Hi there

There are no other settings on the TV for audio description im afraid - if its ONLY 1 specific channel, then its a channel issue.  If its audio description is still on for ALL channels, after setting it to "Normal", then it might be something else.

Is audio description only on 1 channel or multiple channels?  Also, are you going through the TVs digital tuner or another external box?

What happens if you go to the "Subtitle Settings" - is it OFF?

Cheers
