Flexgate is the informal name for display flex cable failure on MacBook Pros (especially 2016–2019). Customers describe it as pink lines, stage lighting, flickering when the lid moves, or a screen that went black overnight.
Cable vs panel vs board
| Observation | Likely cause |
|---|---|
| Torch shows desktop; no backlight | Flex / backlight path (Flexgate) |
| Pink lines change with lid angle | Flex cable |
| Shattered glass / ink blotch | Panel — needs display replacement |
| External display also corrupt | Board / GPU path — needs logic diagnosis |
Models most affected
A1706, A1707, and A1708 MacBook Pros are the classic Flexgate machines. Other years can fail similarly. Bring the serial or model identifier so we stage the correct cable.
What repair looks like
- Torch and lid-angle confirmation.
- Open display assembly; inspect flex path.
- Cable repair or partial display service when the LCD is healthy.
- Full panel only if the glass or LCD is damaged.
Flex repairs typically start from ₹4,500 (backlight) or ₹6,500 (display flex). See MacBook Flexgate repair in Chennai or compare with full display replacement.
Frequently asked questions
Why does my MacBook have a pink vertical line?
On many 2016–2019 Pros, a fatigued display flex cable breaks backlight or data lanes. Lines that shift with lid angle strongly suggest Flexgate.
No backlight but I can see the screen with a flashlight — what now?
That usually means the LCD still works. Do not order a full display yet. Book a Flexgate diagnosis — cable repair is often enough.
External monitor works. Is my graphics chip dead?
Usually not. If HDMI/USB-C output is clean, the GPU path on the board is fine and the fault is in the internal display path.
