PDP TV SERVICE MANUAL
Notice: This service manual is only read and used by
professionals. The repairman should review the part o
f
safety precaution before work.
TO PREVENT POSSIBLE DANGER,DAMAGE, AND BODILY HARM, PLEASE CONSIDER
1.Safety instruction
AND OBSERVE ALL CAUTIONS CONTAINED IN THIS PARAGRAPH.
A.Warning
If you don’t consider the following warning before maintenance, it could result in death or serious injury.
(1) The PDP module is controlled by voltage about 350V. If you need to handle the module during operation or just
after power-off, you must take proper precautions against electric shock and never touch the drive circuit
portion and metallic part of PDP module.
The capacitors in the drive circuit portion remain temporarily charged even after the power off. After turning
off the power, you must be sure to wait at least one minute before touching the module. If the remainder of
voltage is strong enough, it could result in electric shock.
(2) Do not use any other power supply voltage than the specified voltage in this product specifications. If you use
deviated power voltage from the specifications, it could result in fire hazard or product failure.
(3) Do not operate or install under the deviated surrounding from the environmental specification such as in
moisture or rain; near water-for example, bath tub, laundry tub, kitchen sink; in a wet basement; or near a
swimming pool; and also near fire or heater for example, near or over radiator heat resistor; or where it is
exposed to direct sunlight; or somewhere like that. If you use the PDP module in places above, it could result in
electric shock, fire hazard or product failure.
(4) If any foreign objects (e.g. water, liquid and metallic chip or dust) entered the PDP module, the power supply
voltage to the PDP module must be turned off immediately. Also never push objects of any kind into the PDP
module as they may touch dangerous voltage point or make short circuits that could result in fire hazard or
electric shock.
(5) If smoke, offensive smell or unusual noise should come from the PDP module, the power supply voltage to the
PDP module must be turned off immediately.
Also, when the PDP screen cannot display any picture after the power-on or during operation, the power
supply must be turned off immediately. Never continue to operate the PDP module under these conditions.
6Do not disconnect or connect the PDP module’s connector while the power supply is on, or just after power off.
Because the PDP module is operated by high voltage, and the capacitors in drive circuit remain temporarily
changed even after the power is turned off. If you need to disconnect it, you have to wait at least one minute
after power off.
7Do not disconnect or connect the power connector by wet hands. The voltage of the product may be strong
enough to cause an electric shock..

8Do not damage the power cable of the PDP module, also do not modify it.
When the power cable or connector is damaged or frayed, do not use it.
When the power connector is covered with dust, please wipe it with a dry cloth before the power on.
Caution
If you don’t consider the following cautions, it may result in personal injury or damage to the product.
Do not set the PDP module on an unstable place, vibrating place or inclined place. The PDP module may
fall or drop, and it may cause serious injury to a person, and serious damage to the product.
If you need to remove the PDP module to another place, you must turn off the power supply and detach the
interface cable and power cable from the PDP module, and watch your steps during the work. If the cable
has a damage, it may result in fire hazard or electric shock. Also if the PDP module drop or fall, it may
result in personal injury.
When you draw or insert the PDP’s cable, you must turn off the power supply and do it with holding the
connector. If you draw the cable, the electric wire in the cable could be exposed or broken. It may result in
fire hazard or electric shock.
To carry the PDP module, it be done by two workers in order to avoid unexpected accidents.
The PDP module has a glass-plate. If the PDP module is inflicted with excessive stress for example; shock,
vibration, bending and heat-shock, the glass plate could break. It may result in personal injury. And also,
do not press or strike the glass surface.
If the glass plate was broken, do not touch it with bare hand. It may result in a cut injury.
Do not place any object on the glass plate. It may scratch or break the glass plate.
Do not place any object on the PDP module. It may result in personal injury due to its fall or drop.
