■ Safety Instructions SAFETY PRECAUTIONS WARNING : TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN 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 and cooling the Plasma Monitor. Minimum distance should be taken. If the Plasma Monitor is to be built into a compartment or similarly enclosed, the minimum distances must REAR SIDE and TOP be maintained. Do not cover the ventilation slot on the Plasma Monitor. Heat build-up can reduce the life of your Plasma 10 cm 6 cm Monitor, 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.
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 to follow 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 by characteristic of the Plasma Monitor. If this occurs, turn the Plasma Monitor on and leave it on about 1 hour. These dots will gradually disappear.
CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION :
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USERSERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
THIS SYMBOL INDICATES THAT DANGEROUS VOLTAGE CONSTITUTING A RISK OF ELECTRIC SHOCK IS PRESENT WITHIN THIS UNIT.
THIS SYMBOL INDICATES THAT THERE ARE IMPORTANT OPERATING AND MAINTENANCE INSTRUCTIONS IN THE OWNER'S MANUAL WITH THIS UNIT.
PRODUCT SAFETY NOTICE 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 in which safety can be of special significance. It is, therefore, particularly recommended that the replacement of there parts must be made by exactly the same parts.

■ Setting the fixed data This adjustment is controlled by the CPU (IC801) thorough the IIC Data Bus Line in the chassis, and those adjustment data are memorized into the memory IC (IC808). Therefore, SUB CPU Board or the memory IC (IC808) is replaced, data of those will be disappeared. Readjustment should be made. Initial data is provided in the CPU ROM ,when memory IC (IC808) is replaced with new one, CPU ROM data is loaded into the memory. (Data list will be shown in previous 2 pages.) Initial data is provided to operating the monitor basically. For operating the monitor quality performance, further adjustment required following chassis electrical adjustment.
(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 ■ Circuit Adjustment ● Input Signal : 1.0Vp-p / 75Ω terminated

■ Circuit Block Diagram ■ Video Signal Flow (1) CVBS, Y/C CVBS (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, Component RGB 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 Conversion CVBS 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).
(4) A/D Conversion RGB ( or Progressive Component) signal from IC1124 is input A/D Conversion IC (IC207) and converted.
(5) Panel Drive Signal from IC501 or IC207 is input to RGB Matrix IC (IC601) and proceeded for picture control. Signal from IC601 is input to Main Scaler IC (IC301) and LVDS Interface IC (IC751) and input to PDP Panel Module. IC1001 AV Switch

■ Audio Signal Flow Sound signals (L & R) from AV1, AV2 or AV3 are input to AV SW IC (IC1001) and selected. Sound signals from AV4 terminal are output for “Through Out” terminal. Sound signals from D-SUB or AV4 are input to IC1001 after selected by SW IC (IC1002) . The selected signals by IC1001 are output to Monitor Out and also input to below ICs.
Q-Sound IC (IC002) ➔ AMP IC (IC003) ➔ Audio Control IC (IC001) ➔ BBE IC (IC121) Finally signals from IC121 are input to Digital AMP IC (IC071) for speakers and AMP IC (IC031) for Head Phone. Note: Sound signals from IC001 is input Woofer AMP IC (IC004) too.

■ Power Supply Lines
■ 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 Message 1. FAN FAIL When the cooling fan is trouble, below message is displayed. This message is displayed for 10 seconds in every 10 minutes.
Warning! Internal fan is trouble, not working properly. 2. TEMPERATURE FAIL When 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.
Warning! Internal temperature is too high. LED Flashing 1. TEMPERATURE FAIL Time of flashing 2 2. POWER FAIL Time of flashing 1 2 3 3. SOUND AMP FAIL Time of flashing 1
: The color of LED is ‘RED’. Fail Name Temperature : The color of LED is ‘GREEN’. Fail Number P FAIL 1 P FAIL 3 P FAIL 1 & 3 : The color of LED is ‘YELLOW’. Fail Number 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.
