BEFORE SERVICING THE CHASSIS, READ THE “SAFETY PRECAUTION” ON THIS
MANUAL.
WHEN REPLACEMENT PARTS ARE REQUIRED, BE SURE TO USE REPLACEMENT
PARTS SPECIFIED BY THE MANUFACTURER.
WARNING:
Service should not be attempted by anyone unfamiliar with the necessary precaution
on this receiver. The following are the necessary precautions to be observed before
servicing this chassis.
1. When replacing a chassis in the cabinet, always be certain that all the protective
devices are put back in place, such as: non-metallic control knobs, insulating covers,
shields, isolation resistor-capacitor network etc.
2. When replacing parts or circuit boards, disconnect the power cord.
3. When replacing a high wattage resistor (oxide metal film resistor) on the circuit
board, keep the resistor 10mm (1/2in) away from circuit board.
4. Connection wires must be kept away from components with high voltage or high
temperature.
5. If any fuse in this TV receiver is blown, replace it with the FUSE specified in the
chassis parts list.
1.2.Product Safety notice
Many electrical and mechanical parts in the chassis have special safety-related
characteristics.
These characteristics are often passed unnoticed by a visual inspection.
Replacement parts, which have these special safety characteristic are identified in this
manual and its supplement electrical components having such features are shaded on
the schematic diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully.
The use of substitute replacement parts, which do not have the same characteristic as
specified in the parts list may create shock, fire or other hazards.
NOTES:
Screen Image retention Do not display a still image (such as on a video game or
when hooking up a PC to this PDP) on plasma monitor panel for a long time as it can
cause screen image retention. This image retention is also known as “screen burn”.
To avoid such image retention, reduce the degree of brightness and contrast of the
screen when displaying a still image.
A still image displayed too long may cause permanent damage to the PDP Panel
Watching the PDP TV in 4:3 format or other non full screen format s for a long period of
time may leave traces of borders displayed on the left, right and centre of the screen
caused by the difference of light emission on the screen. Playing a DVD or a game
console may cause similar effect to the screen. Damages caused by the above effect

are not covered by the Warranty.
Afterimage on the Screen Displaying still images from Video games and PC for
longer than a certain period of time may produce partial afterimages. To prevent this
effect, reduce the brightness and contrast when displaying still images for a long time.
Height The PDP can normally operate only under 2000m in height. It might
abnormally function at a place over 2000m in height and do not install and operate
there.
Avoid operating the TV at temperatures below 5(41°F)
Warranty Wa rranty does not cover any damage caused by image retention; Burn-in is
not covered by the warranty.
