Flexgate issue? Here is how to fix it

The MacBook Flexgate problem is a design flaw that affects several MacBook Pro models from 2016 to 2017. The issue is with the cable connecting the display to the logic board. Over time, the flex cable can become damaged, resulting in a dim or flickering display. If you’ve been having display problems with your MacBook Pro, it could be due to the Flexgate problem.

Not sure what the Flexgate issue is or how to resolve it? Don’t be concerned; I’ve got you covered. This article will cover everything you need to know about the Flexgate problem, including how to identify it and what you can do to resolve it. Let’s get this party started.

Flexgate is a display backlight issue in certain MacBook Pro models. This problem is known as Flexgate because it occurs in the flex cable that connects the display to the controller logic board.

This problem occurs when the flex cable on the MacBook is damaged. The issue is caused by the cable’s fragility and the way it is routed through the MacBook’s hinge mechanism, which puts strain on the cable over time. It occurs because of the Mac lid being opened and closed repeatedly.

Causes of Flexgate problem

The Root Cause of the Flexgate Problem

The MacBook Pro was completely redesigned in 2016.

Until 2015, Apple housed the MacBook logic board or display controller beneath the display in the hinge cover. The wire connecting the logic board to the display never had to bend or stretch because it was part of the lid.

However, Apple redesigned the MacBook Pro in 2016, separating the logic board and display controller. The board is now housed within the main chassis, beneath the touch bar. The flex cable connecting the display to the board is now a spring-ed ribbon cable wrapped around the hinge. This makes it even more prone to breaking over time as a result of the constant tension and relaxation when opening and closing the lid, unlike the previous design, where the wire connecting was tucked inside the hinge cover and never moved.

Symptoms of the Flexgate Issue

1.     Stage Light Effect

When the flex cable does not completely break, but some connection lines in the cable are damaged, the stage light effect in MacBook Pro occurs. The flex cable is made to wrap around the hinge, pulling taut when the lid opens and relaxing when it closes.

Because of the constant tension and relaxation, the cable can wear down and malfunction, resulting in the stage light effect. This effect appears as a bright light or stage light at the bottom of the screen, or as a distorted or discolored image on the screen.

2.     Turning off of display

Occasionally, the flex wire becomes loose or cracked while remaining intact. As a result, if you slightly open the lid of your MacBook Pro, the display works fine. However, if you open the lid beyond a certain point, the display goes blank. When you return the lid to that point, the display returns.

3.     Glitches

In some cases, a damaged flex cable does not result in a stage-light effect or a blank display, but rather in graphic glitches. The display displays negative colors or a tint of a specific color. On occasion, you may notice vertical patches of varying brightness and color on the screen.

4.     Display failure:

When the flex cable completely fails, the screen on your MacBook Pro goes blank. If you shine a flashlight on the display, you’ll notice that some images and text are still visible, but they’re too dim to see properly.

Fixing Flexgate issue:

1. Prepare the Workspace – Make sure your workspace is well-lit and free of clutter or obstructions that could obstruct the repair process.
2. Power off your device- disconnect all power cords, batteries, and integrations before proceeding with the repairs to avoid potential accidents.
3. Diagnose the Issue – Examine the display to see if it is dim or if the backlight does not turn on. When these symptoms appear, it indicates a Flexgate issue.
4. Unscrew Cover Plate – To gain access to your device’s interior components, remove screws from the device’s bottom. Make sure you don’t lose any screws in the process.
5. Examine for Damage – Using a flashlight, examine the cable connecting the display to the motherboard for signs of damage or wear and tear.
6. Identify the Cable – Using a flashlight, determine which cable needs to be replaced or repaired. Take a photo of the cable before removing it for comparison purposes when replacing it later.
7. Remove the Cable – Carefully remove the faulty cable from the motherboard, taking care not to damage any other components. Once disconnected, you should be able to completely remove it from your laptop.
8. Repair or replace your cable – Attach your new cable according to Apple’s instructions, depending on whether you’re replacing or repairing your existing one. When reattaching connectors, make sure they are securely fastened.
9. Reattach Your Display – After replacing the display panel and connecting the cables, use the screws included with the repair kit to secure everything. When tightening them, use as little force as possible to avoid damaging delicate components such as screens and cables. Also, make certain that no pieces are overlooked.
10. Clean Up – Remove any excess parts or screws and store them safely. Pay close attention so you don’t leave any essential pieces behind, such as an extra screw or connector piece that you might need for future repairs. Having an organized workspace is always preferable to the risk of missing an important item.
11. Test the New Setup – Before restarting your computer, double-check all connections made with the new cable setup. When finished, restart your machine and run a quick test run for safety measures, in case any adjustments for optimal performance are required.
12. Finally, turn on your MacBook Pro and enjoy your new setup. You should now be able to enjoy a fully functional display free of Flexgate issues.
