This product contains special designed circuits and components that were designed for safety purposes. For continued protection, changes should not be made to the original design unless authorized in writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Service should be performed by qualified personnel only. 2. Alterations to the design or circuitry of this receiver should not be made. Any design alterations or additions will void the manufactuer's warranty and will further relieve the manufacturer of responsibility for personal injury or property damage resulting therefrom. 3. Many electrical and mechanical parts in MONITOR sets have special safety-related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in the parts list of this service manual. Electrical components having such features are identified by shading on the schematics and by (*) on the parts list in this service manual. The use of a substitute replacement which does not have the same safety characteristics as the recommended replacement part shown in the parts list may create shock, fire, or other hazards. 4. If any repair has been made to the chassis, it is recommended the the B1 setting be checked or adjusted (See ADJUSTMENT OF B1 VOLTAGE). 5. The high voltage applied to the picture tube must conform with that specified in this service manual. Excessive high voltage can cause an increase in X-Ray emission, arcing and possible component damage, therefore operation under excessive high voltage conditions should be kept to a minimum, or should be prevented. If severe arcing occurs, remove the AC power immediately and determine the cause by visual inspection (incorrect installation, cracked or melted high voltage harness, poor soldering, etc.). To maintain the proper minimum level of soft X-Ray emission, components in the high voltage circuitry including the picture tube, must be the exact replacements or alternatives approved by the manufacturer of the complete product. 6. Do not check high voltage by drawing an arc. Use a high voltage meter or a high voltage probe with a VTVM. Discharge the picture tube before attempting meter connection by connecting a clip lead to the ground frame and connecting the other end of the lead through a 1OkO 2W resistor to the anode button. 7. When service is required, observe the original lead dress. Extra precaution should be given to assure correct lead dress in the high voltage circuit area. Where a short circuit has occurred, those components that indicate evidence of overheating should be replaced. Always use the manufacturer's replacement components. 2 SAFETY PRECAUTIONS (Continued) 8. ISOLATION CHECK (SAFETY FOR ELECTRICAL SHOCK HAZARD) After re-assembling the product, always perfrom an isolation check on the exposed metal parts of the cabinet, screwheads, cable jacks, controls shafts, etc., to be sure the product is safe to operate without danger of electrical shock. (A) DIELECTRIC STRENGTH TEST The isolation between the AC primary circuit and all metal parts exposed to the user, particularly any exposed metal part having a return path to the chassis should withstand a voltage of 1, 100V AC (r.m.s.) for a period of one second. This method of test requires test equipment not generally found in the service trade. * (8) LEAKAGE CURRENT CHECK Plug the AC line cord directly into the AC outlet (do not use a line isolation transformer during this check). Using a "Leakage Current Tester", measure the leakage current from each exposed metal part of the cabinet, particularly any exposed metal part having a return path to the chassis, to a known good earth ground (water pipe, etc.). Any leakage current must not exceed 0.5mA. * ALTERNATE CHECK METHOD Plug the AC line cord directly into the AC output (do not use a line isolation transformer during this check). Use an AC voltmeter having 1,000 ohms per volt or more sensitivity in the following manner. Connect a 15000 10W resistor paralleled by a 0.15JLF AC-type capacitor between an exposed metal part and a known good earth ground (water pipe, etc.). Measure the AC voltage across the resistor with the AC voltmeter. Move the resistor connection to each exposed metal part, particularly any exposed metal part having a return path to the chassis, and measure the AC voltage across the resistor. Now, reverse the plug in the AC outlet and repeat each measurement. Any voltage measured must not exceed 0.35V AC (r.m.s). This corresponds to O.5mA AC (r.m.s.). CAUTION: When troubleshooting, with power applied, use an isolation transformer and confirm that the CRT earth wire is connected to the CRT socket board and the chassis. 3 ADJUSTMENTS - PURITY, CONVERGENCE AND WHITE BALANCE PICTURE TUBE The picture tube is a precision in-line gun type. For this picture tube, dynamic convergence is carried out by a precision deflection yoke which eliminates the use of a convergence yoke and a convergence circuit. The adjustment of the picture tube is therefore made easier as only the adjustment of static convergence by using a magnet is enough. The deflection yoke and purity/convergency magnets assembly has been set at the factory and requires no field adjustments. However, should the assembly be accidentally jarred or tampered vyith, some or all adjustment may be necessary. YOKE LOCKING RING PURITY COLOR PURITY & VERTICAL CENTER Loosen yoke retaining clamp (Fig. 2-1). With a sharp knife, cut between the picture tube and the wedge. Remove wedges completely and clean off dried adhesive from the picture tube. PAINT is used to lock the tabs of the purity/ convergence magnet assembly in place (Fig. 2-1). The paint must be removed with the end of a screwdriver before any adjustments are attempted. 1. Inject a Video Signal (RASTER) to the Video input terminal. 2. Let the purity tabs come in line horizontally as is shown in Fig. 2-3. A long tab should be in the same direction as the other short tab. 3. Move the yoke slowly backward. 4. Tum the green cut-off control to maximum and the red and blue cut-off controls to minimum. Then adjust the screen control so that the green band can be seen best. (Fig. 2-4) 5 . Rotate the two tabs in the opposite direction with them kept at an angle. Move them in either direction so that the green band is centered on the picture tube. 6 . Check the vertical center position by displaying a horizontal line. If incorrect, bring it to the center by rotating the two tabs, kept at an angle, together in either direction. (Fig. 2-5, 2-6) 7. Repeat steps 5 and 6 alternately until the green band and the vertical centre are in line. a. Move the yoke slowly towards the bell of the tube so that the whole surface of the picture tube is filled with a pure green raster. 9. Turning the red cut-off control to maximum and the green cut-off control to minimum, check for pure red raster. 10. Turning the blue cut-off control to maximum and the green cut-off control to minimum, check for pure blue raster. 11. Secure yoke retaining clamp (do not install wedges at this time).

