SAFETY PRECAUTIONS
WARNING : TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TORAIN OR MOISTURE.
This Plasma Monitor should be set in the way indicated. If not, it may result in a fire hazard.
Take appropriate space on the top, sides and rear of the Plasma Monitor cabinet for allowing air circulation andcooling the Plasma Monitor. Minimum distance should be taken. If the Plasma Monitor is to be built into acompartment or similarly enclosed, the minimum distances mustbe maintained. Do not cover the ventilation slot on the PlasmaMonitor. Heat build-up can reduce the life of your PlasmaMonitor, and can also be dangerous.
If the Plasma Monitor is not to be used for an extended time,unplug the Plasma Monitor from the power outlet.
READ AND KEEP THIS OWNER'S MANUAL FOR LATER USE.
SIDE and TOP REAR
CAUTION IN INSTALLING
Handle the Plasma Monitor carefully when installing it and do not drop.
Locate set away from heat, excessive dust, and direct sunlight.
For correct installation and mounting it is strongly recommended to use a trained, authorized dealer. Failure tofollow correct mounting procedures could result in damage to the equipment or injury to the installer.

NOTE :When Plasma Monitor is not used for a long period of time, unlighting dots may be observed. This is caused bycharacteristic of the Plasma Monitor. If this occurs, turn the Plasma Monitor on and leave it on about 1 hour. Thesedots will gradually disappear.
Safety Instructions
Product safety should be considered when a component replacement is made in any area of the monitor.Components indicated by mark in the parts list and the schematic diagram designate components inwhich safety can be of special significance. It is, therefore, particularly recommended that the replacement ofthere parts must be made by exactly the same parts.

Setting the fixed data
(1) Receive the good quality signal.(2) Enter the Service Mode(3) Confirm fixed data to be same as data table. If it is different, change to
correct data.(4) Return to the Normal Mode
This adjustment is controlled by the CPU (IC801) thorough the IIC Data Bus Line in the chassis, and thoseadjustment data are memorized into the memory IC (IC808). Therefore, SUB CPU Board or the memoryIC (IC808) is replaced, data of those will be disappeared. Readjustment should be made. Initial data isprovided in the CPU ROM ,when memory IC (IC808) is replaced with new one, CPU ROM data is loadedinto the memory. (Data list will be shown in previous 2 pages.) Initial data is provided to operating themonitor basically. For operating the monitor quality performance, further adjustment required followingchassis electrical adjustment.
Adjustment : Enter the service mode, select item No. 69 [ Red ], 70 [ Green ] or 71 [ Blue ] (Cont AV), and
adjust a proper white balance.
Note : After adjustment, confirm white balance again by normal picture.

VideoSignal Flow
(1) CVBS, Y/CCVBS (Composite Video) or Y/C signal from AV1, AV2 or AV3 terminal is input to AV SW IC (IC1001) and
selected signal.
CVBS signal selected by IC1001 is input to 3 Dimension Y/C Separation IC (IC7101) and input to IC1001 again.
(In case of NTSC Signal) On the other hand it is input to Digital Decoder IC (IC401) and output for Monitor Out
signal (CVBS only).
(2) RGB, ComponentRGB or Component signal from AV4 terminal is output for “Through Out” terminal and input to RGB /
Component SW IC (IC1123) and selected to D-SUB RGB signal. Selected signal by IC1123 is input to IC1124.
(3) Decoder, I/P ConversionCVBS or Y/C signal from IC1001 or Component signal (480i) from IC1124 is input to Digital Decoder IC
(IC401). Component signal from IC401 is input to I/P (interlace / Progressive) Conversion IC (IC501).

Power Fail Circuit
CPU (IC801) is programmed that the set goes to standby mode when there is circuit fail as
below.1. AUDIO AMP FAIL(2) : Detected the fail of Audio AMP IC (IC071)
2. POWER FAIL (3) : Detected the voltage fail in SUB CPU Unit ( Not used in this model.)3. POWER FAIL (1) : Detected the voltage fail in SUB CPU Unit (1 point) and Main Unit (6 points).
4. OTHERS
TEMPERATURE FAIL : Detected the temperature fail ( about 80 degree) by thermal sensor IC (IC1981). CPU
communicates to FAN & Sensor Control IC (IC1821) for detection.
FAN FAIL : Detected the fan fail by the communication to FAN & Sensor Control IC (IC1821).
(The set does not go to standby mode in this fail. Display Only.)

Power Fail Circuit
When operating the Power Fail Circuit, On-Screen-Display message or LED flashing time is
shown as below.
On-Screen-Display Message1. FAN FAIL
When the cooling fan is trouble, below message is displayed. This message is displayed for 10 seconds in
every 10 minutes.
2. TEMPERATURE FAILWhen the internal temperature exceeds normal ( approximately more than 80 degrees ), below message is
displayed for 10 seconds and the Plasma monitor will be turned off automatically.
LED Flashing1. TEMPERATURE FAIL : The color of LED is ‘RED’.
2. POWER FAIL : The color of LED is ‘GREEN’.
3. SOUND AMP FAIL : The color of LED is ‘YELLOW’.
Warning!
Internal fan is trouble, not working properly.
Warning!
Internal temperature is too high.
Time of flashing Fail Name
2 Temperature
Time of flashing Fail Number
1 P FAIL 1
2 P FAIL 3
3 P FAIL 1 & 3
Time of flashing Fail Number
1 P FAIL 2
Note:1. In case of overlapped fail, 1 to 3 is repeated in turn.
2. If power fail is detected 3 times in 15 minutes, the monitor will stop operating.
3. If pull the AC cord, the information of these fails will be disappeared.
