Work through these checks
Compare national and local channels
If national reception works but locals fail after travel, ask DISH to check the current local-channel area.
What the result means: This points to a narrower service issue.
Check sky and MAIN wiring
With receiver power disconnected, use MAIN to SATELLITE IN and hand-tighten coax. A stable, reasonably level ground location needs a clear southern sky. Keep cables away from traffic and trip hazards. Roof-mounted installations need a technician.
What the result means: Record obstruction or wiring changes.
Rescan after movement
Keep the antenna stationary throughout the scan. Moving it during or after scanning requires another scan. A new receiver also needs account activation; a scan alone does not activate service.
What the result means: For 004 after changing channel, inspect obstruction toward the newly selected satellite. Allow the guide download to finish after acquisition.
When to stop and get help
Use safe ground access only; disconnect receiver power before checking coax. Do not open the dome or climb onto an RV roof.
What to tell support
Save the error, channel and whether the antenna moved.
Common questions
Why test a new receiver before leaving phone coverage?
Initial activation requires a DISH call. A completed antenna scan alone does not activate a new receiver.
