Work through these checks
01 · OCTAGON SF8008 V3 4K SUPREME COMBO
Match the exact model, product code and manual edition. Record the existing connections, status indicators and displayed error without changing them. Preserve settings and stored data; do not reset, flash software, format storage or alter wiring as a first check. Keep account details, device identifiers and precise location private.
02 · DVB-S2 / DVB-C/T2 / ANT1&ANT2 / HDMI / ETHERNET / RECOVERY / RS232 / Hard Disk > Initialization (Format Hard Disk)
Confirm SF8008 V3 4K SUPREME COMBO, not the Twin Sat version or an older SF8008. The original manual distinguishes DVB-S2 satellite input from DVB-C/T2 cable/terrestrial input; ANT1&ANT2 are Wi-Fi antennas, not dish inputs. If the receiver menu is visible, record which reception path fails before changing settings. If nothing is visible, first compare the TV's selected HDMI input with the existing HDMI connection and note the receiver display/status LED. ETHERNET or Wi-Fi connectivity does not prove satellite reception, and a satellite picture does not prove IPTV connectivity. Preserve the exact error, current channel and working services. Do not use RECOVERY, RS232, software flashing, a channel rescan or Hard Disk > Initialization (Format Hard Disk) as a first fix: initialization erases storage. Do not open the case or move live antenna cables; isolate power before any approved connection work. The manual contains inconsistent memory specifications, so do not select firmware or replacement parts from those figures. Escalate persistent faults with the exact model and existing evidence, keeping identifiers private.
