Hi, We have a Samsung Tv 6272/7272 (TV 686WP) We are unable to access the set up to search for reception it displays locked, the child lock is off so that should not be the problem, I have also read the instructions from cover to cover and there is nothing about the set up being locked or unlocked. Any help would be appreciated. Regards: Rob.

Sorry man The only way I know to unlock it is with the original remote. They are available at http://www.remotes.com You have to press the M or Mute button and the F or the Function button at the same time. If the remote you have has these buttons try them. Like I said if it doesnt work, you will need an original remote. See if anyone you know has one you can borrow or the store where you bought the TV, maybe they will let you borrow one. Good Luck

Try unplugging the set for 4+ hours. That will cause a hard reset back to factory default settings.
