I'm trying to figure out why a home-theater system (in this case, actually a motorhome-theater system) is no longer working correctly. The HTS is a Sony BDV-280 and the TV is a Sony 40BX420. They are interconnected with an HDMI cable, and a digital optical cable (DO cable) which, according to Sony's Quick Setup Guide, is required to "enjoy TV sound".
Although you use to be able to hear TV programs through the HTS, that is no longer the case. For all other input sources on the HTS (e.g., FM and Blu-Ray), there is perfect sound through all the speakers. Although there doesn't seem to be any special configuring required for TV-generated sound, there's no longer any sound making its way to the HTS's speakers. I believe it is supposed to be as simple as having the TV input set to a TV source (e.g., antenna) with the HTS's input set to TV, and of course the volume at a high enough level. I can't find any other setting on either component that would affect the HTS sound coming from TV programming.
I've checked the DO cable and it is securely plugged into both the BDV-280 and the 40BX420. How can I determine if it is a problem with the cable, one of the components, the setup, etc.?
I did check the DO cable at the HTS end and there is a red light. Is that a reliable indicator that the cable is good and thus would mean that one of the components has gone bad?
