IF THIS 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 if there is a distinct change in performance that
indicates a need for service, unplug the television and have it checked by a qualified 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 manufacturer as they may cause hazards.
26 If 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, 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 projection 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.
Public Viewing of Copyrighted Material
Public viewing of programs broadcast by TV stations and cable companies, as well as programs from other
sources, may require prior authorization from the broadcaster or owner of the video program material.
