Query: No Mute?!

As impossible as it is to believe, there is no mute button on this unit. Fortunately we figured this out before setting up the TV and saved the necessary effort of extensive repacking before returning it to the store. The mute button on the remote is more than just a convenience - it is the manufacturer's sole effort to prove they are on our side in the continuous battle between ever-intrusive advertisers and ad-saturated consumers. Obviously Toshiba has moved to the dark side in this battle.
