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, Audio Board or the memory IC(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.

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 Audio Unit (3 points)
3. POWER FAIL (1) : Detected the voltage fail in Audio 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.
