4 Alignment and Adjustments This section of the service manual explains how to make permanent adjustments to the monitor. Directions are given for adjustments using the monitor Interface Board Ver. 2.0 and software (Softjig). 4-1 Adjustment Conditions Caution: Changes made without the Softjig are saved only to the user mode settings. As such, the settings are not permanently stored and may be inadvertently deleted by the user. 4-1-1 Before Making Adjustments 4-1-1 (a) ORIENTATION When servicing, always face the monitor to the east. 4-1-1 (b) WARM-UP TIME The monitor must be on for 30 minutes before starting alignment. Warm-up time is especially critical in color temperature and white balance adjustments. 4-1-1 (c) SIGNAL Analog, 0.7 Vp-p positive at 75 ohm, internal termination Sync: Separate (TTL level negative/positive) 4-1-1 (d) SCANNING FREQUENCY Horizontal : 30 kHz to 54 kHz (15" Automatic) Horizontal : 30 kHz to 70 kHz (17" 70kHz Automatic) Horizontal : 30 kHz to 85 kHz (17" 85kHz Automatic) Vertical : 50 Hz to 120 Hz (15" Automatic) Vertical : 50 Hz to 160 Hz (17" Automatic) Unless otherwise specified, adjust at the 800 x 600 mode (15" 54 kHz/85 Hz), 1024 x 768 mode (17" 68 kHz/85 Hz), Refer to Table 2-1 on page 2-3. 4-1-2 Required Equipment The following equipment may be necessary for adjustment procedures: 4-1-2 (a) DISPLAY CONTROL ADJUSTMENT 1. Non-metallic (­) screwdriver: 1.5, 2.5, 3 mm 2. Non-metallic (+) screwdriver: 1.5, 2.5, 3 mm 3. Digital Multimeter (DMM), or Digital Voltmeter 4. Signal generator, or DM200 software 5. Personal computer 4-1-2 (b) COLOR ADJUSTMENTS 1. All equipment listed in 4-1-2 (a), above 2. Color analyzer, or any luminance measurement equipment. 4-1-3 After Making Adjustments After finishing all adjustments, test the monitor in all directions. If, for example, the monitor does not meet adjustment specifications when facing north, reposition the monitor to face east and readjust. This time, try for an adjustment closer to the ideal setting within the tolerance range. Test the unit again in all directions. If the monitor again fails to meet specifications in every direction, contact your Regional After Service Center for possible CRT replacement.

1 Precautions 1-1 Safety Precautions WARNINGS 1. For continued safety, do not attempt to modify the circuit board. 2. 3. Disconnect the AC power before servicing. When the chassis is operating, semiconductor heatsinks are potential shock hazards. 3. 2. 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). 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. (READING SHOULD NOT BE ABOVE 0.5mA) 1-1-1 1. Servicing the High Voltage circuit and CRT : When servicing the high voltage circuit, remove the static charge by connecting a 10 kohm resistor in series with an insulated wire (such as a test probe) between the chassis and the anode lead. When troubleshooting a monitor with excessively HV, avoid being unnecessarily close to the monitor. Do not operate the monitor for longer than is necessary to locate the cause of excessive voltage. High voltage should always be kept at the rated value, no higher. Only when high voltage is excessive are X-rays capable of penetrating the shell of the CRT, including the lead in glass material. Operation at high voltages may also cause failure of the CRT or high voltage circuitry. When the HV regulator is operating properly, there is no possibility of an X-ray problem. Make sure the HV does not exceed its specified value and that it is regulating correctly. The CRT is especially designed to prohibit X-ray emissions. To ensure continued X-ray protection, replace the CRT only with one that is the same or equivalent type as the original. Handle the CRT only when wearing shatterproof goggles and after completely discharging the high voltage anode. Do not lift the CRT by the neck. 2. 4. 3. 4. 5. DEVICE UNDER TEST TEST ALL EXPOSED METAL SURFACES LEAKAGE CURRENT TESTER 2-WIRE CORD 6. ALSO TEST WITH PLUG REVERSED (USING AC ADAPTER PLUG AS REQUIRED) 7. EARTH GROUND 1-1-2 Fire and Shock Hazard : Figure 1-1. Leakage Current Test Circuit 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
