Signs your MacBook needs board-level repair
If your MacBook does any of the following, the failure usually lives on the logic board itself rather than the screen, the battery or the charger.
MacBook will not turn on
Pressing the power button does nothing — no chime, no fan spin, no keyboard light.
Not charging
MagSafe or USB-C doesn't trigger the charge light, or the system won't run on AC.
Liquid or water damage
Coffee, water, soda or another 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
A faint image visible only with a flashlight, or a black screen while the rest of the system runs.
Fan spins but never boots
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 an overheating component
A specific spot on the board is hot to the touch, fans spin up immediately, or there's 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 under controlled load to see which one has dropped, which is shorted, and where the failure sits.
Short detection
Thermal imaging and current-injection to locate shorted capacitors and other components pulling a rail to ground.
IC replacement (examples, not guarantees)
Many MacBook charging faults trace back to USB-C controllers and charging ICs. The CD3217 and CD3215 are common examples we see, and replacing one can resolve a charging issue — 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.
Corrosion cleanup
Liquid-damaged boards are ultrasonically cleaned and inspected for damaged pads, lifted resistors and corroded traces.
Trace and pad repair
Jumper wires, lifted-pad rebuilds and other component-level fixes that bring a board back without swapping the whole thing.
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 diagnostic finds on your board.
Why component-level repair often beats a full board swap
A full logic board replacement is one of the most expensive MacBook repairs. When a single component is the actual cause, replacing the whole board is rarely the most sensible answer.
What usually makes repair the right call
- A full logic board replacement is often one of the most expensive MacBook repairs there is.
- On some models, replacing the board means 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.
- 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.
Corrosion keeps progressing after the spill, even once 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 — no rice, no hair dryers, no heat
- Contact RevyTech as soon as possible; earlier is better than later
Realistic limitations
- Corrosion keeps progressing even after the device has been dried out.
- Spills involving sugary or salty liquids cause faster, deeper corrosion.
- Long-standing liquid damage can eat through internal copper layers in the board itself, which isn't repairable.
- Boards damaged by repeated power-on attempts after a spill are harder to recover than ones 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 it back far enough to copy data off, then decide whether to proceed with a full repair. Outcomes depend heavily on the failure mode, the state of the storage and prior handling — we don't promise data recovery.
Our MacBook diagnostic process
Every board-level repair follows the same predictable workflow, diagnostic-first, with no soldering work until you've approved the plan.
- Step 1
Intake
We record history — spills, drops, prior repair attempts, recent updates — and the symptoms you've seen.
- Step 2
External inspection
A visual check of the chassis, keyboard and ports for signs of impact, swelling or liquid exposure.
- Step 3
Board inspection under microscope
The logic board comes out and is inspected for corrosion, damaged pads and prior repair signs.
- Step 4
Power & charging rail testing
Each rail is measured under controlled conditions to identify failed components and the actual root cause.
- Step 5
Quote
A clear repair plan, an honest read on whether the board is repairable, and a quote — no work proceeds without approval.
- Step 6
Repair attempt
IC replacement, USB-C controller or connector repair, corrosion cleanup, trace or pad rebuilds, as needed.
- Step 7
Full testing
Boot test, power test, charging test, port-by-port testing and a thermal check before the MacBook leaves the bench.
Pricing, turnaround and warranty
No fix, no fee
Board-level work is no repair, no fee: if we can't fix it, you pay nothing. On mail-in repairs, shipping costs still apply. A simple repair quote by phone or email costs nothing. You always see the quote before we start any repair work.
Turnaround
Board-level work, water damage and severe damage take 1–4 weeks, depending on severity and parts availability. We will tell you where your repair sits in that range once the board has been diagnosed.
Warranty
90-day warranty on every repair — longer on screens and batteries.
Frequently asked questions
Straight answers to the questions we hear most about this repair.
Can a MacBook logic board be repaired?
Often, yes. 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. Severe physical or long-term liquid damage can push a board past the point where repair is safe, and we'll tell you honestly when that's the case.
Is MacBook logic board repair cheaper than replacement?
Usually. A full Apple logic board replacement is one of the most expensive MacBook repairs and, depending on the model, may involve components paired to the original board. A targeted 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 it's brought in quickly. We disassemble, ultrasonically clean affected board sections, inspect under microscope, and repair or replace failed components. Corrosion progresses even after the device has dried out, so the sooner we can clean the board, the better the outcome. Water-damaged devices get a liquid-damage treatment instead of the $55 diagnostic: $100 for phones, $150 for laptops. The treatment adds at least 24 hours to the repair: ultrasonic cleaning, a bath in 99% isopropyl alcohol, then drying overnight.
What if my MacBook can't be repaired?
Board-level work is no repair, no fee: if we can't fix it, you pay nothing. On mail-in repairs, shipping costs still apply. We'll tell you honestly if a repair isn't realistic before you commit to anything.
What if my MacBook will not charge?
This 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, or a shorted component pulling the rail down. We confirm the actual root cause under microscope before quoting any repair.
Can you recover data from a dead MacBook?
Sometimes. When a MacBook won't power on, the storage may still be intact, and the goal becomes bringing the device far enough back to copy data off. We don't promise data recovery success — see our board-level data recovery page for realistic expectations.
Do you repair USB-C charging faults?
Yes. Where the issue is the port itself, the connector can be replaced; where it's the controller or surrounding circuit on the board, that's a microsoldering repair. The diagnostic determines which one applies to your MacBook.
Do you offer mail-in MacBook logic board repair?
Yes, from anywhere in Canada — no-power, not-charging, liquid damage, USB-C faults and other component-level work. See our mail-in microsoldering page for how to package and ship your MacBook.
