For some reason, my TV has begun making what I can only describe as a buzzing sound while navigating the menus. This sound began a few hours ago and it happens every time I press one of the remote's buttons regardless of which button it is.
I don't know if this is an indication that some component has failed inside the TV or is being caused by a recent update to the Roku OS. It would be nice if I could record this noise, upload the file to the net, and post a link to it so someone else here can hear it and help me understand what's going on. Unfortunately, I don't have a way to do that.
Has anyone else experienced something like this? The TV is 43" Hisense Roku TV which is only two to three years old.
