The SERVICE PERSONNEL should have the appropriate technical training knowl-
edge and experience necessary to :
Be familiar with specialized test equipment, and
Be careful to follow all safety procedures associated with high voltage CRT
circuit designs to minimize danger to themselves and their coworkers.
To avoid electrical chocks, this equipment should be used with an appropriate
power cord and be connected only to a properly grounded AC outlet
This equipment utilized a micro-gap power switch. Turn off the monitor by first
pushing the front panel power switch. Next, remove the power cord from the AC
outlet.
To prevent fire or shock hazards, do not expose this unit to rain or moisture
This symbol warns the personnel that un-insulated voltage within the unit
may have sufficient magnitude to cause electric shock.
This symbol alerts the personnel that important literature concerning the
operation and maintenance of this unit has been included.
Therefore, it should be read carefully in order to avoid any problems.

PRODUCT SAFETY CAUTION
1. When parts replacement is required for servicing, always use the manufacturer’s specified
replacement.
2. Comply with all caution and safety-related notes on the product display chassis and picture tube.
3. When replacing the component, always be certain that all the components are put back in the
place.
4. When servicing display monitor unit, it is required that the provided lead dress is used in the high
voltage circuit area.
5. It is also recommended that shatter proof goggles are worn, when removing, installing and han-
dling the picture tube. People not equipped with the proper precautionary measures mentioned
should keep the picture tube away from body while handling.
6. As for a connector, pick and extract housing with fingers properly since a disconnection and
improper contacts may occur, when wires of the connector are led.
7. Use a proper screwdriver. If you use screwdriver that does not fit, you may damage the screws.

Increases or decreases the curvature of the sides either to the left or right.
Rotates the entire display clockwise or counterclockwise.
Degauss Control: Eliminates the buildup of stray magnetic
fields that alter the correct scan of the electron beams
and affect the purity of the screen colors, focus and
convergence. When activated, your screen image will jump
and waver a bit as the screen is demagnetized.
Caution: Please allows a minimum of 20 minutes to
elapse between uses of the Degauss Control.
9300 This color setting is adjusted at the factory to the stated Kelvin
OSD: There are 3 background color (blue,black, and white). To choose background
color, press SELECT button after the selection of OSD in “Icon select window”.
Horizontal Moire Canceler: Reduces horizontal moire levels.
Vertical Moire Canceler: Reduces vertical moire levels.
EXIT: To exit the OSD window. Select EXIT in “Icon select window”, then push
SELECT button to exit OSD window.
Note: If no buttons are pushed after 10 seconds while in OSD, the window will
automactically disappear.

DISASSEMBLY
•Before you disassemble the set, turn off power and pull out the power plug.
• Use a proper screwdriver. If you user screwdriver that does not fit, you may damage the
screws.
• Disassembly is the opposite process of assembly.
• Carefully discharge the CRT anode potential by grounding to CRT dag ground harness before
removing Anode Cap.
EXPLANATION
1.Disassemble a screw like a picture.
2.Disconnect the GND wire (CRT coating earth wire) from MAIN BOARD ASSY and CRT BOARD
ASSY. This model has three kinds of CRT. Depend on CRT, the GND wire assembly is some
different. Be careful.
3.Disconnect the connector “S201”, “S202”, “S203”, Coating earth connector, and screen lead from
the CRT BOARD ASSY.
4.Disconnect the CRT BOARD ASSY from the CRT.
5.Disconnect the connector “S301”, “S601”, “S703”, “S701”, “S104” and “P102” from the MAIN
BOARD ASSY.
6.Remove the Anode Cap from the CRT.
NOTE: Carefully discharge the CRT anode by shorting it to ground before removing Anode Cap.
