Television and Home Theater

OK, I screwed up and pulled the coax cable jack out of the TV.  I tried a work around using S-video out of the DVD player to the S-Video in on the back of the TV to no avail other than sound.  Am I missing something?

I have a1984 mitsubishi rear projection tv and the sound doesn't work any more was wondering if it could be te circit board inthe rear of the tv where the speaker switches are it has internal speakers but also connections for externial speakers not even externail ones work  OR could it be the stereo amplifier? model #isVE-503  It's a video concepts model
