MacBook Display Issues (2016-2020): Flexgate & Screen Problems
Introduction
Does your MacBook Pro display suddenly have stripes, flicker or show an uneven "stage light effect" at the bottom edge of the screen? Then you may be affected by the notorious Flexgate problem. We explain what causes it, which models are affected, and what repair options exist.
What is the Flexgate Problem?
Flexgate is a design flaw that mainly affects MacBook Pro models from 2016 to 2020. The problem arises from display cables that are too short or too delicate, which wear out from repeatedly opening and closing the laptop.
The Most Common Symptoms:
- Uneven lighting at the bottom edge of the display (the "stage light effect")
- Colored or gray vertical lines on the screen
- Screen flickering, especially when moving the display
- Complete display failure, the screen stays black
Which MacBook Models Are Affected?
| Model | Years | Risk Level | Most Common Issues |
|---|---|---|---|
| MacBook Pro 13" | 2016-2020 | 🔴 Very High | Flexgate, stage light, complete failure |
| MacBook Pro 15" | 2016-2019 | 🔴 Very High | Vertical stripes, flickering |
| MacBook Pro 16" | 2019 | 🟢 Low | Rare, Apple lengthened the cables |
| MacBook Air | 2018-2020 | 🟢 Low | Occasional cable issues |
| MacBook 12" | 2015-2017 | 🟡 Medium | Display connection vulnerable |
Especially Critical: Touch Bar Models
MacBook Pro models with Touch Bar (2016-2020) are particularly vulnerable as the display flex cable runs directly alongside the Touch Bar cable. Mechanical stress often affects both components simultaneously.
Apple slightly extended the cable design from 2018 (from 2mm to 6mm), which reduced the problem but didn't completely solve it.
Recognizing Symptoms: Does Your MacBook Have a Display Problem?
Early Warning Signs (Stage 1):
- Occasional brief flickering when opening
- Slight brightness differences at bottom edge
- Display takes a moment to "wake up"
Clear Symptoms (Stage 2):
- Bright spots at the bottom display edge (stage light effect)
- Colorful or gray vertical lines
- Regular display flickering
- Pink or green color distortions
Critical Symptoms (Stage 3):
- Image only visible at certain angles
- Areas of the screen remain black
- Complete failure, no image at all
- White screen where only the backlight is visible
Quick Test for Flexgate:
- Turn on MacBook
- Slowly open display from 45° to 120°
- Wait 5 seconds at each angle
- Watch for flickering, stripes or dropouts
Result: If problems only occur at certain angles → Flexgate likely!
Technical Causes in Detail
1. Cables Too Short
The display cables in affected models are minimally sized. They are stretched and bent with each opening and closing.
2. Material Fatigue
The thin flex cables consist of delicate conductor tracks that can break through repeated movement.
3. Heat Development
The position of the cables near heat-generating components accelerates wear.

Short-term Measures:
- Try adjusting the display angle, find one where the problem is minimal

Prevention Tips:
- Always open the display from the center, slowly

Frequently Asked Questions about MacBook Pro Display Problems
What is the MacBook Pro Flexgate problem?
Flexgate is a design flaw that mainly affects MacBook Pro models from 2016 to 2020. The display cables are too short or too delicate and wear out from repeatedly opening and closing the laptop. This first leads to uneven backlighting (the "stage light effect") and later often to complete display failure or vertical stripes.
Which MacBook Pro models are affected by display problems and Flexgate?
The MacBook Pro 13" and 15" models built between 2016 and 2020 are particularly prone to display-cable issues like Flexgate. Apple slightly adjusted the design in later years, but similar symptoms can occur on other models too.
What does a Flexgate repair cost?
Costs vary significantly. Repairing the cable itself is very labor-intensive and rarely offered. In most cases, the full display assembly has to be replaced. At Sadaghian we offer a cost-effective, sustainable alternative: replacement with tested, used original displays. Contact us for a free diagnosis and a non-binding quote.
Does Apple have a Flexgate repair program?
Apple ran a free repair program for certain 13" MacBook Pro 2016 models with backlight issues, but the program was limited and doesn't cover all affected models or symptoms. We recommend checking with Apple first to see whether your device is still eligible.
Can I repair the display problem myself?
DIY repair is not recommended. The display cable is extremely delicate and replacement requires specialist tools and experience. A failed attempt can cause additional damage. Professional repair is the safer option.
How long does a display repair take?
Usually 1–2 business days for a display-assembly replacement. High volume or parts-ordering can extend this slightly. We inform you of the expected duration right after diagnosis.
Will I lose my data during a display repair?
No. A display repair doesn't touch your data. The display is a separate component, so the SSD and everything stored on it remain untouched.
How do I know if my MacBook is affected by Flexgate?
Typical signs: stage-light effect along the bottom of the screen, display only works at certain opening angles, vertical stripes, or flickering. If you notice any of these, a professional diagnosis is advisable.
Other Display Problems (Not Flexgate)
Not every display problem is Flexgate. Here are other common causes:
LCD Panel Defects:
- Dead pixels, individual dots stay black or white
- Pressure marks, dark spots from mechanical pressure
- Display crack, spider web pattern after a drop
- Liquid crystal failure, black spots spreading across the screen
Graphics Chip Problems:
- Horizontal stripes, often pointing to a GPU problem
- Artifacts like geometric patterns or colorful blocks
- Kernel panic, system crashes under graphics load
Software Problems:
- Problems appearing after a macOS update (driver incompatibility)
- If an external monitor works fine, it's usually a software issue
- If Safe Mode works, there's likely a software conflict
Diagnosis Tip: Connect an external monitor. If it works perfectly, the problem is likely with the display or cable, not the graphics chip.
