Do u use the tv remote or the Dish remote? As far as I know, u can not push just one button and turn Joey (or Hopper) and tv on. U need to push either top left button (on remote 52) or Select button (for Satellite equipment). I have Vizio brand tv and soundbar in my kitchen. When I turn tv on, I get close to tv and hold the dish remote with a 45 degree angle and push tv button. (The reason is the soundbar blocks the bottom of tv. Using the remote from far only turns the soundbar on. )
Then, both tv and soundbar r on. The next step is turning Joey on. If u r having an issue with remote, u can always try to pair them under Settings.
