Sorry but just sharing that when I did this pairing I had to pop in fresh batteries and the remote was withing inches of the front of the set. Maybe it was that set but the pairing failed at 10 feet away.
I was setting up my new T.V. made a mistake missing one number and the tvshowed a blue rectangular showing an check mark Dont recgnize model.
Spent hours but can't get that sign off, I even went to menue and set the TV on default.Everything cleaned up but that check mark
Thanks for the help
