Before You Start... You should never attempt to work on an exposed monitor chassis if you are not familiar with servicing procedures and precautions necessary for highvoltage equipment. Any TV monitor has three sources of possible danger: strong electric shock due to high voltages or unisolated AC line voltages, X-ray radiation, and implosion. Therefore, please read this chapter carefully. B. Safety Measures Develop good safety habits, so when you're rushed with repair work, you'll still automatically take precautions. A good practice when working on any TV monitor is to first ground the chassis and use only one hand when testing circuitry. This will avoid the possibility of carelessly putting one hand on the chassis or ground, and the other on an electrical connection. Doing so could cause a severe electrical shock. Figure 1 If you service this color monitor on a test bench, you must isolate the monitor from AC line voltage! An isolation transformer is mandatory for your own safety. The Sanyo monitor does not contain an isolation transformer on its chassis. It is mounted instead on the game power supply. (It may appear like a regular power transformer, but is really also an isolation transformer.) C. Picture·Tube Handling Use extreme care when handling the picture tube, since rough handling may cause it to implode, due to a vacuum inside. Do not nick or scratch the glass, or subject it to any undue pressure when removing or installing it. Wear safety goggles and heavy gloves for protection when handling the picture tube. Keep others without safety goggles away. Do not lift the tube by the neck. Overview of Sanyo 14" Color TV Monitor 1 Sanyo Color Monitor Discharge the high voltage in the picture tube by shorting the anode connection to chassis groundnot the cabinet or other mounting parts. When discharging, go from ground to anode, and use a well-insulated piece of wire. D. Replacing with Proper Components It is important to maintain the specified values and failure characteristics of all components in the horizontal and high-voltage circuits, and anywhere else in the monitor that could cause a rise in high voltage, or in operating supply voltages. Refer to the parts lists in the back of this manual, and use only exact replacement parts, especially for the picture tube, semiconductors, transformers, coils, and fuses. 2 If you replace the picture tube with another type not specified in the parts list, then avoid prolonged exposure at close range to the unshielded areas of the tube. You may endanger yourself from unnecessary exposure to X-ray radiation. E. Final Testing Before Reinstalling Monitor Before installing the color monitor back in the game, you must check the following: 1. Inspect all harness wiring on the monitor and be sure none of it is pinched between the chassis and other metal parts in the monitor. 2. Replace all protective devices such as insulating fishpaper, compartment covers and shields. Sanyo Color Monitor 2 Specifications A.

Brightness Remember to observe the precautions regarding high voltages when you make any adjustments on this monitor! However, if you cannot achieve the proper brightness by using this white adjustment knob, then you should check the master brightness level adjustment. This potentiometer is located almost dead center on the Main PCB, at VR201. Note that before you adjust the brightness, the monitor should have been turned on for at least 5 minutes. Keep the game in the attract or play mode. Find the small white knob underneath the screen, located at the far right on the Control Printed-Circuit Board or PCB (see Figure 2). Turn this brightness or screen voltage control until you achieve a pleasing level of brightness. To reset the brightness level, disconnect the 6-pin video-signal connector from the monitor. Turn the white brightness control to maximum or fully clockwise. Connect a DC voltmeter's plus lead to TP452, and its minus lead to TP451-near the center of the Main PCB. Too high a brightness causes the retrace lines to show. Too low a brightness causes the entire screen to become dark and