6 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). 6-1 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. 6-1-1 Before Making Adjustments 6-1-1 (a) ORIENTATION When servicing, always face the monitor to the east. 6-1-1 (b) MAGNETIC FIELDS Whenever possible, use magnetic field isolation equipment such as a Helmholtz field to surround the monitor. If a Helmholtz field is not available, frequently degauss the unit under test. Caution: Other electrical equipment may cause external magnetic fields which may interfere with monitor performance. Use an external degaussing coil to limit magnetic build up on the monitor. If an external degaussing coil is not available, use the internal degaussing circuit. However, do not use the internal degaussing circuit more than once per 30 minutes. 6-1-1 (c) 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. 6-1-1 (d) SIGNAL Analog, 0.714 Vp-p positive at 75 ohm, internal termination Sync: Separate/Composite (TTL level negative/positive) Sync-on-Green: Composite sync 0.286 Vp-p negative (Video 0.714 Vp-p positive) 6-1-1 (e) SCANNING FREQUENCY Horizontal: 30 kHz to 70 kHz (Automatic) Vertical: 50 Hz to 160 Hz (Automatic) Unless otherwise specified, adjust at the 1024 x 768 mode (H: 60 kHz, V: 75 Hz) signals. Refer to Table 2-1 on page 3-3. 6-1-1 (f) HIGH VOLTAGE ADJUSTMENT Signal: No signal Display image: Self raster Contrast: Maximum Brightness: Maximum Limit: 26 kV ± 0.5 kV Measure the hight voltage level at the anode cap. High voltage should be within the limit as above. If the high voltage needs adjustment use the following procedure. PROCEDURE 1. Turn the power off and disconnect the AC line cord from the power source. 2. Unsolder and remove VR501 on the Main PCB. 3. Replace VR501 and adjust the high voltage to the specification. 4. Using a soldering iron, melt the adjustment cap on VR501 to prevent any movement. 6-1-1 (g) G2 (SCREEN) VOLTAGE ADJUSTMENT Signal: No signal Display image: Self raster Contrast: Maximum Brightness: Maximum Adjust the Screen VR of the FBT so that the G2 (Screen) Voltage for SDD CRT is 430 V ± 10 V. 6-1-1 (h) HORIZONTAL FREE-RUN FREQUENCY ADJUSTMENT Signal: 60 kHz/75 Hz Contrast: Maximum Brightness: Maximum Connect the Frequency counter probe to the H-DY (Red wire). Conncet pin 26 of IC401 to the Ground. Adjust VR 402 to 58.7 kHz ± 10 Hz. 6-1-1 (I) CENTER RASTER Adjust SW401 so that the back raster comes to the center when you apply a signal of 60 kHz/75 Hz.

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 Servicing the High Voltage VR and CRT : WARNING:A high voltage VR replaced in the wrong direction may cause excessive X-ray emissions. Caution: When replacing the high voltage adjustment VR, it must be fixed by a soldering iron after it is properly set. 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. If the HV VR requires adjustment, (a) Replace the VR and adjust the high voltage to the specification. (b) Use a soldering iron to melt the adjustment cap on the HV VR to prevent any movement. 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. 4. 2. 3.

7 Troubleshooting Notes: 1. If a picture does not appear, fully rotate the brightness and contrast controls clockwise and reinspect. 2. Check the following circuits. · No raster appears: Power circuit,Horizontal output circuit, H/V control circuit, and H/V output circuit. · High voltage develops but no raster appears: Video output circuits. · High voltage does not develop: Horizontal output circuits. 7-1 No Power Does proper DC 110-366 Volts appear between the positive and negative poles of C606? Yes Does the appear 2'nd voltage of T601 (45V, 72V, 14.7V and so on)? (The condition BD602, BD603, JW71, JW63 are desoldered) Yes Does the appear 45V at D617's Cathode pin? (the condition L501's are pin is desoldered) No Does the appear 45V at D617's Cathode pin? (the condition L403's are pin is desoldered) No Does the appear 45V at D617's Cathode pin? (the condition JW71, JW63 are desoldered) No Does the appear 45V at D617's Cathode pin? (the condition CN102 is disconnected) No Check the IC102, IC101 and another components in Video Part (IC103, IC104, etc). Yes Yes Check the Q406, Q403, Q411 and those are related Horizontal control circuit. (IC401, IC402, Q404, Q401, Q402, Q405, Q408 and Q409) Yes Check the Q503, Q504 and those are related High Voltage control circuits. (IC501, Q510, Q501, Q502, Q506, D508, D517 and D524) No Check D605, C616, C618, components in primary part, the power feedback circuit (IC602, IC603, and its related circuits), D617, D618, D610, D615, D612, D620, D619, IC606 and IC607. No Check the Fuse, Bridge Diodes (D601~D604), IC601, C617 and D614. Replace the IC301. CKG7507L 7-1 7 Troubleshooting 7-2 Horizontal Line on CRT or Rainbow Color on the Screen The first of all you must check CN301. Does the ­12V appear at Pin 4 of IC301? Yes Does the pulse appear at Pin 5 of IC301? Yes Replace IC301 and check its related Vertical IC's application. Check R303 and R310. No 7 No Check the ­12V Line at power secondary part. (D615, C620) WAVEFORMS 7 2.80 V (IC401, #9) 10 Does the sawteeth wave appear at the Pin 9 of IC401? CH1 P-P = 2.80 V CH1 RMS = 3.469 V Yes No Replace IC401. 10 54.8 V (IC301, #5) CH1 P-P = 54.8 V CH1 RMS = 6.38 V 7-3 Vertical Line on CRT Does the drive pulse appear at the emitter of Q401? Yes Does the drive output pulse appear at the Collector of Q403? Yes Does the pulse appear at Gate of Q411? Yes Check Q411 and D408. No No Replace Q403 or check its related circuits. (C416 and T401) WAVEFORMS 14 15.8 V (Q411, Gate) 43 17 CH1 P-P = 15.8 V CH1 RMS = 8.37 V 17 140 V (Q403, Collector) 14 Check IC402 and its application. CH1 P-P = 140 V CH1 RMS = 52.7 V 43 7.12 V (Q401, #Emitter) CH1 P-P = 7.12 V CH1 RMS = 4.836 V 7-2 CKG7507L 7 Troubleshooting 7-4 No Raster (1) Power indicator is green WAVEFORMS 3 8.56 V (IC401, #18) Does the +B output voltage appear at the secondary side of T601? (45 V, 72 V, 14.7 V, etc) Yes 3 No Check the power supply circuits. Does the output pulse appear at Pin 18 of IC
