SAFETY TIPS - 6 -
20 If the television does not operate normally by following the operating instructions, unplug this set television set
from the wall outlet and refer servicing to qualified service personnel. Adjust only those controls that are covered
in the operating instructions as improper adjustment of other controls may result in damage and will often require
extensive work by a qualified technician to restore the television set to normal operation.
21 If your television is to remain unused for a period of time, (such as when going on a holiday), turn the television
OFF and unplug it from the wall outlet.
IF THE TELEVISION DOES NOT OPERATE PROPERLY
22 If you are unable to restore normal operation by following the detailed procedure in your operating instructions,
do not attempt any further adjustment. Unplug the television and call your dealer or service technician.
23 Whenever the television is damaged or fails, or a distinct change in performance indicates a need for service,
unplug the set and have it checked by a professional service technician.
24 It is normal for some televisions to make occasional snapping or popping sounds, particularly when being
turned on or off. If the snapping or popping is continuous or frequent, unplug the set and consult your dealer or
service technician.
FOR SERVICING AND MODIFICATION
25 Do not use attachments not recommended by the television set manufacturer as they may cause hazards.
26 When replacement parts are required, be sure the service technician has used replacement parts specified by
the manufacturer that have the same characteristics as the original part. Unauthorized substitutions may result in
fire, electric shock, or other hazards.
27 Upon completion of any service or repairs to the television set, ask the service technician to perform routine
safety checks to determine that the television is in safe operating condition.
