This is not a malfunction. This happens when the cabinet slightly expands and
contracts according to change in temperature. This does not affect the TV's
performance. Do not open the rear cover of the cabinet to reconstruct the
circuits. There exists high voltage within the cabinet and it may cause electric
shock and injury. If maintenance is required, contact your dealer.
