A:AnswerHi.
If you have made sure both the TV's volume and the Dish's hopper volume are at reasonable levels and after checking that your connections are well plugged-in nothing works. Please, contact us on the link below my signature for further assistance on this and step-by-step troubleshooting.

Use the included remote to control your Fire TV Edition television.

A:AnswerUnfortunately, the app Spectrum TV is not available for the Fire TV Edition experience.
You will need to connect an Spectrum Cable Box using an HDMI cord to watch cable channels.
Also, you can connect an antenna to watch free over-the-air broadcasts from your local channels.
