When liquid damages your MacBook’s logic board, you face a decision that can cost you anywhere from R1,800 to R65,000 depending on which path you choose. Apple will tell you the board needs replacing — they do not offer component-level repair. A general IT shop may offer a board swap from a donor machine, if they can source one. And a specialist like our Hyde Park workshop will offer to repair the specific failed components on your existing board.
Since 2009, we have completed over 25,000 repairs and maintain an 85% success rate on liquid-damaged logic boards. This guide explains exactly what component-level repair involves, when it makes sense, when it does not, and how to make the right decision for your situation.
What "Component-Level Repair" Actually Means
When Apple says your logic board is "damaged" and needs replacement, they are telling you that one or more components on the board have failed. But a MacBook logic board contains thousands of individual components — resistors, capacitors, inductors, ICs (integrated circuits), connectors, and traces. In most liquid damage cases, only a handful of these components are actually affected.
Component-level repair means diagnosing exactly which components have failed and replacing only those — leaving the rest of the board (including your soldered SSD with all your data) intact.
The Tools Required
The Most Commonly Repaired Components
Power Management Unit (PMU) / PMIC: Manages power distribution. Replacement cost: R800–R2,500.
USB-C Controller (ACE3/ACE2): Manages USB-C/Thunderbolt ports. Replacement cost: R600–R1,800.
Charging IC (CD3215/CD3217): Controls the charging circuit. Often the first casualty. Replacement cost: R400–R1,200.
SSD Controller / NAND Storage Controller: Manages solid-state storage. Replacement cost: R800–R2,200. Data can often be recovered.
DRAM Line Components: Tiny passive components supporting memory. Replacement cost per component: R50–R200 (5–15 may be affected).
Display Backlight Driver (LP8550): Controls screen brightness. Replacement cost: R400–R1,500.
Thunderbolt Retimer / Controller: Manages Thunderbolt data protocol. Replacement cost: R600–R2,000.
The Repair Process: Step by Step
Step 1 — Assessment (from R599): Disassembly, battery disconnect, stereo microscope inspection. Detailed, itemised quote provided.
Step 2 — Ultrasonic cleaning: 40kHz ultrasonic cleaner removes corrosion from every surface including underneath BGA chips. 15–30 minutes.
Step 3 — Post-clean inspection: Re-examination under microscope reveals damage hidden under corrosion.
Step 4 — Component replacement: Hot-air rework station removes failed components. Replacements sourced from donor boards or NOS suppliers. IPC-A-610 standards followed.
Step 5 — Trace repair: Fine wire jumpers and solder restore corroded copper traces.
Step 6 — Reballing (if needed): BGA chip removal, pad cleaning, new solder ball application, and resoldering. Cost: R2,000–R4,500.
Step 7 — Functional testing: All systems tested: power, charging, display, USB-C, Wi-Fi, Bluetooth, speakers, camera, keyboard, trackpad, storage. Apple Diagnostics and stress tests.
Step 8 — Quality assurance: Up to 12-month warranty on specific components repaired.
The 85% Success Rate
Our 85% success rate means 85 out of every 100 boards are successfully returned to full working order. The remaining 15% typically involve:
The From R599 assessment guarantee protects you in these cases.

The Insurance Angle
If you have device or business insurance covering accidental damage, our detailed assessment report serves as documentation for claims. Some policies have excess fees that change the calculation.
Load Shedding and Your Decision
If your MacBook was damaged during a load shedding-related power event (surge through USB-C, UPS failure while liquid was present), the damage pattern may differ from a standard spill. Power surge + liquid can affect the Thunderbolt controller and power delivery VRMs specifically. We see 2–3 of these combined cases monthly.
Real Case Studies
Case 1: Bryanston — 2021 MacBook Pro 14-inch M1 Pro, Wine Spill
Brought in within 2 hours. Corrosion on charging IC, three capacitors, and backlight driver.
Repair: R5,200. Apple quote: R24,000. Still running perfectly 11 months later.
Case 2: Sandton — 2020 MacBook Air M1, Water Spill, 5 Days Delay
Would not power on. Extensive corrosion across PMU, USB-C controller, and DRAM passives. Required reballing + 12 component replacements.
Repair: R9,800. If brought in within 6 hours, ultrasonic clean alone (R1,800) would likely have saved it. Apple quote: R18,500.
Case 3: Fourways — 2019 MacBook Pro 16-inch, Rooibos Tea, 3 Months Later
Gradual onset: charging issues, then speaker crackling, then Wi-Fi drops. Corrosion across five circuits. Replaced charging IC, both speakers, Wi-Fi antenna connector, plus extensive trace repair.
Repair: R12,500. Apple quote: R31,000. New 16-inch: R54,000+. Had she come in during Week 1, cost would have been under R3,000.

Frequently Asked Questions
Q: What is the success rate for component-level logic board repair after water damage?
Our success rate is 85% across all liquid damage cases. The remaining 15% involve extensive corrosion, CPU/SoC damage (not replaceable), or multi-layer trace damage. Our From R599 assessment guarantee means you only pay the from R599 assessment if we cannot repair it.
Q: Can Apple repair individual components on a MacBook logic board?
No. Apple’s repair programme replaces the entire logic board assembly, costing R15,000–R54,000. They do not offer component-level diagnosis or repair.
Q: Will I lose my data if the logic board is repaired?
No. Component-level repair preserves your existing logic board, including the soldered SSD with all your data. Apple’s board replacement installs a new board with a blank SSD.
Q: What is reballing and when is it needed?
Reballing removes a BGA chip, cleans the solder pads, applies new solder balls, and resolders the chip. It is needed when corrosion compromises the solder connections underneath a chip. Cost: R2,000–R4,500.
Q: How do you source replacement components?
From three channels: known-good donor boards, new-old-stock (NOS) suppliers, and quality electronic component distributors for common passives. Every component is tested before installation.
Q: Is component-level repair as reliable as a full board replacement?
Yes. Following IPC-A-610 solder joint standards with proper equipment, component-level repair restores full functionality. Our up to 12-month warranty reflects our confidence in the work.
Q: At what point should I just buy a new MacBook?
We use the 40% threshold. If repair cost exceeds 40% of replacement value, consider replacing. Below 30% (e.g., R4,500 on a R42,999 machine = 10.5%), repair is almost always the better option.
Q: Do you provide a written report of the damage found?
Yes. Every from R599 assessment includes a detailed written report documenting LCI status, corrosion location and extent, damaged components, recommended repair plan, and itemised cost breakdown.
