while it is On or in standby mode. If patch appears in your TV set try the following
before calling your service centre or dealer. Place the TV set in desired position and
switch it Off by the main power switch. Allow the set tocool down for at least 30

remove the patch automatically. Please call service only in case this operation does
not help.
