Soundbar issues with my smart tv

[jason13]

I had my Samsung soundbar working with my vizio tv already. The motherboard fried last week and just got it replaced today. Tv is working great but when I connected the soundbar the tv keeps turning the tv speakers off and on by itself. tried resetting the tv and still can't fix it. Anyone have any ideas?

Did you disable the onboard speakers? If that does not help, contact whoever replaced the board on the TV and see what the issue is maybe the connection on it is loose.
