Unlock my sharp 21G-fx10 TV

Unlock all of the channels on the TV by entering the factory-reset code. There are three main reset codes that TV manufacturers set. These are 0711, 6688 and 3308. Try each one until you find the one that works. This will reset the TV to original factory settings. When you do this, you will loose any information that you have stored in the TV, such as favorite channels, automatic timers and the clock. You will have to go through the full initial set up.
