The above unit has no audio.This is on both A/V i/p's & tuner.Replaced IC401=LA4270 & AN5836=IC4101.If I inject audio on I/P pins 2 & 5 on the audio o/p IC401 my audio is OK.Got a schematic from the Hitachi website but not the exact model I wanted,so using one that 's close .This audio comes & goes to other ic's on this model.Can any Hitachi people steer me in the right direction....TIA...
