I have a UN65J6300 TV that I purchased a couple of years ago. I love the TV, but just recently hooked up a Chromecast to it and began using the Anynet+ (HDMI-CEC) feature in order to control the TV via Google Home voice through the Chromecast. After plugging the TV in initially, Anynet+ will work for a short period of time (1-2 hours) but then it stops working. To get it working, the TV has to be power cycled (unplug/plug it back in). Needless to say, this defeats the purpose of using Anynet+ to control power to the TV. Is there a fix for this or is this a hardware flaw in my set?
Is everything up to date on the television? Is there a sleep timer on the chromecast currently?
