I assume the Panasonic is a TV. I have never heard of green audio outputs. Audio outputs should be red and white (for RCA plugs). There are adapters available that convert the yellow, red and white component outputs to HDMI. You can get them at GameStop (I bought one recently to connect a game system for my daughter). If you have a TV converter box from your cable or satellite provider you might be able to connect the audio out on the cable box to your Technics receiver and run a HDMI to the TV (be sure to turn off the TV's internal speakers through the TV's menu) for video.