obscured. Set the voltmeter to the 1.5-3 V range. Now adjust the small VR201 potentiometer to 0.5 volts. Reconnect the 6-pin connector on the monitor. HORIZONTAL HOLD VERTICAL HOLD VERTICAL HEIGHT MAIN PCB BRIGHTNESS LEVEL ~ TP451 TP452 0 0 HORIZONTAL WIDTH ADJUST· MENT COIL B + ADJUSTMENT (For Technicians Only) Figure 2 4 @ Adjustable Controls on Main PCB and Control PCB Sanyo Color Monitor B. Horizontal Hold Use this adjustment if the picture drifts sideways across the screen. Find the second potentiometer from the right, on the Control PCB (as you face the monitor's screen)-see Figure 2. Turn the pot until the black lines no longer slant downwards or upwards, and you obtain a normal screen image. C. Vertical Hold ( convergence grid and dots. Locate the vertical height control on the monitor's Control PCB: it is the knob on the far left underneath the screen. Turn this control until the top and bottom grid lines run along the edges of the screen. The lines should not disappear off the edges, which would indicate overscanning. E. Horizontal Width Before using this control, be sure the monitor has been turned on for 5 minutes or more. If the screen image is too wide or narrow, you should use this control to adjust it for proper width. Use this adjustment if the picture drifts straight up or down on the screen. The vertical hold control is the second potentiometer from the left, on the Control PCB (as you face the monitor's screen)see Figure 2. Set the game for the diagnostic that displays the convergence grid and dots. Locate the horizontal width control on the monitor's Main PCB: it is the coil at the center of this board, directly underneath the yoke. Be sure to use only a non-metal Allen wrench (commonly called a "tweaking" tool) for this adjustment! Turn this control until the right and left grid lines run along the edges of the screen. The lines should not disappear off the edges, which would indicate overscanning. Turn this control in either direction until the picture no longer drifts straight up or down on the screen. D. Vertical Height If the screen image is not large enough or too large vertically, then you can adjust it very easily with this control. Using this control will stretch or compress the image vertically. The vertical height control affects the spacing between the raster lines equally. Set the game for the diagnostic that displays the F. Focus This control simply changes the sharpness of the screen image. The white focus adjustment knob is located on the plastic bracket above the flyback transformer. Turn this control until you get the optimum screen sharpness possible. TOP GREEN BIAS (CUT-OFF) BLUE BIAS RED BIAS BLUE DRIVE RED DRIVE BOTTOM Figure 3 Adjustable Controls on Neck PCB 5 Sanyo Color Monitor 4 Supply Voltages To test for proper + 105V supply, locate the test point TP91 at the front end of the very large 20-watt resistor R609. This resistor is in the center rear area of the Main PCB. Connect a voltmeter at this point and to ground. Adjust the brightness control on the Neck PCB to maximum. Use the nearby potentiometer (VR601) on the monitor's Main PCB that is labeled "B + ADJUSTMENT" in Figure 2. Turn this pot until the meter reads + 105V. Then return the brightness control to normal. 5 Signal Test Points A. RGB Signals The blue, red, and green signals can be tested at the points labeled ED, EE, and EA, respectively. These are located on the back of the Neck PCB. 6 B. Horizontal and Vertical Sync This synchronization signal can be tested at pin 5 of the 6-pin video signal connector. When using a test prod, do not jam it into the connector pin. Otherwise you will stretch the pin, and it could later fall out of the connector housing. ....... .,, 0 ... :::s ::; s: Q :::s '< 0 m CJ) 0 _.,. 3 ; cc ar c ~ 0 () m .&::a (iJ ce· c 100 ± 10VAC (- SYNC SEPARATOR POWER RECTIFIER SYNC AMPLIFIER VOLTAGE REGULATOR HORIZONTAL OSCILLATOR VERTICAL OSCILLATOR ~- ~· +105V HORIZONTAL DRIVE OVERVOLTAGE PROTECTOR VERTICAL DRIVE R,G,B INTERFACE I PINCUSHION HORIZONTAL DEFLECTION YOKE HORIZONTAL OUTPUT VERTICAL OUTPUT +105V R,G,B OUTPUT -::- ..

