Channels & viewing

[jcom7]

Connected via a Roku stick. I can connect to the main menu and sub channel selections but when I select a particular program, it doesn't matter under what service, Apple, Hulu etc., the static image of the particular program offering is visible but when I click on any of them the stream for the program flashes for half a second then goes to a light magenta screen the audio plays in the background as though the program is streaming but no visuals. It doesn't matter what service source I have selected, it does on all available streaming services. I have not had this problem before.

The first thing to try is a "System restart" found under Settings->System or Settings->System->Power.  If that doesn't work, try unplugging the stick from the TV for a few seconds and plug it back in.  If that doesn't work, unplug the power from the TV for a few seconds and plug it back in.  Don't simply turn off the TV as that doesn't really do anything.
