[SOLVED] Continuous Rainbow Animation on right side of screen

[Nachteule]

@onlyindian

Before you continue solving issue 2, you have to eliminate issue 1. I agree with @IriDium, you have serious power issue and a little change of broken rpi2 [1]. Try to change PSU first.

Do you have additional devices connected to your Pi2?

[1] At one of my development/testing system (RPi3 and sometimes RPi2) I'm using 5V/1000mA power supply with short power lead and never seen this rainbow square
