■ 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 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.

PRODUCT SAFETY NOTICE

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
be maintained. Do not cover the ventilation slot on the Plasma
Monitor. Heat build-up can reduce the life of your Plasma
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.

(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 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.

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.

■ 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 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.)
