My TV volume went to very loud and cannot be turned down. Why?

There are any number of reasons this could happen. Unplug your TV for a few minutes, then plug it back in and see if that fixes it. Otherwise, if the TV is under warranty, contact the manufacturer or the place you purchased it from and see if you can get someone out to look at it.

You could also try turning it up as high as it will go, then try reducing the volume. Sometimes that helps.

If not, contact the manufacturer, or give it a good whack. ;)
