■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 Sub CPU (IC801) thorough the IIC Data Bus Line in the chassis, and
those adjustment data are memorized into the memory IC (IC804). 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 (IC804) is replaced with new one, CPU ROM data is
loaded into the memory. (Data list will be shown in previous 5 pages.) Initial data is provided to operating
the monitor basically. For operating the monitor quality performance, further adjustment required following
chassis electrical adjustment.
■White Balance Adjustment
Pattern : White Pattern
Condition : Screen Size : FULL, Picture Image Level : STANDARD
Adjustment : Enter the service mode, select item No. 111 [ Red ], 112 [ Green ] or 113 [ Blue ]
(White:PC), and adjust a proper white balance.
Note : After adjustment, confirm white balance again by normal picture.

■ Power Fail Circuit
Sub CPU (IC801) is programmed that the set goes to standby mode when there is circuit fail
as below. (Refer to "Power Supply Lines: P18)
1. Power Fail 1 : Detected the low voltage fail in Main board. (From 1.5V to 5V)
2. Power Fail 2 : Detected the High voltage fail in Main board. (13V)
3. Power Fail 3 : Detected the fail of Audio AMP IC (IC101).
4. Power Fail 4 : Detected the voltage fail of Interface Board (Option).
5. Temperature Fail : Detected the fail of Temperature Sensor IC (IC1881/1891).
6. Panel Fail (ALARM) : Detected the fail of PDP Module.
Note: In case of Panel Fail (ALARM), the set does not go to standby mode. (Only "PDP_GO" line is off.)

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. 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.
LED Flashing
1. PANEL & TEMPERATURE FAIL: The color of LED is ‘RED’.
2. POWER FAIL 1& 2: The color of LED is ‘GREEN’.
3. POWER FAIL 3& 4: The color of LED is ‘YELLOW’.
Warning!
Internal temperature is too high.
Times of flashing Fail Name
1 Power Fail 1
2 Power Fail 2
3 Power Fail 1 & 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.
Note:If pull off the AC cord, the information of these fails will be disappeared.
