Product Safety Servicing Guidelines
CAUTION: BEFORE SERVICING THE CHASSIS, READ THE "SAFETY
PRECAUTION" "PRODUCT SAFETY NOTICE"ON PAGE 3 OF
THIS MANUAL.
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.
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.
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.

33
PDP TV Service Manual
1. Do NOT attempt to install the TV by yourself to avoid mistakes or hazard. Refer all installation to
qualified servicing personnel.
2. Do NOT install the TV on a wall aslope or a wall that makes the TV screen sloping over 25°off plumb
line. Otherwise, it may cause tumble or injury.
3. Refer all installation to qualified servicing personnel.
4. One must follow the instructions in this guide to correctly install the TV.
5. It requires more than one person to install the TV.
6. Before installation, examine whether the wall conforms to the specifications and whether the supplied
parts can be fixed on it. The wall for mounting should sustain the weight of TV and speakers, e.g.
cement wall or brick wall. Do NOT attempt to install the TV on a flexible wall such as sand wall or
plaster wall, unless the bolt are fixed on an area with standard building rigidity which sustains the
weight of the TV and speakers. If the rigidity of the wall can not be measured, every mounting hole
should sustain a frontal force of over 100N and a shearing force of over 200N.
7. Use the specified electric drill and drill bit for drilling. The drilling holes should conform to the
specifications.
8. To avoid fire and shock, do NOT place radiator, heater or humidifier below the installed TV.
9. The TV should be kept away from moisture, sensors and power line. The TV should be kept away
from impact and vibration.
10. Ensure that the power supply be disconnected before installation for fear of fire and shock.
11. The max adjusting degree is 5°
Wall-mounting Installation Steps:
1. Take out the brackets from the package, and check if there are serious defects (e.g. infirm juncture).
2. Adjust the bracket to the desired angle. Use the bolts 2 to adjust the angle by meeting holes of column
beam 8 and holes of lever 5
3. Drill locating holes in the specified dimension in a vertical wall of concrete or brick. The hole size
should be 11mm. The hole depth should accommodate the expanding tube of the bolt.
4. Fix the bolts into the drilled holes in step3, and then cover each bolt with a metal washer. Meet the
four mounting holes in the bracket with the four bolts in the wall, cover each bolt with a metal washer,
and then fasten with a screw nut. Check its rigidity by pulling the bracket.
5. Take away the handles and the base from the back of TV;
6. Fix the fixture disk 4 to the back cover of the TV using four bolt 3(M8X45) .
7. Wall-mount the TV by putting the four fixture disks into the four mounting holes A.
8. If the customer is not satisfied with the mounting angle, take down the TV and adjust the angle before
re-mounting.
9. After wall-mounting the TV, use bolts 2 to fix the fixture disks for fear of accidental slide.
