You didn't happen to replace the MCU in that unit did you? I just fought a
tough Panasonic and it turned out the IC was a mismatch. All the numbers
were the same on them so must have been factory mislabeled. Luckily the old
MCU was OK and only the reset IC was bad. When I reinstalled IC the sound
menu had changed( it also had that AI listed) and the sound was then good.
Just a thought. We fought ours for 4 weeks of ordering parts and
schematics.
