Work through these checks
Stop the external supply
Use the meter’s external power control to disable LNB feed. Switch off connected system supplies before removing coax.
What the result means: Do not reconnect repeatedly to force the warning away.
Inspect the isolated lead
Look for loose braid touching the centre conductor, crushed cable or a damaged connector. Replace an obviously damaged test lead.
What the result means: This checks an accessible component without opening equipment.
Separate instrument and installation
With RF lead disconnected, check whether the warning remains. If it clears, ask a qualified installer to isolate the cable/LNB/distribution branch before restoring feed.
What the result means: Persistent unloaded warning points to meter support, not a new dish.
When to stop and get help
Stop for damaged insulation, water, heat, repeated protection alarms or any shared-system uncertainty. Do not open the meter or change building distribution wiring.
What to tell support
Record model, firmware, exact warning, power setting and whether it remains with RF disconnected.
Common questions
Does SHORTCIRCUIT prove the LNB is faulty?
No. The lead, connector or distribution path can also cause the problem. Isolate the fault before buying parts.
