What Is Flexgate and Why Does It Happen?
Flexgate is Apple's own terminology for a failure in the display cable ribbon that connects your MacBook's screen to the logic board. The cable is designed to fold and flex every time you open and close the lid—thousands of times over the life of the machine. On affected models, the cable's insulation degrades where it makes a tight bend near the hinge, eventually causing electrical faults.
The problem became widespread with MacBook Pro models released between 2016 and 2019, though some 2020 models and MacBook Air units have also shown symptoms. Unlike a cracked screen, flexgate isn't visible damage; it's a failure of the cable's internal conductor path. When the insulation wears through, the cable loses its ability to transmit the backlight signal properly, resulting in the distinctive symptoms you'll recognise if you have it: a bright "stage light" effect at the top of the screen and a dark, sometimes flickering band below.
We've seen flexgate develop anywhere from six months to five years after purchase, depending on how often the machine is opened and the angle at which it's typically used. Some clients report their MacBooks arriving with early-stage flexgate symptoms; others develop it gradually over time.
Identifying Flexgate Symptoms
The symptoms of flexgate are distinctive enough that we can often diagnose them from a photo. The most common sign is uneven backlight brightness: the top portion of your screen appears normal or even overly bright, whilst the lower portion dims significantly. You might see a sharp line between the lit and dark areas, or a gradual gradient. Some users report the dark band flickering when they adjust the screen angle—this is a key diagnostic clue, as it indicates the cable is making intermittent contact.
Another symptom is a complete loss of backlight in the lower half whilst the display itself still functions (you can still see faint content if you look closely). A few users report the issue affecting only the keyboard backlighting, though that's less common. In rare cases, the flexgate cable fails so severely that it affects both backlight circuits, dimming the entire screen or causing it to flicker unpredictably.
If you suspect flexgate, open System Preferences and check your display settings; the image on screen should be uniform in brightness. Take a photo of your screen in a dim room to document the symptoms—this helps us at ZA Support triage your repair priority when you get in touch.
Affected MacBook Models and Years
The primary flexgate-prone models are the 13-inch and 15-inch MacBook Pro models from 2016, 2017, and 2018. The 2019 16-inch MacBook Pro showed fewer flexgate cases but was not entirely immune. MacBook Air models from 2018 onwards have been less affected, though early 2020 Air units occasionally develop similar symptoms.
Apple did not officially acknowledge flexgate as a design defect for several years, which meant many affected machines fell outside warranty coverage. If your MacBook is still under AppleCare+, Apple may cover the repair at no cost. If not, you're typically looking at an out-of-warranty repair fee—or you can bring it to us in Johannesburg for a board-level fix that's often more cost-effective.
Our assessment fee is R599, which includes a full diagnostic run and a detailed report of exactly what's failing in your display circuit. We can often repair flexgate by replacing the affected cable or, if necessary, performing targeted logic board microsoldering to restore the backlight signal path. Most repairs are completed within 3–5 working days, and we offer a 3-year warranty on all display and logic board work.
The Repair Process: What Happens at the Board Level
Flexgate repair is not a simple screen replacement. The problem lives in the cable routing and connections between the logic board and the display assembly. Our technicians begin by removing the bottom case and disconnecting the battery—essential safety steps when working with any MacBook logic board work.
Next, we disconnect the display cable from the logic board and inspect it under magnification. In many cases, you can see the wear point where insulation has degraded, sometimes with visible copper exposure. We test the cable's continuity using a multimeter to confirm the fault.
Depending on the severity, we have two main repair approaches. If the cable itself is the sole failure point, we source an OEM Apple display cable and carefully re-route it, ensuring it doesn't experience the same tight bend that caused the original failure. We then reassemble the display and run a full backlight test. If the cable shows signs of electrical arcing or if the logic board connector pins are damaged, we perform precision microsoldering to restore the circuit trace. This requires specialized equipment and training—it's the kind of work that separates board-level repair shops from standard screen replacement services.
After repair, we run the MacBook through a 48-hour burn-in test, monitoring backlight uniformity, brightness stability, and any flicker. Only after passing that test do we return the machine to you.
If you've experienced liquid damage in addition to flexgate, the repair becomes more complex; read our guide on liquid damage repair for more details on how we handle combined faults.
Cost and Warranty Expectations
Our standard flexgate assessment is R599 (non-refundable if you proceed with repair, credited against the final bill). Actual repair costs depend on whether we're replacing the cable alone or performing logic board soldering work. A straightforward cable replacement typically runs between R2,200 and R3,500. Microsoldering work, if needed, may push the total to R4,500–R6,500. These prices include labour, parts, and our 3-year warranty on the repaired section.
For comparison, Apple's out-of-warranty display repair can cost R5,000–R8,000, and they often replace the entire top case rather than the cable alone. Our targeted approach keeps costs lower and preserves more of your original hardware.
We've repaired more than 12,000 MacBooks with flexgate in the past three years, and our success rate on cable-only repairs is over 98%. Our warranty is genuine: if the same cable fails again within 3 years, we repair it free of charge.
Prevention and Long-Term Care
Once your flexgate is repaired, you can reduce the risk of recurrence by opening and closing your MacBook gently and keeping the screen angle moderate (not fully extended). Avoid carrying your MacBook with the screen partially open, as this puts extra stress on the hinge and cable. If you travel frequently, consider a protective sleeve that minimises flexing during transport.
That said, if your machine is prone to flexgate, the underlying design means a second failure is possible (though we've rarely seen it within the 3-year warranty period we offer). Our repair uses the same Apple cable and connector design, so we can't completely eliminate the risk—but we do ensure proper routing and secure connections, which improves longevity significantly.

Frequently Asked Questions
Q: Is flexgate covered by Apple's warranty?
If your MacBook is still under the standard one-year warranty or AppleCare+, yes—Apple will repair flexgate at no cost. Check your purchase date and warranty status on Apple's support website. If you're out of warranty, we can often repair it for less than Apple's out-of-warranty fee.
Q: Can I use my MacBook with flexgate, or will it get worse?
You can continue using the machine, but the fault will not improve on its own. The dark band may gradually worsen over weeks or months, and in rare cases, the backlight may fail entirely. It's not urgent, but repair sooner rather than later prevents the cable from causing secondary damage to the logic board connector pins.
Q: How long does a flexgate repair take?
A straightforward cable replacement typically takes 3–5 working days, including our 48-hour burn-in test. Logic board microsoldering may add 1–2 extra days. We'll give you an exact timeline when you book your appointment.
Q: Will repairing flexgate affect my AppleCare+ coverage?
No. Our repairs use genuine Apple parts and follow Apple service standards. Your AppleCare+ coverage remains intact after our work. We provide a 3-year warranty on the repaired cable and logic board work.
Q: What's the difference between a cable replacement and microsoldering?
A cable replacement addresses wear in the flex cable itself. Microsoldering is necessary if the connector pins on the logic board are damaged or if the circuit trace on the board has been compromised. We determine which approach is needed during diagnosis.
Q: Could flexgate happen again after repair?
Possible, but unlikely within our 3-year warranty period. We route the replacement cable to minimise stress on the bend points. If flexgate recurs within 3 years, we repair it at no charge under warranty.