Fig. 2-6 4 (FRONT VIEW) (FRONT VIEW) l) GREEN \ AROUND~ CENTRE ~ MAGENTA STATIC CONVERGENCE & DYNAMIC CONVERGENCE Static convergence is achieved by four magnets located on the neck, nearest the base of the picture tube. The front pair of magnetic rings (closest to the purity tabs) are adjusted to converge the red and blue crosshatch lines. The rear pair of convergence rings (closest to the base of the picture tube) are adjusted to converge the magenta (Red/Blue) and green crosshatch lines. Dynamic convergence is achieved by tilting the deflection yoke, Up-Down and Left-Right. 1. Inject Video Signal (CROSSHATCH) to the Video input terminal and adjust BRIGHTNESS and CONTRAST control for distinct pattern. 2. Adjust the convergence around the edges of the picture tube tilting the yoke, up-down and left-right. Temporarily install one wedge at the top of the yoke. (Fig. 2-9, 2-10, 2-11) 3. Rotate the front pair of tabs as a unit to minimize the separation of the red and blue lines around the center of the screen. To adjust the convergence of red and blue, vary the angle between the tabs. 4. Rotate the rear pair of tabs as a unit to minimize the separation of the magenta and green lines. (Fig. 2-8) 5. Adjust the spacing of the rear tabs to converge the magenta and green lines. 6. Apply paint to fix 6 magnets. 7. Remove the wedge installed temporarily on the yoke. 8. Tilting the angle of the yoke up, down and sideways, adjust the yoke so as to obtain the circumference convergence. (Fig. 2-10, 2-11) 9. Insert three wedges to the positions as shown in Fig. 2-12 to obtain the best circumference convergence. 10. Secure wedges in position with the adhesive backing provided or use a non-conductive silicon/rubber compound. 11. White balance adjustment (Black & White tracking) can now be performed. r RED AROUND CENTRE .' . ' BLUE , Fig. 2-7 Fig. 2-8 (REAR VIEW) (l)WEDGE DEF.

