Precautions
1. Precautions
Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as electrical shock and Xray exposure.
1-1 Safety Precautions
1-1-1 Warnings
1. For continued safety, do not attempt to modify the circuit board. 2. Disconnect the AC power before servicing. 3. With AC power applied, semiconductor heat sinks are potential shock hazards.
1-1-2 Servicing the High Voltage System and CRT
1. When servicing the high voltage system, 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. (Disconnect the AC line cord from the AC outlet.) 2. Do not lift the CRT by the neck. 3. Handle the CRT only while wearing shatterproof goggles and after completely discharging the high voltage anode.
1-1-3 X-Rays and High Voltage Limits
1. Keep the high voltage below the specified maximum level. Be sure all service personnel are aware of the procedures and instructions covering Xrays. The only potential source of Xray in current solid state display monitors is the CRT. However, the CRT does not emit measurable Xray radiation if the high voltage is as specified in the fire and shock hazard instruction. Only when high voltage is excessive are Xrays capable of penetrating the shell of the CRT, including the lead in glass material. 2. It is essential that service technicians have an accurate high voltage meter available at all times. Check the calibration of this meter periodically. 3. High voltage should always be kept at the rated value, no higher. Operation at high voltage may cause failure of the CRT or high voltage circuitry and, under certain conditions, may produce Xrays in excess of acceptable levels.

Service Manual
Precautions
4. When the high voltage regulator is operating properly, there is no possibility of an Xray problem. Test the brightness and use a meter to monitor the high voltage each time a color monitor is serviced. Make sure the high voltage does not exceed its specified value and that it is regulating correctly. 5. The CRT is especially designed to prohibit Xray emissions. To ensure continued Xray protection, replace the CRT only with one of the same type or an equivalent of the original. Carefully reinstall the CRT shields and mounting hardware; these also provide Xray protection. 6. When troubleshooting a monitor with excessively high voltage, avoid being unnecessarily close to the monitor. Do not operate the monitor for longer than is necessary to locate the cause of excessive voltage. PRECAUTIONS
1-1-4 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 inside the monitor.

Precautions
2. Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor capacitor network mechanical insulators, etc. 3. To be sure that no shock hazard exists, check for leakage current in the following manner. a. Plug the AC line cord directly into a 120 Volt AC outlet.(Do not use an isolation transformer for this test) b. Using two clip leads, connect a 1.5k ohm, 10 watt resistor paralleled by a 0.15 F capacitor in series with an exposed metal cabinet part and a known earth ground, such as an electrical conduit or electrical ground connected to an earth ground. c. Use a SSVM or VOM with 1000 ohms per volt or higher sensitivity to measure the AC voltage drop across the resistor (see Figure 1 1). d. Connect the resistor to an exposed metal part having a return path to the chassis(metal cabinet, screw heads, knobs, shafts, escutcheon, etc.) and measure the AC voltage drop across the resistor. e. Any reading of 5.25 Volt RMS(this corresponds to 3.5 milliampere AC) or more is excessive and indicates a potential shock hazard. Correct the shock hazard before returning the monitor to the user.
1-1-5 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. A substitute replacement that does not have the same safety characteristics as the recommended replacement part may create shock, fire and / or other hazards. Product safety is under review continuously and new instructions are issued whenever appropriate.

Precautions
1-2 Servicing Precautions
WARNING : An electrolytic capacitor installed with the wrong polarity might explode. Caution : Before servicing instruments covered by this service manual and its supplements, read and follow the Safety Precautions section of this manual. If unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions, always follow the safety precautions. PRECAUTIONS
Note :
1-2-1. General Servicing Precautions
1. Servicing precautions are printed on the cabinet, and should be followed closely. 2. Always unplug the unit's AC power cord from the AC power source before attempting to : (a) remove or reinstall any component or assembly, (b) disconnect PCB plugs or connectors, (c) connect a test component in paralled with an electrolytic capacitor. 3. Some components are raised above the printed circuit board for safety. An insulation tube or tape is sometimes used. The internal wiring is sometimes clamped to prevent contact with thermally hot components. Reinstall all such elements to their original position. 4. After servicing, always check that the screws, components and wirings have been correctly reinstalled. Make sure that the portion around the serviced part has not been damaged. 5. Check the insulation between the blades of the AC plug and accessible conductive parts(examples: metal panels, input terminals and earphone jacks). 6. Insulation Checking Procedure : Disconnect the power cord from the AC source and turn the power switch ON. Connect an insulation resistance meter(500 V) to the blades of the AC plug. The insulation resistance between each blade of the AC plug and accessible conductive parts(see above) should be greater than 1 megohm. 7. Never defeat any of the B voltage interlocks. Do not apply AC power to the unit (or any of its assemblies) unless all solid state heat sinks are correctly installed. 8. Always connect a test instrument's ground lead to the instrument chassis ground before connecting the positive lead; always remove the instrument's ground lead last.

