Signs your MacBook needs board-level repair
If your MacBook is doing any of these, the failure usually lives on the logic board itself rather than on the screen, the battery, or the charger.
MacBook will not turn on
Pressing the power button does nothing — no chime, no fan spin, no light at the keyboard.
No power
No signs of life even when plugged in to a known-good charger and a known-good cable.
Not charging
MagSafe / USB-C doesn't trigger the charge LED, or the system won't run on AC.
Liquid or water damage
Coffee, water, soda, or other liquid spilled into the keyboard or onto the board.
USB-C charging issues
Charges only on certain ports, only with certain cables, or stops charging intermittently.
No image or backlight
Faint image visible only with a flashlight, or a completely black screen with the rest of the system running.
Fan spin but no boot
The MacBook starts up — fan spins, lights come on — but never reaches macOS or the Apple logo.
Random shutdowns
Kernel panics, sudden power-offs, or restarts that started after damage or with no obvious cause.
Shorted board or overheating component
A specific spot on the board is hot to the touch, fans spin up immediately, or a measurable short on a power rail.
Data needed from a dead MacBook
Photos, projects, and files trapped on a MacBook that no longer powers on.
What MacBook logic board repair actually looks like
Component-level diagnostics on a MacBook means measuring power rails, finding shorts, and replacing the parts that have actually failed — instead of swapping the whole board.
Power rail testing
We measure each power rail with the MacBook under controlled load to see which one has dropped, which one is shorted, and where the failure is upstream.
Short detection
Thermal imaging and current-injection techniques help locate shorted capacitors and other components pulling a rail to ground.
IC replacement (examples, not guarantees)
Many MacBook charging-related faults trace back to USB-C controllers and charging ICs. The CD3217 and CD3215 are common examples we see, and CD3217 replacement or CD3215 repair can resolve charging issues — but the actual repair depends entirely on what the diagnostic finds on your board.
Connector repair
USB-C / Thunderbolt port replacement, board-to-board connector repair, and display flex connector replacement when the connector itself is damaged.
Corrosion cleanup
Liquid-damaged boards are ultrasonically cleaned and inspected for damaged pads, lifted resistors, and corroded traces. Affected components are replaced.
Board repair where appropriate
Trace repair, jumper wires, lifted-pad rebuilds, and other component-level fixes that bring a logic board back without swapping the whole board.
Note: technical part references (for example, CD3217 / CD3215 USB-C controllers and shorted capacitors on a power rail) are common examples we see, not guarantees that they apply to your specific MacBook. The actual repair always depends on what the microscope-based diagnostic finds on your board.
Why component-level repair often beats full board replacement
A full logic board replacement is one of the most expensive MacBook repairs there is. When a single component is the actual cause, replacing the whole board is rarely the most sensible answer.
- A full Apple logic board replacement is often one of the most expensive MacBook repairs
- On some models, replacing the board can mean replacing components paired to the original board
- Component-level repair targets the actual failed part — usually a fraction of the cost of a board swap
- You keep your original board, your storage, and the data on it
- Caveat: not every MacBook board is repairable; some failures and some prior damage push a board past the point where repair is worthwhile
Spilled something on your MacBook? Time matters.
MacBook liquid damage repair (water damage, coffee, soda, beer, salt water, anything sticky) is one of the most time-sensitive jobs on the bench. Corrosion keeps progressing after the spill — even after the MacBook has been dried out.
Do this right now
- Power the MacBook off — hold the power button until it shuts down
- Do not charge or plug in the MacBook after the spill
- Disconnect any USB-C / Thunderbolt accessories
- Stand the MacBook in a tent shape to drain residual liquid; do not use rice or a heat source
- Contact RevyTech as soon as possible — earlier is better than later
Realistic limitations
- Liquid damage worsens over time — corrosion keeps progressing even after the device has been dried out
- Severe spills involving sugary or salty liquids cause faster, deeper corrosion
- Long-standing liquid damage can eat through internal copper layers in the PCB itself, which is not repairable
- Boards damaged by repeated power-on attempts after a spill are harder to recover than ones that were powered down quickly
Repair-first cases when the data matters most
Some MacBook failures are repair-first data recovery cases
When a MacBook won't power on but you mainly need the files inside, the goal of the repair shifts: bring the MacBook back far enough to copy data off, then decide whether to proceed with a full repair afterwards. Outcomes depend heavily on the failure mode, the state of the storage, and prior handling. We do not promise data recovery — we share realistic expectations before any work begins.

