Stage-light effect along the bottom of the display, or backlight cutting out at full open? Flexgate cable replacement.
Flexgate is a known design fault on the 2016–2018 MacBook Pro. Apple routed the display flex cable across the lower edge of the screen, where it bends sharply every time the lid opens. Over thousands of cycles the cable wears through and the backlight signal starts dropping out — first as a vertical 'stage-light' gradient along the bottom of the display, then as full backlight cut-off when the lid is opened past 90°.
The fix is the cable itself. A new flex cable from Apple's revised batch (post-2018, with extra length built in) restores the display fully. The repair requires opening the display assembly, which is glued — done carefully, the display goes back together cleanly.
Apple's repair pathway is to replace the entire display assembly at high cost. The fault is the cable; we replace just the cable.
We use the post-2018 longer cable. The original-length part has the same wear vector and will fail the same way.
Flexgate affects 13" and 15" MacBook Pros 2016–2018. If your model is later, the display fault is something else and we'll tell you what to look at instead.
Free photo quote — pricing depends on model (13" vs 15") and on whether the display panel itself has any collateral damage.
For comparison, Apple’s repair pathway is to swap the entire display assembly — a several-hundred-pound part. Cable-only repair is significantly cheaper either way.

Two stages. First, a vertical 'stage-light' gradient along the bottom edge of the screen — bright bands or shadows in line with the LED zones. Second, the backlight cuts out completely when the lid is opened past about 90°, returning when you partly close it. If both symptoms match, it's almost certainly flexgate.
Apple's standard repair is a full display assembly swap, which on a 2016–2018 Pro is a several-hundred-pound part. The actual failure is a flex cable inside the assembly that costs a fraction of that — but the assembly isn't designed to be opened, so most service centres won't attempt it.

13" and 15" MacBook Pros from 2016 through 2018. The 2018 13" Pro received a slightly longer cable mid-production but still fails. From 2019 onwards Apple revised the cable routing and flexgate as such doesn't affect newer models — different display faults exist on those, but they're not this.
We fit the longer revised-length cable, which substantially reduces the bend stress at the failure point. Within reasonable use, the fix should outlast the rest of the laptop. 90-day warranty applies on the work either way.
No. The repair is contained to the display assembly. The SSD, logic board and battery are not touched. Files and settings are unaffected.
Typically 5–10 working days because the display adhesive needs cure time during reassembly. We confirm timeline with the quote.

Hark Tech is a UK mail-in repair service for MacBook Pro display problems, including the flexgate backlight cable fault common on 2016–2018 models. You post your laptop in, receive a written quote, and nothing proceeds until you have approved it.
The cost varies by model and how far the cable has degraded. Because flexgate involves the backlight flex cable rather than the full display assembly, it is typically one of the more contained MacBook Pro display repairs. Send a photo showing the stage-light band at the bottom of the screen, or describe when the backlight cuts out, and you will receive a firm price via the free quote form before you post anything.
It depends on the model year and extent of the cable wear. Flexgate is a cable replacement rather than a full display swap, so it tends to be less costly than a complete screen repair. Use the free photo quote form to get a written price with no obligation before sending your laptop in.
The stage-light glow along the bottom of the display is the classic flexgate symptom on 2016–2018 MacBook Pros. Send a photo and the model details via the free quote form and you will receive a firm price. Nothing is charged until you approve it.
Yes. Hark Tech is a UK mail-in repair service — you post your MacBook from anywhere in the UK, receive a written quote, and it is returned once the repair is done. No in-person appointment needed.
The fault is most common on 2016, 2017, and 2018 MacBook Pro models. The backlight flex cable runs through the hinge and wears with repeated opening and closing. Symptoms typically worsen over time — earlier repair usually keeps the cost lower.
Often yes. If the rest of the machine is working well, restoring the backlight extends the laptop's life at a fraction of replacement cost. A free photo quote will give you a firm repair price so you can make an informed decision before committing to anything.
