1.Product Safety Servicing Guidelines
1.1. Precautions and notices
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.

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 formats 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 Warranty does not cover any damage caused by image retention; Burn-in is not
covered by the warranty.