Our MacBook diagnostic process
Every MacBook board-level repair follows the same predictable workflow — diagnostic-first, with no soldering work until you've approved the plan.
Intake
We capture history: spills, drops, prior repair attempts, recent macOS updates, and the symptoms you've seen.
External inspection
Visual check of the chassis, keyboard, ports, and any signs of impact, swelling, or liquid exposure.
Board inspection under microscope
The logic board comes out and is inspected under stereo microscope for corrosion, damaged pads, and prior repair signs.
Power & charging rail testing
Each rail is measured under controlled conditions to identify failed components, shorted rails, and the actual root cause.
Quote
You receive a clear repair plan, an honest read on whether the board is repairable, and a quote — no work proceeds without approval.
Repair attempt
Microsoldering work: IC replacement, USB-C controller / connector repair, corrosion cleanup, trace or pad rebuilds, and other board repair as needed.
Full testing
Boot test, power test, charging test, port-by-port testing, and a thermal check before the MacBook leaves the bench.

Frequently asked questions
Quick answers to questions we hear from customers about this service.
Can a MacBook logic board be repaired?
Often, yes. A great many MacBook board failures come down to a single failed IC, a corroded section after a liquid spill, a damaged USB-C / Thunderbolt port, a blown fuse, or a shorted component on a power rail. Component-level board repair targets the actual failed part instead of replacing the whole board. Severe physical or long-term liquid damage can push a board past the point where repair is safe — we will tell you honestly when that is the case.
Is logic board repair cheaper than replacement?
Usually, yes. A full Apple logic board replacement is one of the most expensive MacBook repairs and, depending on the model, may involve replacing components paired to the original board. A targeted MacBook logic board repair fixes only the failed component and lets you keep the original board and the data on it. We diagnose first and quote both options when relevant.
Can you repair a liquid-damaged MacBook?
Often, yes — especially if the MacBook is brought in quickly. We disassemble, ultrasonically clean affected board sections, inspect under microscope, and repair or replace failed components. Liquid damage is time-sensitive: corrosion progresses even after the device has been dried out, so the sooner we can clean the board, the better the outcome. Severe or long-term liquid damage may not be repairable.
What if my MacBook will not charge?
MacBook not-charging repair is a common board-level case. The fault could be a damaged USB-C / Thunderbolt port, a failed USB-C controller, a charging IC, a blown fuse on the charge rail, or a shorted component pulling the rail down. We confirm the actual root cause under microscope before quoting any repair work.
Can you recover data from a dead MacBook?
Sometimes. When a MacBook will not power on, the storage may still be intact and the goal becomes getting the device far enough back to copy data off — or, where required, working at the chip level. We do not promise data recovery success. See our board-level data recovery page for realistic expectations on this kind of work.
Do you repair USB-C charging faults?
Yes. USB-C / Thunderbolt port damage, USB-C charging issues, and USB-C controller faults are common reasons a MacBook stops charging. Where the issue is the port itself, the connector can be replaced; where it is the controller or surrounding circuit on the logic board, that is a microsoldering repair. The diagnostic determines which one.
Do you offer mail-in MacBook logic board repair?
Yes. We accept mail-in MacBook logic board repair from across Canada — no-power, not-charging, liquid damage, USB-C faults, and other component-level work. Power the MacBook off, pack it securely, insure the outbound shipment for replacement value, and contact us first so we can confirm next steps. See our mail-in microsoldering page for full guidance.