Precautions
1-3 Electrostatically Sensitive Devices(ESD) Precautions
Some semiconductor (solid state) devices can be easily damaged by static electricity. Such components are commonly called Electrostatically Sensitive Devices(ESD). Examples of typical ESD devices are integrated circuits and some field effect transistors. The following techniques will reduce the incidence of component damage caused by static electricity. 1. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your body by touching a known earth ground. Alternatively, wear a discharging wrist strap device. To avoid a shock hazard, be sure to remove the wrist strap before applying power to the monitor. 2. After removing an ESD equipped assembly, place it on a conductive surface such as aluminum foil to prevent accumulation of an electrostatic charge. 3. Do not use freon propelled chemicals. These can generate electrical charges sufficient to damage ESDs. 4. Use only a grounded tip soldering iron to solder ESDs. 5. Use only an anti static solder removal device. Some solder removal devices not classified as "anti static" can generate electrical charges sufficient to damage ESDs. 6. Do not remove a replacement ESD from its protecitive package until you are ready to install it. Most replacement ESDs are packaged with leads that are electrically shorted together by conductive foam, aluminum foil or other conductive materials. 7. Immediately before removing the protective material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed. Caution : Be sure no power is applied to the chassis or circuit and observe all other safety precautions. 8. Minimize body motions when handling unpackaged replacement ESDs. Motions such as brushing clothes together, or lifting your foot from a carpeted floor can generate enough static electricity to damage an ESD.

5-5-1 Static (Center) Convergence
Static convergence involves the alignment of the red, blue and green lines in the center area of the display. See "Dynamic Convergence" for alignment of the color fields around the edges of the display. CONDITIONS Orientation : Monitor facing east Warm up : 30 minutes Display image : Crosshatch Pattern As shown in Figure 5 6, the CRT used in these monitors has the same magnet cofiguration.
Use the following steps to correct any static misconvergence: 1. locate the pair of 4 pole magnet rings. 2. Unlock the rings and rotate the individual rings (change the space between tabs) to converge the vertical red and blue lines. 3. Rotate the pair of rings (maintaining the space between tabs) to converge the horizontal red and blue lines. 4. After completing the red and blue center convergence adjustment, locate the pair of 6 pole magnet rings.

Alignment and Adjustment
5. Rotate the individual rings (change the space between tabs) to converge the vertical red and blue (magenta) and green lines. 6. Rotate the pair of rings (maintaining the space between tabs) to converge the horizontal red and blue (magenta) and green lines. Don't rotate the 2 pole magnets, as they adjust for color purity. 7. Mark the correct position for the magnets and apply a small line of glue to hold the magnets in place. Lock the rings in place.
ALIGNMENT AND ADJUSTMENT
5-5-2 Dynamic (Edge) Convergence
Use the following procedure to correct minor dynamic (edge) misconvergence. If, after using this procedure, dynamic misconvergence is still greater than the tolerance around the periphery of the display area, contact the Regional After Service Center for possible CRT replacement. 1. Make sure the display is not affected by external magnetic fields. 2. Make sure the static convergence is properly adjusted. 3. Strategically place small magnetic strips on the back of the CRT to correct the misconvergence. Be careful not to remove the paper protecting the adhesive on the magnetic strip until you are satisfied with their placement and the dynamic convergence. 4. When you are satisfied with the convergence around the edge of the CRT, glue the magnets to the back of the CRT permanently.
