01 · Megasat HD 7 Combo · Version 2.2
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 / LNB
Match HD 7 Combo and its Version 2.2 (September 2025) manual; record both Softwareversion and Software Ver. in MCU. LNB IN/DVB-S and RF IN/DVB-T/C/DAB are different inputs. The 13V, 18V and 22k LEDs show LNB feed settings, not satellite lock; ERROR indicates a cable/LNB fault such as a short. Record the exact satellite/transponder, Power Unit, CNR, CBER/LBER, feed current/voltage and message before changing anything. A blank Live TV list is not the same as absent satellite measurements. Signal tone and key tone can be disabled independently. Preserve STORE screenshots and saved data. Factory settings deletes saved data: do not reset, flash, change motor/feed settings or reconnect a live feed as a test; seek qualified installation service.
03 · 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.
