I don't know what I did differently, but the press mute 5 times button DID get me a mini service menu where I could turn off the screen saver. If it doesn't work for you, try with the home menu up on the screen, or right after the TV turns on.
I've got my ThinQ and Google Home apps and Google Home speakers set up to turn off my LG C1. But they won't turn it on, I guess because the TV isn't listening for commands when off.
I expected that enabling these
Settings|General|Devices|TV Management|Quick Start+
Settings|General|Devices|External Devices|TV On With Mobile|Turn on via Wi-Fi
would do it, but it did not.
OMG I just discovered that Alexa turns on the TV...and I never even had to open let alone set it up in the Alexa app!
Recently my LG C1 has been pausing on its own and going back to the profile selection screen while using native apps. This issue occurs while using Netflix, Disney+, Paramount+, etc. I tried using my Firestick and it kept pausing my program. I tried a hard reset and that fixed the problem for 2 days before it started again with Disney+.
I need a fix for this issue ASAP.
