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
