UI flashes on and off with Rivo

I just received my new Rivo and have it set up and working with one caveat. The UI when displayed on my TV blinks off and on at varying frequency. Sometimes it will stay on for 20-30 seconds, other times off and on every few. My TV is an LG UN7300PUF. I was asked to post a video but as a new user can not.
TIA!
