Dead Pixel on an Older MacBook — Repair or Replace?

Older Retina MacBooks have several display issues that get mistaken for dead pixels, and they have different fixes and costs:

• Dead pixel — a fixed dark dot, sharpest against a white background, same position on every screen. Run the dead pixel test tool full-screen and cycle white → red → green → blue → black. Dead pixels stay black on every colour.
• Stuck pixel — a bright red, green, or blue dot. Unlike a dead pixel, these sometimes recover: run the stuck pixel fix tool for 15–20 minutes before spending anything.
• Staingate / coating delamination— blotchy, smudge-like patches that change with viewing angle, common on 2013–2017 Retina models. This is the anti-reflective coating wearing off, not the panel. Apple's free replacement programme for it ended years ago; polishing off the remaining coating is the common DIY route.
• Flexgate— uneven "stage light" backlight bands along the bottom of 2016–2017 models, caused by a worn display flex cable. This worsens with lid angle; dead pixels don't.
• Dust under the glass— looks like a soft grey speck rather than a crisp dark square, and it's visible even when the display is off under bright light.

Apple's limited warranty is 1 year, and AppleCare+ extends to 3 years — so every 2015–2019 MacBook is now years out of any coverage. Two narrow exceptions worth checking before you pay for anything:

• Consumer-law claims (UK/EU/Australia) — generally up to 6 years in the UK, but in practice claims on a 6+ year-old machine for a single dead pixel are unlikely to succeed.
• Apple service programmes — check apple.com/support/exchange_repair with your serial number. Display-related programmes (staingate, Flexgate-adjacent repairs) have expired, but it costs nothing to check.

For current-generation machines still under warranty, see our MacBook dead pixel guide — Apple's process is much friendlier when coverage applies.

Retina MacBook displays are replaced as a complete lid assembly (panel, glass, backlight, and hinges together), which is why the numbers are high:

• Apple / authorised service— roughly $455–$700 depending on model and size, often near or above the machine's market value
• Independent repair shops — commonly $250–$450 using pulled or aftermarket assemblies
• DIY with a used assembly — $150–$300 from eBay plus a couple of hours of careful work; hinge screws and antenna cables are the usual traps

Compare that against what the machine is worth: a 2015–2017 MacBook Pro typically resells for $200–$450, a 2018–2019 model for $350–$600. An official repair on a 2016 Pro costs more than the entire laptop is worth — which is exactly why most owners of these machines choose to live with a single dead pixel or sell the machine honestly instead.

• One dead pixel, off-centre — live with it. On a 220+ PPI Retina panel a single pixel is ~0.11mm; most people stop noticing within days. Spending $400 to fix it on a $350 laptop is not rational.
• One dead pixel, dead centre — annoying but still rarely worth an official repair. If it genuinely bothers you, price an independent shop or a used lid assembly, and only proceed if the machine otherwise has years of life left (good battery, enough RAM for your work).
• A growing cluster, lines, or spreading dark patches — this is panel or backlight degradation, not a stable defect. It will get worse. Don't spend on repair; plan the replacement of the machine.
• You were already considering an upgrade — a dead pixel is a fine excuse. Apple Silicon machines are a generational jump over any 2015–2019 Intel MacBook, and a defect-free display is part of the deal. Disclose the dead pixel when you sell; it typically knocks $30–$80 off, far less than any repair.

Whichever way you go, run the full test first so you know exactly what you have — count the pixels and note their positions. "One dead pixel, 2cm from the top-left corner" is a very different situation from "several dark spots that weren't there last month."

If the MacBook still performs well and mostly lives on a desk, an external monitor sidesteps the problem entirely — a good 27" 1440p display costs less than any panel repair, and the built-in screen's dead pixel becomes irrelevant for desk work.

Test any external display before relying on it — the monitor test suite at DeadPixelTest.pro covers dead pixels, backlight bleed, and uniformity checks for standalone monitors.
