This pisses me off lol. I went to settings already and turned the LED Indicator off, but this only turns the LED standby light off when my TV is powered off. I use the audio only option often to go to bed, and even with the LED indicator selected as off, that stupid little light comes back on. Is there ANY way to turn that light off at all times? I might just tape it with electrical tape at this point.. Excuse any errors, I'm on mobile and woke up to that dumb little light.
As far as I know, the LED indicator will turn On and Off in a pulse pattern during Audio Only Mode regardless of whether the LED setting is set to On or Off. The way the LED turns on during Audio Only Mode varies between models but I think the light stays on during Audio Only Mode in all/most models. I guess if it's really distracting you at night, best is to tape it...
