Before Calling for Service
• When viewing in TEXT mode, if no TEXT broadcast is being received, the screen may become dark and blank.
Should this occur, set the Closed Caption mode to “OFF”.
• If your TV does not work normally in such case of power failure, once turn power off and then return power on
again.
Check these items and see if you can correct trouble with a slight adjustment of the controls.
