How to fix an iPhone with half a screen showing a different color? I have an iPhone 6. It screen was changed about 10 months ago and its battery was changed about 1.5 months ago. Yesterday, I suddenly noticed that half of the screen is darkened and with yellow-ish vertical lines. As far as I can tell, there was no immediate damage that was connected to this (i.e., no drops, or water damage, etc).

This appears to be a hardware issue and I don't know if it is related to either of the fixes.

Here is an attempt at a screenshot (which is taken from my macbook):



Does anyone have an idea what this problem is and is there an easy way to fix this? Do I need to purchase another screen?

I don't live in North America, so getting a screen replaced will cost more than $200USD, so I would like to avoid that.
I would also try a full factory reset, like IconDaemon suggests. If that doesn't improve your situation, you have the following choices:


Go to an official Apple store or a premium service provider to exchange your screen (this will cost you between 100 and 300$ depending on your location)
Go to an iPhone doctor or clinic which replaces the screen with a cheap aftermarket china one (Be very careful with this, most of the screens have a very bad quality and you can't get support from Apple afterwards. To check, if a screen is genuine, there should be no yellow glare and you can press firmly on the glass without damaging the display)
Buy a broken iPhone online and change the screen yourself as this tutorial on ifixit states: iFixit - iPhone 6 Repair
