    No sound on Panasonic Viera TV

    The sound on my Panasonic Viera 46" Plasma tv model TH46PZ80U suddenly went out last night. All other functions are working properly and all connections and setting are correct but no sound at all. Is there a sound card/board that can be replaced or is it time to trash it and get a new tv???

    Could use the set with a sound-bar maybe....

    PZ80 has SPDIF sound out optical, could try that....

    Need to determine whether the sound fault is in the signal stages or the output stage....

      Does that model have a headphone socket? If it does and you plug in a headphone, do you hear sound through the headphone?

        Does any one else have access to the TV? Maybe check to be certain that someone didn't turn the speakers off.
