I have a similar situation. I own a fitness center and have 4 TVs working off of 2 receivers. I need all receivers to be UHF. For whatever reason, my remote for TV #1 got changed to an IR and I don't know how to get it back to UHF. All 3 other TVs are UHF. Doing what the Duluth guy said doesn't change my remote to UHF. Please help.
