Coloured lines on an iPhone screen: causes and fixes

Green, pink or coloured lines on an iPhone screen usually mean the display panel or its connection is damaged. Take a screenshot: if the line is not in it, the screen is the problem. A restart and an update rule out software; if it continues, the screen is replaced.

Cep Market Repair TeamIn Kadıköy since 2006
Key points
  • Coloured lines usually mean panel or connection damage.
  • If the screenshot has no line, the problem is the hardware.
  • A restart and an update rule out software.
  • Drops, pressure and liquid are the most common causes.
  • Back up your data before the repair.

01Software or screen?

  1. Take a screenshot. If the line shows in the screenshot, it is software; if not, it is the screen.
  2. Force restart. Volume up, volume down, then hold the side button.
  3. Update. If iOS is not up to date, update it.
  4. Back up. Back up your data before the lines spread.

FAQ

Frequently asked questions

01

Why do coloured lines appear on an iPhone screen?

Usually a drop, pressure or liquid has damaged the display panel or its connection.

02

Do coloured lines go away by themselves?

If software is the cause, a restart or update can clear them. If hardware is the cause, they stay and often spread.

03

How can I tell software from hardware?

Take a screenshot. If the line is not in it, the problem is the screen hardware.

04

Will a screen replacement delete my data?

Data is usually preserved during a repair; still, you need to back up your data before the repair starts (backups are the customer’s responsibility).

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
