Safety precautions 

Please read the “Points for attention for the Maintenance & Repair of PDP” and “Criterion for 

Identifying the Defects on Screen” as below, before inspecting and adjusting the TV set. 

1. “Points for attention for the Maintenance & Repair of PDP” 

To avoid possible danger, damage or jeopardy to health and to prevent PDP screen from new 

damage, the maintenance people must read the following carefully. If they ignore the following 

warnings, there will be deathful risks: 

1.1 Screens vary from one model to another and therefore not interchangeable. Be sure to use the 

same type of screen in the replacement. 

1.2 The operation voltage is approximately 350v for PDP module (including screen, driving circuit, 

logic circuit and power module). If you want to conduct maintenance work on PDP module when the 

set is in normal operation or just after the power is off, you must take proper measures to avoid 

electric shock and never have direct contact or touch with the circuitry of the working module or 

metal parts. That’s because within a short time relatively high voltage still remains on the capacitor 

of the driving part even after the power is off. Make sure to begin relevant maintenance operation at 

least one minute after the power is off. 

1.3 Don’t apply on the module any power supply that is higher than the specification. If the power 

supply used deviates from the value given in the specification, there might be a possibility of leading 

to fire or damage to the module.   

1.4 Never have operation or mounting work under unsuitable environment such as areas in the 

vicinity of water (bath room, laundry, water chute of kitchen), sources of fire, heat-radiation parts or 

direct exposure to sunlight. Otherwise there will be kickbacks. 

1.5 In case foreign substances such as water, liquid, metal slices or others fall into the module 

carelessly power must be cut off immediately. Keep the module as it is and do not move anything on 

the module. Otherwise it might be possible to contact the high voltage or cause shock short circuit 

so that it may lead to fire or electric shock. 

1.6 If there is smoke, abnormal smell or sound from the module, please cut the power off     

immediately. Likewise in case the screen doesn’t work when the power is on or during the operation, 

please also cut off the power at once. No more operation in this case.   

1.7  Do not remove or plug its connection wire when the module is in operation or right after the 

power is off. That’s because there remains a relatively high voltage on the capacitor of the driving 

circuit. If there is a need to remove or plug in the connection wire, please wait at least one minute 

after the power is off. 

1.8  Considering the module has a glass faceplate, please avoid extrusion by external force lest it 

should cause glass breakage that may get people injured. Two people are needed in cooperation to 

move this module lest contingency takes place. 

1.9 The complete TV set is designed on the basis of full consideration of thermal dissipation by 

convection, with the round hole on the top for heat emission. To avoid overheat, please do not have 

any covering on the hole during normal operation and never put it in the place where the space is