Inject a Video Signal (RASTER) to the Video input terminal. 2. Set the red and green drive controls for their mechanical center. 3. Turn the red, green and blue cut off controls and the screen control fully counterclockwise. 4. Change the service switch as shown in Fig. 2-6, to the "S" position. 5. Turn screen control slowly clockwise until a very faint horizontal line appears. 6. Turn the cut off control of the color which has appeared first, clockwise by about 10° and then adjust the screen control again so that the color may shine faintly. 7. Turn the other color cut off controls slowly clockwise until a reasonable white line appears. 8. Return the service switch to normal (N) position. (Fig. 2-6) 9. Adjust the red and green drive controls for best white highlights. Tilting the yoke upward will move the lines as shown with the arrows.

Inject a video signal 1701 (110V) Regulate VR, R109, for B1 adjustment so that Dc voltage between TP-91 and earth is 110 volts. 1702 (125V.) Confirm that the voltage at TP-94 and IC901 pin 4 is 125 volts. NOTE: Meter should be periodically calibrated at 20K ohms/volt. FOCUS Adjust the FOCUS control for best overall definition and picture detail at normal brightness and contrast. VERTICAL POSITION Adjust the V. center VR R428 (R429) to the optimum vertical picture position. VERTICAL HEIGHT AND LINEARITY 1. 2. 3. 4. Display a pattern which allows easy confirmation of symmetry (such as a circle or crosshatch). Reduce the vertical size with the V. HEIGHT VR. Adjust the vertical linearity with the V. LIN. VR. Readjust the vertical height, so that the picture extends to normal size. HORIZONTAL WIDTH Adjust H. WIDTH control coil L503 (L522) by turning it with a hexagonal adjusting bar only if RIGHT and LEFT sides of picture can't be seen. HORIZONTAL OSCILLATOR 1. 2. 3. 4. 5. Set the H. FREQ. VR to the mechanical center position. Connect a jumper clip between TP-33A and TP-33B. While rotating the H. FREQ. VR, R504, keep the picture stationary or slowly moving. Remove the jumper wire. Make sure that the set maintains horizontal sync, when signals are switched. 6 SUB TINT AND SUB COLOR 1. 2. Display a picture and set the tint and color VRs on the control panel to the central click position. Adjust the sub tint VR, R305 and sub color VR, R303 for the optimum display. SUB CONTRAST AND SUB BRIGHT 1. 2. Display a picture and set the contrast and bright VRs on the control panel to the center click positions. Adjust the sub contrast VR, R209 and sub bright VR, R22 (R863) for optimum display. COLOR SYNC 1. 2. 3. 4. 5. 6. Display a color video signal. Connect jumper clips between TP-40 and earth (TP-E) and between TP-51 and IC301 pin 15 (TP-51 B). Use a non-metallic screwdriver to turn trimmer capacitor C308. Adjust so that the rolling color stripes become thick and the rolling slows or stops. Remove jumper clips. Confirm that color sync is not disrupted when signals are switched. 3.58 MHz TRAP 1. 2. 3. Receive a Video Signal into the Video input terminal. Connect oscilloscope probe to DL201 (Delay Line) output side. Turn the core of T201 so that that 3.58MHz signal is minimized.

Refer to the 1702 schematic for differences In component values and Identification. 50HZ 160HZ 16 TROUBLESHOOTING GUIDE No raster, no sound (B1 is normal) NOTE: 1702 locations in ( ). [Cause] Horizontal deflection circuit Problems in the horizontal deflection circuit hinder generation of high focusing voltage, BH 160V and B2 12V, resulting in no raster, no sound. 1. As long as normal BH 160V is generated, the horizontal output circuit properly operates, producing pulses during the flyback period of the saw-tooth wave current passing through the horizontal deflection coil. If a problem is found with normal BH voltage, the problem area should be the secondary coil of the flyback transformer. 2. When the AC voltage between base and emitter of the horizontal output transistor X01 (0522) is about O.SV, it is supplied with input pulses. The problem is therefore in the horizontal output circuit. When, however, X01 (0522) is shorted, this AC voltage is not indicated even if there are input pulses at X01 (0522). 3. AC voltage is measured between the collector and ground of X501 (0521) horizontal drive as shown. When the specified voltage is shown on the meter, the horizontal output circuit is the problem; while, when there is no voltage indication, the trouble is in some element(s) preceding X501 (0521). Check if those transistors and les are damaged using a voltage measurement. C START t Vc. VB at X701 (0501) X-Ray protector • ABNORMAL Check X701 (0501) I + NORMAL Is normal BH 160V generated?

