Marantz sr7200, paradigm titan v3, bic f12... Getting static out of both speakers. Turned SD on and static stops but no sub either, yuck..i turned SD off and static returns but still no sub, yuck. Sub connected via RCA preout sub output. Put the receiver on the monitor and my speaker setup has changed from just the fronts set to small and sub set to yes to all speakers set to on and large, yuck. Also not able to select speakers to change them back to the way they were with the remote. Receiver also powers of on its own accord lately. This receiver has been treated with respect as well. Any glimmers of hope are much appreciated as this current situation makes me feel like I need a shower.
