How it connects
Compare the connected LNB IN 1 / LNB IN 2 sockets with the existing Operating mode: Tuner 1, Tuner 2 or Twin Tuner. Under Signal, record strength and quality separately for each tuner; a working tuner does not prove the other feed works. Record Installation > Information and scheduled timers before resets. Missing Mediaplayer options can mean no suitable USB storage is recognized; Formatting data volume erases files. Match the model, product code and manual edition on this page. Photograph existing connections without changing them. First separate TV input and standby problems from missing satellite reception. Preserve the channel list and antenna settings; do not factory-reset, flash software, rescan or rewire as a first check.
