Work through these checks
01 · Megasat HD 4 Combo V2 · manual V3.0
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
Use only HD 4 Combo V2 instructions, manual Version 3.0, August 2026. LNB In is satellite; ANT In is terrestrial/cable. Record the satellite/transponder, strength and quality, PWR/CNR/CBER/VBER, and hardware/software versions. A flashing warning triangle can indicate an antenna short circuit. F1–F4 depend on the current screen. Check Auto Standby before treating an automatic shutdown as a power fault. Preserve lists and settings: Reset and Factory setting erase data. Do not change feed voltage, command motors or move the dish as a diagnostic test; refer cable faults to a qualified installer.
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.
