Isn't this where you enter the service mode by press/release mute button on the 
 remote...press mute and
hold while pressing menu on TV. (S appears on screen).
Then press recall on remote while pressing channel up on TV..?

Bil;
If it is Eeprom problem, before you change it, try restoring it to "Factory
Default". If you don't know how, email me in the morning, and I will send
you the set-up procedure.
