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.
PICTURE CAUTIONS
Picture Burn Prevention
• Continuous on-screen displays such as video games, stock market quotations, computer generated
graphics, and other fixed (non-moving) patterns can cause permanent damage to color television receivers.
Such "PATTERN BURNS" constitute misuse and are NOT COVERED by your HITACHI Factory
Warranty.
• When using Picture-in-Picture function, the sub-picture should not be left permanently in one corner of
the screen or a "PATTERN BURN" may develop over a long period of time.
