Welcome to the site.

 

First 3 things could be, your HMI module is going bad, you have a bad battery, or a bad ground somewhere on the truck.

Did you ever figure out what this problem was you were having?   My truck is doing the exact same thing.  Every time I put blinker on screen goes to green, and back up camera is not working.   Also screen blinks right around 12-15mph every time you start or come to a stop.   This is the only other post I've seen with this problem.
