I have Logitech Harmony remotes with all TV's that run macros to get the right platform going on the TV and the Receiver (Cable Box, Roku, and in one case, an XBox). There is no hope of anyone but me troubleshooting it if they don't have it pointed straight at the TV properly for the macro to run its course.
To be fair, I set up it, so I know how all the wires are run. I had AV guys set up our outdoor speakers many years ago. Had them come back for some other work a few months later and had them show me how it was set up yet again - but somehow I can't get those ****ing outdoor speakers to work to save my life...
Logitech Harmony remotes are my bane. I never get them to work like they should.
