I have a Panasonic Double din thats not real old but Im not the orginal owner...Everything is good on it except for when I play dvds and cds! Sound works fine with no issue what so ever on the radio but when I switch over to dvd or cd all i get is the video with not one sound!...Checked the wiring and everything looks good but I am stumped! Anyone ever heard of sending those things back to panasonic for repairs?

 

The model number on the it is cq-vd6505u...Hope you guys can help!
