You can accomplish this by unpluggin the tv for 4 hours. When you power it back up the internal software will revert to the original factory defaults.

Your optics engine has failed in the set. One of the LCD's usually the blue has come apart and is smearing. The only way to correct this is to have the optics engine assembly replaced.
