How to adjust the pictures in the tv to make it clear?

The single most effective thing the owner of a TV can do to improve the picture is turn the SHARPNESS control all the way up. This action will make the vertical lines that make up the picture look sharper thus the picture is sharper. If the power goes off or the set is unplugged the setting will revert back to the factory setting (in the middle) so you have to reset it again.
