Found this on another site and it worked, had to switch back and forth a few times but it worked........
I have a Sharp LC-46D43U LCD TV. I think this is a entry level for
large lcd tv's. With the volume all the way up at 60, my wife and I
could barley hear the tv. I was playing around in the menu and some how
have the volume at almost twice the volume. What I did was:
Go into the menu
Go to option
Go to output select
and change from fixed to variable and back to fixed. You may have to do this a few times.
Sometimes the volume goes loud after 1 try and sometimes it may take 10 or 20 tries.
But if I change any settings, even the channel sometimes the sound goes back down to where it was.
Has anyone done this, did it work for you. I don't know very much about electronics and I have now ideal why this happens.
I wonder if this is just something with my tv.
