The repairman should review the part of safety precaution before work. 1.Safety instruction TO PREVENT POSSIBLE DANGER,DAMAGE, AND BODILY HARM, PLEASE CONSIDER 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 circuit
