Input code incorrectly three times until it does not give you the option again, then either....
Hold down the minus volume button on the set and the "7" on the remote together for about 7 seconds, or
Hold down the minus volume button on set and "6" on remote followed by minus volume and "7" on the remote.
I got this from another website, should reset code to 0000, it has just worked on mine.
