Why is there no picture on my Dish TV Set-top box?

If your Dish TV S7090PVR set-top box shows no picture, first check if it is plugged in and turned on at the wall. Look at the front panel; if it's not illuminated, there's a power issue. Check the power socket and plug. Also, ensure your TV can display the current output format. Go to Main Menu Installation - System Setting - HD Resolution and set it to a resolution your TV supports. You can view this using the composite output.
