Help My DVD player is playing through all sources

whew....you had better settle down and get a system together to troubleshoot your proble.

Unplug everything. Start with just one component. Try it with Coax and then, without changing any settings, try it with optical. One should work while the other does not.

Try getting out a piece of paper and chart your results. Try all alternatatives. go to the manual and see it any of your results make sense.
