Steps

Goal: Confirm the symptom, check input and receiver, then rule out connections and signal issues.

Check input and receiver

Goal: Confirm the correct input is selected and the satellite receiver is on.

  • Use the TV remote to select the input where the satellite receiver is connected—HDMI 1, HDMI 2, etc.
  • Confirm the receiver is powered on and not in standby. Wake it with the remote or a button on the receiver.
  • Good: Correct input selected and receiver is on. The signal appears. Done.
  • Bad: Still no signal—proceed to Check coax and dish.

Check coax and dish

Goal: Rule out loose coax and LNB signal blockage.

  • Check the coax cable from the dish is firmly screwed to the SATELLITE IN port on the receiver.
  • Check the dish from the ground for snow, ice, leaves, or debris. Do not climb on the roof.
  • Run a signal test in the receiver menu—Settings, System Setup, or Signal.
  • Good: Coax is snug and signal test shows signal. Proceed to reseat HDMI and power-cycle.
  • Bad: Signal test shows 0—clear obstruction if safe, or call your satellite provider. Do not adjust the dish on a roof yourself.

Power-cycle

Goal: Reset the receiver and power-cycle HDMI handshake.

  • Unplug the TV and the satellite receiver from power. Wait 30 seconds. Plug both back in. Turn on the receiver first, then the TV.
  • Good: Power-cycle fixes the issue. The signal appears. Done.
  • Bad: Still no signal—call your satellite provider. Call a TV technician if the receiver works on another TV.

When to get help

Call your satellite provider if:

  • The coax is connected, the receiver is on, and the signal test shows 0. They can run diagnostics and schedule a technician for dish alignment.

Do not climb on the roof to adjust the dish. Call a professional.

Call a TV repair technician if:

  • The satellite receiver works on another TV but not this one, or no HDMI input works on the TV.

Verification

  • The TV shows a picture from the satellite receiver.
  • The correct input is selected.
  • The coax and HDMI cables are firmly connected.
  • The receiver is on and channels tune.
  • The signal test in the receiver menu shows adequate signal.
