MANUAL
Note:     This maintenance manual is intended only for the reference of the maintenance people. Please

pay attention to the following points before carrying out the maintenance work.



                                 Safety Instructions
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). Screens vary from one model to another and therefore not interchangeable. Be sure to use the
          same type of screen in the replacement.
    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.
    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.
    4). Never have operation or mounting work under unsuitable environment such as areas in the
            vicinity of water
