I have the onn 4K LED Smart Roku TV and picked it up as a Black Friday deal. Everything works fine, except on some occasions, I'll turn the TV on and the audio doesn't work. I have to unplug and replug the TV in order for the sound to start working again. Anyone know how to fix this issue? Or why it is this way?
I really have no idea what causes the problem in the first place. These things are just special purpose computers, and like their brethren, sometimes you just need to reboot them to get out of problems.
If unplugging/replugging is a pain, it may be easier time to just restart the set via the on screen menu: Settings > System > Power > System restart
