failure and your device model. We offer a comprehensive assessment from R599—this includes diagnosis, visual inspection under microscope, power-on testing, and a written report detailing the specific failure and repair cost. Many customers are surprised how affordable certain repairs are once diagnosis is complete. Others learn that repair costs exceed replacement value, and we help you explore that decision frankly.
Most repairs range from R1,800 to R6,500, depending on whether we're performing trace repair, BGA reflow, or component replacement. A MacBook Pro logic board repair typically costs more than an iPhone repair because the board is more complex. A device with multiple areas of damage might exceed R7,000.
We offer up to a three-year warranty on logic board repairs, depending on the repair type and device model. If the same fault recurs within the warranty period, we repair it at no cost. This warranty gives you confidence that the repair is genuine and durable, not a temporary patch.
We also offer No Fix No Fee. If we diagnose a fault and determine that repair isn't economically sensible—say, the logic board is too damaged and replacement would be more cost-effective—we don't charge you for diagnosis. You walk away with clear information and no bill.
Why Professional Repair Matters
Logic board repair is not a DIY activity, and it's not a service every phone repair shop can provide. A shop without proper microscopy, thermal equipment, and experience will either turn you away or offer a temporary fix that fails within weeks. We've repaired devices that other shops declared "unrepairable" because they lacked the tools or training.
At our Hyde Park workshop, we've invested in professional-grade equipment: digital microscopes, temperature-controlled reflow stations, vacuum desoldering tools, and component-level diagnostics. Our technicians have completed manufacturer training and accumulated thousands of hours of practical experience. This infrastructure exists to give you certainty: if a logic board can be repaired, we can repair it.
Getting Started: Assessment and Booking
If you're in Morningside or anywhere across Gauteng and suspect logic board failure—your device won't power on, charges erratically, restarts randomly, or shows no response—contact us for assessment.
WhatsApp us on 064 529 5863 for quick enquiries, or book your assessment at zasupport.com/book. Assessments take 24–48 hours once received, and we'll contact you with findings and a fixed repair quote.

Frequently Asked Questions
Q: How do I know if my device has a logic board problem rather than just a dead battery?
A logic board failure typically presents with specific symptoms: the device won't power on even after extended charging, you see no lights or response to button presses, or the device powers on intermittently and then dies. A battery issue usually allows the device to at least respond (show the low-battery screen, vibrate when plugged in, or show a charge indication). Our R599 assessment includes power diagnostics that distinguish between these faults within minutes.
Q: Can I repair a logic board myself?
Logic board repair requires specialised equipment: microscopes (minimum 20× magnification), temperature-controlled reflow stations (±2°C precision), micro-soldering tools, and desoldering equipment. Equipment alone costs R80,000–R200,000. More importantly, logic boards are tiny and extremely fragile. One slip with a soldering iron can destroy a R15,000 component. We recommend professional service because the risk of total device loss is high and the tools required are beyond reasonable DIY investment.
Q: How long does logic board repair take?
Assessment takes 24–48 hours. Once you approve repair, most jobs complete within 5–7 working days. Complex repairs involving multiple damage sites or rare components can extend to 10–14 days. Urgent turnaround (48-hour repair) is available for an additional R800 surcharge. We'll confirm realistic timescales during your booking.
Q: Will a logic board repair void my AppleCare+ coverage?
AppleCare+ generally covers manufacturing faults but not physical damage or liquid damage unless you've purchased accidental damage protection. Independent repair (including ours) does not void your AppleCare+ coverage under South African Consumer Protection Act guidelines. However, if you later need Apple service, you may be asked about prior repairs. We recommend checking your specific AppleCare+ terms, but our repairs do not cancel your coverage.
Q: What is the difference between BGA reflow and trace repair?
BGA reflow restores connection between a processor chip and the board when thermal cycling has separated the microscopic solder balls holding it in place. We apply precise heat to melt the solder and restore the connection. Trace repair addresses broken copper pathways on the board itself (often from corrosion or physical damage). We identify the broken trace under microscope and apply new solder to bridge the gap. Both are micro-level repairs requiring specialist equipment, but they address different failure modes.
Q: Do you offer warranty on logic board repairs?
Yes. We offer up to a three-year warranty depending on repair type and device model. If the same fault recurs within warranty, we repair it at no cost. Warranty covers the specific repair performed—for example, if we reflowed a BGA component and it fails again, warranty applies. It does not cover new faults (like a second damaged component) or damage from future liquid exposure.
