PDP TV SERVICE MANUAL 

 

 

Notice: This service manual is only read and used by

professionals. The repairman should review the part of

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. 

6   Do 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. 

7

Do not disconnect or connect the power connector by wet hands. The voltage of the product may be strong 

enough to cause an electric shock..
