From brightness and color adjustments on the picture to sound adjustments to the bass and treble on the sound, the Sharp Aquos television can be adjusted in many ways to suit your needs through the TV's built-in menu system. If you make changes you cannot remember how to undo, or find your television no longer suits your requirements, you can reset the Aquos to its factory settings.
Press "Menu" on the TV's remote control and use the arrow keys to scroll to "Setup."
Scroll down to "Reset" and press "Enter" on the remote.
Select "Yes" using the arrow and "Enter" buttons at the "Return To The Factory Preset Values" message.
Select "Yes" using the arrow and "Enter" buttons at the "Now, TV Will Restart Automatically. OK?" message.
Wait while "Now Initializing..." appears on the screen. The TV will power down and turn back on when the reset is complete.
