I have a samsung smart TV model UN65NU8000 connected to a samsung soundbar (model N550 ) . A while back I posted on here about an issue. Often after being shut off for a while, when I started the TV up the remote would be unresponsive with the light blinking for a period of time and then it would always default to TV speakers, usually with sound coming out of both the sound bar and the TV speakers creating a noticeable echo. First I was given a new remote. That did not solve the problem. Eventually Samsung support sent some TV techs out to me. They replaced a board and did some resets which fixed it until now.
As of this week it's come back and I have not been able to fix it. Specifically, it came back after my remote gave me a low battery warning and I changed the batteries, but I reset it multiple times and it still has the issue. When I start the TV up the sound devices get all messed up. I've tried resetting the soundbar and force-resyncing the smart remote to no success.
As far as I can tell the TV has all the latest firmware.
