I don't know how long this has been going on, but I just noticed this today. About 20 minutes into Planet of the Apes is when I really began realizing that there wasn't any sound coming out of my center speaker. I looked at the receiver and all of the speaker icons were lit up except for the center. I checked my connections, and everything is fine, and when I go into the speaker menu the center is set to large and the icon is there, but a few seconds later (when the main info display reappears) all the speaker icons pop on again except for the center.
I tried restarting the DVD, turing off, then on, the receiver, tried a different DVD, still same result. If I switch to another input, say video 1, the center icon will show along with the "pro-logic" icon, then go back to DVD input, the red "digital" will show up, but no center.
Has anything like this happened to anyone else? Is there any quick fix? Thanks for any suggestions or info!!!
