Servicing

Your television is fully transistorised and
does not contain any user serviceable
components.
Removal of the cabinet cover may expose you
to dangerous voltages. Refer all servicing to
qualified service personnel.
Unplug the television receiver from the wall
outlet and refer servicing to qualified service
personnel under the following conditions:
If the power cord or plug is damaged.
If liquid has been spilt into the television receiver.
If television receiver has been exposed to rain or water.
If the television receiver has been dropped or the cabinet has
been damaged.
If the television receiver exhibits a distinct change in performance.
If the television receiver does not operate normally by following the
operating instructions.
Adjust only those controls that are covered in the operating instructions
as improper adjustment of other controls may result in damage. This
will often require extensive work by a qualified technician to restore the
television receiver to normal operation.
When replacement parts are required, have the service technician
verify that the replacements he uses have the same safety
characteristics as the original parts. Use of manufacturers specified
replacements can prevent fire, shock or other hazards.

Reflections of signals from mountains or high buildings will cause
multiple images, called "Ghosts". These abnormal conditions can be
reduced to minimum by repositioning aerial or by installing new one
suited for your area.
"INTERFERENCE"
Interference may be caused by electrical appliances, car ignition
systems, etc. This should normally be a temporary condition, but
should this interference persist, contact your dealer.
