Often - I will be watching a show via my Roku Ultra (does not matter what eg Youtube TV, Netflix, etc) and the power and volume buttons for my Samsung TV will stop working. This requires me to re-pair the remote and the TV ... this happens a few times each week and it VERY annoying. Any ideas??
Is your problem with a Roku Voice Remote that intermittently loses ability to send infrared Volume, Mute, and Power commands to the TV?
I've never experienced this problem with any of my Voice Remotes, but it has been reported that updating to the latest remote firmware version can fix the intermittent IR command problem. This can be done via a Roku "secret menu".
Caveat: So-called "secret menus" are not officially supported by Roku. They may not work with all Roku models, and they may be discontinued at any time.
Go to the "secret" Platform Menu. To do this, hit the these buttons in sequence: Home five times, FF, Pause, RW, Pause, FF
Go to RF Remote Menu
Go to Over The Air (OTA) Update Men
Go to OTA Firmware Update
Update the firmware
Exit
