Hello, was there ever any resolution to this? We are having the same issue on the HDMI arc. We started using optical for audio. But now we can’t tun everything on with one remote. We have a 2017 model. Very frustrating for such an expensive tv.
Nice soundbar! My idea is probably too simple. When setting up my LG TV & LG soundbar I couldn't get any sound via ARC either.
My soundbar has 2 HDMI connections one marked sound in and naturally, I connected the TV ARC port to the soundbar port port marked Sound In. I couldn't get any sound unless I used the optical connection. To my surprise, I found that if I used the other HDMI port on the soundbar it worked perfectly! This still seems wrong to me but everything works and sounds good so have not made any inquiries.
I had the same problem with Netflix restarting but I realized the problem started after I downloaded the YouTube app from the store so I deleted the YouTube app and it has soled the problem of my Netflix restarting I hope this may help anyone
Our telly is less then two years old. First time we purchased LG products ( never again)
My telly is doing something similar. Entire screen gets vertical lines on it and goes away if I turn telly off.
Had similar problem last year and it was repaired under the five year warranty. Going to call warranty people again to have it repaired. Rubbish telly if you ask my personal opinion: we are light users and may watch 4/5 hours a week! I’m going to try and ask for refund or a replacement. Pointless having an expensive large screen tv when you cannot use it properly.
