I have this wonderful 37" Panasonic plasma tv with beautiful pictures but no sound. For a few weeks the sound went in and out over different days but now has no sound at all. The DVD and videos work perfectly with sound.

Re: Panasonic TH-37PD25 plasma has no sound
If all of your connector cables are in good standing and your input/output ports are hooked up correctly, this may be an audio defect developing in the processor board. I can walk you through some steps to confirm this problem.

Are the speakers' cables connected correctly? (p. 37) Is "Sound Mute" active? (p. 13) Is the volume set to the minimum? Is "Speaker output" set to "Off"? (p. 22) Change "SAP" settings. (p. 16) Check "HDMI 1 in", "HDMI 2 in" or "HDMI 3 in" settings. (p. 22)
Hope this helps, page# refer to your manual.
did you check into the settings on the cable box and the tv? make sure you dont have a side by side or picture in picture function that was accidentally hit. and since you said on a game system everything is fine, i would check into the settings on the cable box. is the picture the same in both panels?
