    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.

    I had an RCA with this problem once,,,there is a speaker MUTE signal
    for sets with an audio output, but if your version doesn't have an
    audio output there is no screen setting to change this, if it gets
    accidently set to mute. There may be a way in the service mode. What
    I did was just disconnect the mute line from the audio path. The only
    downside to this is the speaker pops on turn on and turn off, but its
    not too bad.

    Did you check for bad filter caps in the amps & output
