    Someone must have seen this common problem! I checked for bad filter
    caps in the amps & output..all ok! This occurs when you repair a set
    for bad vertical. In the customer menu, there is no option to do
    anything with the sound.

    JVC Model # AV-27820 Chassis # A 53, or Sears (made by JVC) Model #
    57-14367. This (no sound) issue sometimes happens after doing the
    typical vertical repair, or after replacing the tuner, that was
    damaged. No sound, & no way to turn on sound in menu. Has anyone seen
    this? It's getting common for me, but I never get it solved. There is
    gain from the audio output
    ic. Seems like an EEPROM, or Micro issue! Thanks, Dani.

    Usually a mute problem, sound muted inside the IC by transistor that
    has been switched by the Micro.
    but wicking out the mute pin should bring back the sound.
