Half of my screen is covered with colored lines

Hi,

The screen is covered on one side by colored lines. If I accurately guess where input buttons are I can still navigate via touch screen so that is still working. I just cannot see the entire desktop because of the colored lines.

The most interesting is that when I start the camera or when i start a hd video (in landscape) the color lines just disappear and the screen look perfect until I close the camera or video. It looks like on gpu the screen looks perfect.

I already tried "Force GPU Rendering", I opened my phone and verified the display connector unplugging and plugging it with no result.

Is possible to set the phone to use only the gpu?
Is that even possible?

My phone is a Galaxy S4 rooted with kitkat 4.4.2


Regards,

Jonn

Do you have any third party accessories, like an extended battery, or a bad charger? Have you tried doing a battery pull? It seems like the voltage given to the screen is incorrect, and that the extra gpu needed for running the camera or videos dynamically lowers the amount going to the screen, otherwise, you did something to it like rooting and installing an incompatible kernel.
Good luck!
