I am having a tough time remembering how I had my basic Sony DVD, Receiver, and TV hooked up now that I am trying to put it back together in my entertainment center. I had it working together perfectly before taking it apart. Now after I have followed the directions to the "t" the digital audio from DVD to Receiver is not working properly. Coax Monster cable. Everytime I unplug it the surround sound works. Everytime I plug it in, no sound. Could my Coax monster cable be damaged? I've check it over very carefully and nothing seems to be wrong. To fix the problem I thought I would try to learn more about how the system works. For instance, if you have an S-video connection between the TV and DVD, the digital in/out connection between receiver and DVD (audio), and the RCA connection from DVD to receiver...what other RCA connections are neccasary? Again after I read the directions 10 times over it still doesn't work. Everytime I pull out the digital out connection between the DVD and receiver it does work. ???any ideas are appreciated.
