Random colors on screen

Hi there, my parents recently found their first iPhone and gave it to me, they said there were no issues, but when I charged it, the screen started showing random colors, I could tell it was responsive as the brightness was changing in the place where the slide to unlock text is. I’m able to hear sounds from the phone when clicking the emergency call button and tapping where the numbers would be. All help would be appreciated!

This issue is usually caused by a damaged screen or loose screen connector

You will most will most likely need to replace the screen but I would open it up first and try reseating the display connector by following this guide

iPhone 4 (GSM/AT&T) Screen Replacement

If reseating doesn’t work you will most likely need a display replacement which you can find liked below

Hopefully this helps

Any questions please ask

Hey there @HelloMacOS I tried reseating the connector, the screen started to show properly in the center, with some random colors around the edges of the screen, I then tried signing in and the screen started showing colors again, I even cleaned the connectors, it still didn't work. Thanks for your help!



Your most welcome

You will most likely need a new screen:-)


Oh ok, thanks again!
