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.
