SO THANKFUL for the ambient sensor advice
You have no idea how thankful I am for the ambient sensor advice! I was about to go nuts... Got new TV, a Toshiba at first, got a new remote, didn't get it to work... returned the Toshiba TV to get a Sony and see if that works... no luck... until I finally came across this post with the ambient sensor.. Turned it off and it works just fine... FOR NOW... I hope it stays this way... this made my day. Thank you!
