Sneaky way to get remote to control audio volume on a hotel Samsung
After an hour of experimentation I found a way to get my Roku remote to control audio volume on a hotel Samsung (HG55NT678U). I had already tried the normal method to try to pair the remote with the tv (repeatedly pressing “OK” when I kept hearing the music). After 7 code tries, the message was that the Roku remote couldn’t pair with this tv. But all the buttons worked EXCEPT the sound up/down and the mute.
Finally discovered that if I applied the volume button during the immediate startup, when “ROKU” is bouncing and dancing, for maybe 10 seconds I could set a volume level. On the left side of the screen I could see and set the volume level. Once the ROKU had fully started up, I could no longer control. This solved my problem since I just wanted to turn down the volume so hotel neighbors wouldn’t be inconvenienced by loud speaker volume. Unfortunately, if I wanted to change the volume up or down again, I would have to go through restarting the tv and again setting volume level.
