GENERAL GUIDELINES 1. It is advised to insert an isolation transformer in the
AC supply before servicing a hot chassis. 2. Always use the manufacturer's replacement safety components. The critical safety components marked with on the schematics diagrams should not be by other substitutes. Other substitute may create the electrical shock , fire or other hazards. Take attention to replace the spacers with the originals. Furthermore where a short circuit has occurred , replace those components that indicate evidence of overheating. 3. After servicing , see that all the protective devices such as insulation barriers, insulation papers, shields and isolation R-C combinations are correctly installed. 4. When the receiver is not being used for a long time of period of time , unplug the power cord of the Adaptor from the AC outlet.
There are electro-static sensitive components in PDP Module. Please earth human body when handle the PDP.In addition, please do not touch the interface connector pin with bare. 8 - Do not operate for a long time under the same pattern Operating PDP for a long time under the same pattern can cause image persistence and can damage it. Please follow following guidance. 1. Turn the power off when do not use. 2. Change the pattern periodically. LEAKAGE CURRENT COLD CHECK 1. Unplug the AC cord and connect a jumper
between the two prongs of the plug. 2. Turn the receiver's power switch. 3. Measure the resistance value with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the receiver. When the exposed metallic part a return path to the chassis the reading should be between 4Mohm and the 20Mohm. When the exposed metal does not have a return path to the chassis, the reading must be infinite.
PDP Module is very sensitive both electrically and physically.Users, therefore, are requested to follow the "Guidance of handling color PDP Module"on the followings.
1 -Be careful not to make scratch on the
LEAKAGE CURRENT HOT CHECK 1. Plug the AC cord directly in to the AC outlet. Do
not use an isolation transformer for this check.
polarizer. Surface of polarizer is soft and can be physically damaged easily.Please do not touch, push or rub polarizer surface with materials over HB hardness. 2 - Keep clean the surface. Please wear rubber glove when touch the surface of PDP screen. Please use soft and anti-static material as cleaner. 3 -Keep out of water.Water on/in the PDP may cause electrical short or corrosion. Please wipe out dry or water c
