Channels & viewing

I t appears that about 1/5 of the tv picture cannot be seen. It is as though the picture has zoomed out somehow, and i cannot view/read anything on the extreme left of the screen. My other TV is just fine.

Try performing a "System restart" on your Roku device from Settings->System or Settings->System->Power (as appropriate).  If nothing changes, try adjusting your TV's zoom or picture size.
