Sound bar: MS750
Issue: The sound constantly stops/switches from sound bar to TV speaker and then back again. I have hooked this sound bar up with bluetooth, and it will work for a while, then go back to tv speaker, then start working again. All without any consumer interaction with the remote or sound volume (aka we are watching a movie and it just switches).
I then switched to optical cable...and it does the exact same thing.
I then switched to wifi connect....and it does the exact same thing.
I then updated the firmware in the sound bar, and it does the same thing.
I then looked to update the firmware on the TV but it says it is up to date.
I then thought I had a hardware problem, so I connected my phone to the sound bar with bluetooth, it played for 4 hours without a hiccup.
I then connected a reciever to the sound bar via optical cable, it played without a hiccup as well.
I have had this sound bar for 3 years. It was previously paired with QN75Q7F using bluetooth and never had an issue so I have to assume at this point I have some issue with the TV. Looking for advise.
PS in the time it took to write this post, the TV switched from playing through sound bar, back to tv speakers, back to sound bar.....twice.
Solved! Go to Solution.
Have you attempted a factory reset of the tv? If this does not help I recommend letting a service technician have a look. Send your full model code and serial number via private message to get started.

I have now performed a 'factory reset'....what a pain having to go through and reset everything up. Had an annoying issue with the screen always going dark on me regardless of what picture mode I set....then I found the super secret "eco settings" menu that I just turned everything OFF on.
TV has run for about an hour connected through blutooth without switching audio, will keep an eye (ear) on it for a few more days and see if that has really solved my problem or not
Update to this thread. the solution was not found in 'reset' or software update or some setting in the menus. Repair company was out today and put a new board in the TV. Will update it I see the issue come back.
