To check the digital channel signal strength, see "Checking the digital signal strength" on page 31. • Enter 9999 to access parental controls, then set a new password. See "Setting or changing the password" on page 32. • If a setting is grayed, the setting is not available in the current video input mode. • When the TV is in use, the temperature rises naturally and may cause the cabinet to expand or contract which can cause a creaking noise. This is not a malfunction. • Make sure that the Button Lock option is set to Off. See "Locking control buttons" on page 32. • Unplug the power cord, wait a few seconds, then plug the cord back in and turn on your TV. • Make sure that the sleep timer is not turned on.