The regulator PCB assembly used in 1702 models differs from the 1701 power PCB assembly. The B1 voltage circuits should be checked beginning with IC901. [Cause] Abnormal B1 voltage indicates trouble in the power supply circuit. When B1 voltage is not only low but also abnormally high, X701 (Q501) of the X-ray protector is turned on, setting the collector voltage to 0 V. The horizontal oscillator is then disabled resulting in no raster and no sound. 1. When D 105, R105, R108, R109 are open, the base voltage of X 101 and X 102 rise to increase B1 voltage to more than 130V. This causes the X-ray protector to work, resulting in no raster. 2. If the base voltage drops as when R103 is open or C105 is shorted, the B1 voltage is reduced to less than 40 V. This will mostly result in no raster, no sound. 3. When the B1 voltage drops to about 70 V, because R91 0 is open and D1 05 is shorted, the screen becomes dark and the raster size is reduced because of insufficient horizontal and vertical amplitude.

[Cause] Malfunction of the video amplifier IC201, X202 (lC201, 0201) The video signal and the audio signal output are supplied respectively to the video amplifier IC20 1 and the audio circuit IC601 . Sound is had but no picture; therefore, the faulty part is IC201 and its external elements. Since pin 16 of the IC201 to the cathode of CRT is connected by a DC-coupled amplifier, a fault raising the emitter voltage of X202 (0201) will cause the three initial ouptut transistors to cut off, resulting in no raster. Check also the screen grid circuit for igniting the CRT heater and the high voltage module. No sound (with normal picture) NOTE: 1701 - Flowchart 1702 - Audio circuit has been reduced to IC601. [Cause] Trouble in the audio circuit IC601, X601, X603 or X604 are faulty. How is collector voltage of X602?

If this is broken, the trouble is due to short of X401 or break of 0401 . 1702 - Circuits in 1702 monitor differ but the operation remains the same. Check vertical controls/deflection circuits. [Cause] Malfunction of the vertical deflection circuit. When the vertical deflection circuit is faulty, saw-tooth current is not applied to the vertical deflection coil, resulting in a single horizontal line. During troubleshooting, reduce brightness contrast to prevent an ion spot on the CRT. 1. R401 broken, C403, 0402, C413 short: 82 12V is not supplied, disabling IC501. 2. R411, R412 broken, C407 short: the voltage at IC501 pin 3 is set to zero disabling the V-amplifier and the voltage at pin 2 is set to zero to turn off X402. 3. R414, R415 are broken: VB of X401 is zero disabling X401 and X402. 4. Also check if C402 is short or open. 5. Too high VB of X402 is because of C401 short or failure in IC501 or X402. Note: When the voltage generator fails to supply 82 12V to the secondary coil of the flyback transformer of the horizontal output circuit due to malfunction, a single horizontal line and no sound will result. ( START ) I ;- VB at the vertical output transistor X402 is nearly zero Vc. VB. VE of X401 and Vc of X402 are very high (more than 100 V) R401, R411, R412 or R413 broken.

About 25 irregular lines appear on the upper half of the screen. R408 and R409 faulty Vertical amplitude small (about 15 cm) R410 faulty Vertical amplitude small (about 2 cm). Picture goes slightly up and down and flickers. Picture appears only on the lower half of the screen R416 faulty C409 open Vertical flyback line appears. R419 faulty Small number of irregular lines 21 Improper horizontal or vertical synchronization NOTE: 1701 and 1702 locations are the same. [Cause] 1) Defective horizontal and vertical sync: The sync separator and amplifier consists of an IC(lC201). The main cause of failure is often a failure of the IC itself. It is also necessary to be careful of a possible failure of the external components. Because the change of voltage at each pin of the IC is extremely small, it is very difficult to discover a failed element by measuring voltage. 2) Defective horizontal sync: This is due to a failure of IC501 or the horizontal AFC circuit. 3) Defective vertical sync: This is due to a failure of either the separator and amplifier for the vertical synchronous signal, or the vertical oscillator IC501 and its peripheral elements.
