Work through these checks
01 · ID
Match the exact hardware, tuner standard and manual. Keep LNB feed and TV/AV display connections distinct. Preserve saved channel plans and transponders.
02 · RF
Read level, quality or error measurements together with lock and the selected transponder. Compare only unchanged units and settings at the same measuring point. Wrong satellite data or an unsupported standard can make a working feed look faulty.
When to stop and get help
Stop for damaged cables, unexpected voltage or short-circuit warnings; ask a qualified installer or meter service. Do not bypass protection, change LNB power, DiSEqC/SCR, motor settings, calibration or firmware, or reset to test.
What to tell support
Save model, manual edition, software, measuring point, satellite/transponder, units and the original screen or error. Keep site identifiers private.
