Trying to get volume control to work on Direct TV 66rx remote with new TCL 6 series TV. When go through setup process for the TV via the Direct TV remote, get to a screen with manufacturer's options, like a hundred or more, but no TCL? I've seen various codes offered when I search google but I don;t ever get to a place that I can put in a code. How is TCL not available on the drop down list--there's **bleep** like sears and wards that don't even make tvs anymore. Any advice or am I stuck just using two remotes?
