1.Product Safety Servicing Guidelines
1.1 Safety precautions
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 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.
CAUTION: BEFORE SERVICING THE CHASSIS, READ THE “SAFETY
PRECAUTION” “PRODUCT SAFETY NOTICE”ON PAGE 3 OF
THIS MANUAL.
