4 Alignments and Adjustments This section of the service manual explains how to use the DDC JIG to adjust the black, red, green, and blue levels of the FPD when you replace the AD Board, and how to update the microprocessor when you change the Panel or Lamp(s). 4-1 Required Equipment The following equipment is necessary for adjusting the monitor: · Oscilloscope with probe tool · Computer with Windows 95 R , Windows 98 R , or Windows NT R . · DDC Control JIG 4-2 Using the DDC Control JIG After replacing the LCD Panel, Lamp(s), and / or AD Board, use the DDC Control JIG to complete your service. Attach the DDC Control JIG to the flat panel display (FPD) as shown in the diagrams, below. 4-2-1 Adjustment Procedures MONITOR INTERFACE BOARD VER. 2.0 5V DC ADAPTOR PARALLEL CABLE PC SIGNAL GENERATOR SIGNAL CABLE Use the following procedures whenever you replace the AD Board, Panel, or one or both of the Lamps. 4-2-1 (a) When Replacing the AD Board 1. Remove the old AD Board and replace it with a new board. 2. Perform the procedures described in section 4-2-3 (b). 3. Perform other procedures using the DDC Control JIG, if necessary. 4-2-1 (b) Color Auto Adjustment 1. After displaying 16-Gray pattern press "+", "­", and "source" buttons. 2. During normal execution of Auto Algorithm the screen image may change. If Auto Algorithm does not excute properly, try one more. 3. After normal execution of Auto Algorithm, confirm optimal settings by observing the contrast of several different patterns on the display. 4-2-3 (c) White Balance Adjustment 1. After displaying white pattern (on the WUXAG mode), press "+","­", and "PIP" buttons. 2. During normal execution df white balance the screen, image may change. 3-WIRE CABLE Figure 4-1.

1 Precautions Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as electrical shock. 1-1 Safety Precautions 1-1-1 Warnings 1. 2. For continued safety, do not attempt to modify the circuit board. Disconnect the AC power and DC Power Jack before servicing. DEVICE UNDER TEST TEST ALL EXPOSED METAL SURFACES (READING SHOULD NOT BE ABOVE 0.5mA) 1-1-2 Servicing the LCD Monitor 1. 2. When servicing the LCD Monitor Disconnect the AC line cord from the AC outlet. It is essential that service technicians have an accurate voltage meter available at all times. Check the calibration of this meter periodically. LEAKAGE CURRENT TESTER 2-WIRE CORD 1-1-3 Fire and Shock Hazard Before returning the monitor to the user, perform the following safety checks: 1. Inspect each lead dress to make certain that the leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the monitor. Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacitor networks, mechanical insulators, etc. Leakage Current Hot Check (Figure 1-1): WARNING: Do not use an isolation transformer during this test. Use a leakage current tester or a metering system that complies with American National Standards Institute (ANSI C101.1, Leakage Current for Appliances), and Underwriters Laboratories (UL Publication UL1410, 59.7). 4. ALSO TEST WITH PLUG REVERSED (USING AC ADAPTER PLUG AS REQUIRED) EARTH GROUND Figure 1-1. Leakage Current Test Circuit With the unit completely reassembled, plug the AC line cord directly into a 120V AC outlet. With the unit's AC switch first in the ON position and then OFF, measure the current between a known earth ground (metal water pipe, conduit, etc.) and all exposed metal parts, including: metal cabinets, screwheads and control shafts. The current measured should not exceed 0.5 milliamp. Reverse the power-plug prongs in the AC outlet and repeat the test. 2. 3. 1-1-4 Product Safety Notices Some electrical and mechanical parts have special safety-related characteristics which are often not evident from visual inspection. The protection they give may not be obtained by replacing them with components rated for higher voltage, wattage, etc. Parts that have special safety characteristics are identified by ! on schematics and parts lists. A substitute replacement that does not have the same safety characteristics as the recommended replacement part might create shock, fire and / or other hazards. Product safety is under review continuously and new instructions are issued whenever appropriate.

Before servicing units covered by this service manual, read and follow the Safety Precautions secti
