Hi. Have an LG B6 connected right to my ATV4k and a soundbar to the tvs ARC port. I have set CEC on the ATV and it powers on and off both the tv and the SB just fine. Problem is that when the tv turns on, no picture comes. The input menu is bugged to and I have to restart the tv. This is intermittent, some times it does work fine. Anyone with similar issues?
