This TV does not use an IR remote, it does have an IR sensor but its located where the power button is facing down. I have also found that by keeping everything RF my battery lasts much longer than when I used to have a mixed environment.

Last night I had my AVR and TV not respond to the macro, so I am wondering if this is more of a 300 vs 350 issue as I never had problems with the 350 until it totally crapped out. That would be odd though, since its consistently the TV. RF antenna shows no interference but it is literally right next to a Ubiquiti AP crammed into my built in A/V cabinet.
