I have had this issue for 9 months with my Roku ultra and Samsung tv. I have gotten 2 new Roku remotes and it keeps happening. So frustrating. But I recently purchased an off brand remote for $12 that wasn’t on wireless and it works great. Not one issue. Yes it doesn’t feel as good in the hand as the Roku model but everything else works great and makes watching tv pleasurable once again. I recommend this as a viable solution.
I had this issue with a Roku Ultra and LG C2. Changing the remote TV pairing from IR to CEC resolved it for me.
I think sometimes when you hit the mute or volume buttons on the Roku remote it does a long hold for some reason. That explains this issue and also the issue where sometimes pressing a volume button will cause the volume to continuously go up or down (as if you were holding the button down, even though you just click it).
I have have a similar problem with a just purchased LG 4K and Roku Ultra.
Pushing mute multiple times brings up a sidebar screen with menu selections for "AV Reset", "Auto Tuning", and "LG Remote Service" along with a few toggles.
Pushing the mute 3X in a row quickly is a "feature" to turn on this service menu which isn't attached to the main menu tree since it contains items that may be more magic than an average user should be playing with.
Another site had the following fix:
1. Press the settings button on the TV remote
2. Scroll down to "All Settings" select
3. Scroll down to "General" and press right
4. Scroll down until you reach "Quick Start", toggle it to the off position.
The post author said this process or a close one should work on LG TVs. I haven't had a chance to test it yet because I don't have access to the TV right now.
I would guess that other TV manufacturers might have a similar "feature" and some hunting in depths of the setup screens might also disable it.
I'll report back after I get a chance to try the fix.
