Long time reader (years!) on avsforum, but finally decided to sign up to see if anyone else has experienced this.
I recently bought a pair of powered speakers (Kanto YU5) to replace the current sound bar I have. I use the optical output from this TV, plugged directly into the speakers, and it mostly works.
From my PS4, or using the onboard Netflix app, everything is all cool, sounds awesome!
But I have an antenna plugged into the TV for OTA HD, and when I use these new speakers, all I get is screeching and squealing sounds. Same thing happens with some digital files when I have a USB drive plugged into the TV. These issues do not happen with my existing sound bar.
Has anyone else had similar issues with the optical output from this model of TV? I'm speculating it has to do with the format of those particular digital streams, but has anyone else has this issue? and maybe have a suggestion to fix it? maybe something in the service menu? (Tried turning Dolby on already).
