Panasonic TH-50PX75U
 

Hello! I am wondering if anyone knows which board controls the audio in this old plasma TV. My son got it from my sister, after it sat for a long time to use with his video games. It worked for a few days, then suddenly one day had no sound. Checked settings, left unplugged for a few weeks, tried different inputs including the TV tuner itself ... no sound, and no "click" noise when adjusting the volume (not sure it does that but assume it does. Picture still good. Worth repairing?

Could being left outside overnight after playing one night have shorted something from moisture?

Thanks, as always

The audio sections of most of these types of sets are on the main board. If a board is needed, search for the part number that will be stenciled on the actual board. Panasonic plasma main boards were always the hardest to find and more expensive than most other brands. Check both speakers for continuity, I've had customers who had one speaker fail and then to compensate, ran the volume louder and ruined the other. Might be very likely if said set was used for video games.