Picture Tube Replacement Be sure to first unplug the power and video-signal connectors. Remove monitor assembly from game. 1. Discharge the high voltage from the tube. Remove the large high-voltage anode connector near the top of the picture tube. Unplug the neck board at rear of picture tube. 2. Unplug the degaussing coil 2-pin connector. 3. Unplug the 4-wire connector on Main PCB. Unhook the spring that holds the braided ground wire (near the bottom corner of picture tube). 4. Using a 5/16" hex socket wrench, remove the four screws that hold the picture tube in the steel frame. Carefully remove the tube by pulling it out towards the front. 3. Loosen the Phillips screws that tighten the two neck clamps around the neck. Now. slide the magnet assembly, then the yoke assembly off the end of the picture tube. C. Flyback Transformer Replacement First unplug the power and video-signal connectors. Remove monitor assembly from game. 1. Discharge the high voltage from the tube. Remove the large anode connector at top of picture tube. Also open the white twist-and-tie anode holder and remove the anode wire from this holder. B. Yoke Replacement 2. Unplug the neck board at rear of picture tube. Unplug the two white wires at the very top of the "FOCUS" adjustment bracket. You need to reconverge the picture whenever you replace a yoke. 3. Remove the two small hex nuts and the Phillips screw that secure the flyback transformer cover plate. First unplug the power and video-signal connectors. Remove monitor assembly from game. 4. Unsolder the 9 connections for the transformer on the circuit or bottom side of the Main PCB. 1. Discharge the high voltage from the tube. Unplug the neck board at rear of picture tube. 5. 2. Using a thin knife or single-edged razor blade, carefully loosen the rubber wedges from the picture-tube surface. Now lift out the transformer. When replacing with a new transformer, be sure to check the picture for sharpness. If it's not sharp, adjust the white focus knob on the transformer. I \______/ 8 Sanyo Color Monitor 8 Adjustments A. Purity Adjustments 1. Preliminary First remove the monitor from the game, but leave the connectors still attached. The purity and convergence magnets can be moved without loosening the rear Phillips screw. If you will also be converging the outer area of the picture (see Section 2 on the next page), you should loosen both the deflection yoke and magnet mounting screws at this time. Turn the picture tube so it faces north or south. Then degauss the picture tube with a hand-held degaussing coil. If the magnets have been secured with a white glue, you will find that its hold can be easily broken when you move the magnets. 2. Red Purity Adjustment Refer to Figure 3 and turn off the green and blue guns with the G and B bias or cutoff controls, located on the neck board. (Leave the red gun on.) Display any self-test pattern on the screen that shows solid white. Keep this display throughput the purity adjustments. Rotate and spread the tabs of the purity magnets (the pair farthest towards the front) until you center the screen image vertically and horizontally. You should also obtain a pure red overall. 3. Green Purity Adjustment Turn off the red and blue guns by using the controls on the neck board; leave the green gun on. Readjust the purity magnets if necessary for a uniformly green screen. 5. Final Check As a final check for total color purity, turn on all guns again. Leave the all-white self-test pattern on the screen. The screen should be pure, clean white-not tinted with other hues. Finally, reinstall the monitor in the game. B. Convergence Adjustments 1. Static Convergence (Center Area) First remove the monitor from the game, but leave the connectors still attached. If you will also be converging the outer area of the picture (see Section 2 that follows), you should loosen both the deflection yoke and magnet mounting screws at this time. Display the diagnostics pattern that shows black background with white lines and dots. Keep this display throughout all convergence adjustments. Refer to Figure 3 and turn off the green gun with the G bias or cutoff control, located on the neck board. (Leave the red and blue guns on.) Adjust the angle of the 4-pole or center pair of magnets, and superimpose the red and blue vertical lines in the center area of the screen. Keeping their angles the same, rotate both tabs of the 4-pole magnets to superimpose the red and blue horizontal lines in the center area of the screen. 4. Blue Purity Adjustment Turn on the green gun again. Adjust the angle of the 6-pole or rear pair of magnets, and superimpose the green vertical lines on the red/blue ones, in the center area of the screen. Turn off the red and blue guns by using the controls on the neck board; leave the blue gun on. Repeat the purity adjustment for a uniformly blue screen. Finally, keeping their angles the same, rotate both tabs of the 6-pole magnets to superimpose the green horizontal lines on the red/blue ones. 9 Sanyo Color Monitor FROM r---- - - - - - -- -- -- - - ---- -- - - - - -- I MAIN CHASSIS CIRCUIT BOARD I GROUND BH'~~-----------------------------------+-~vvv---t ~ ~ DRIVE TR 204 - TR 20!0 2SC536 (E,F.

(Otherwise, immediately proceed with Section 2 below.) Slide the yoke slightly away from the picture tube. Up/down movement of the yoke causes the outer edges of the screen image to swivel clockwise or counterclockwise. Side-to-side movement causes the lines and dots at the outer screen edges to expand and contract. 2. Dynamic Convergence (Outer Area) Move the yoke in the up/down and side-to-side directions until the outer lines and dots on the screen are pure white. Be sure to keep the same convergence pattern on the screen-white lines and dots with black background. Using a razor blade or thin knife, carefully loosen the glue holding the three rubber wedges and remove them. Be sure both the magnet and deflection yoke mounting screws are loosened. Then secure the deflection yoke by putting the wedges back in between the picture tube and the yoke's white collar. Secure the wedges with glue. Tighten the screws that secure the deflection yoke clamp and the magnets. 9 Schematic and Illustrated Parts Lists The purpose of this chapter is to provide you with the necessary information for ordering replacement parts for your Sanyo 14" color monitor.
