SAFETY PRECAUTIONSWARNING: The chassis of this receiver has a floating groundwith the potential of one half the AC line voltage in respect toearth ground. Service should not be attempted by anyone notfamiliar with the precautions necessary when working on thistype of equipment. The following precautions must be observed:

1. An isolation transformer must be connected in the power linebetween the receiver and the AC line before any service isperformed on the receiver.

2. Comply with all caution and safety-related notes provided onthe side of the cabinet, inside the cabinet, on the chassis, andthe picture tube.

3. When replacing a chassis in the cabinet, always be certainthat all the protective devices are installed properly, such ascontrol knobs, adjustment covers, shields and barriers.

DO NOT OPERATE THIS TELEVISION RECEIVER WITHOUT THE PROTECTIVE SHIELD IN POSITION ANDPROPERLY SECURED.

4. Before replacing the back cover of the set, thoroughly inspectthe inside of the cabinet to see that no stray parts or toolshave been left inside.Before returning any television to the customer, the service technician must perform the following safety checksto be sure that the unit is completely safe to operate withoutdanger of electrical shock.

ANTENNA COLD CHECKRemove AC plug from the 120 VAC outlet and place a jumperacross the two blades. Connect one lead of an ohmmeter to thejumpered AC plug, and touch the other lead to each exposedantenna terminal (UHF and VHF antenna terminals). The resis-tance must measure between 1M ohm and 5.2M ohm. Anyresistance value below or above this range indicates an abnor-mality which requires corrective action.

LEAKAGE CURRENT CHECKPlug the AC line cord directly into a 120 VAC outlet. (Do not usean isolation transformer for this check.) Use an AC voltmeter,that has 5000 ohms per volt or more sensitivity. Connect a 1500ohm 10 watt resistor, paralleled by a 0.15 µF 150 VAC capacitor,between a known good earth ground (water pipe, conduit, etc.)and all exposed metal parts of the cabinet (antennas, handlebracket, metal cabinet, screw heads, metal overlays, controlshafts, etc.). Measure the AC voltage across the 1500 ohmresistor. The AC voltage should not exceed 750 mV. A readingexceeding 750 mV indicates that a dangerous potential exists.The fault must be located and corrected. Repeat the above testwith the receiver power plug reversed.

NEVER RETURN A RECEIVER TO THE CUSTOMER WITHOUT TAKING THE NECESSARY CORRECTIVEACTION.

X-RADIATION PRECAUTIONThe primary source of X-RADIATION in solid-state receivers is thepicture tube. The picture tube is specially constructed to limit X-Rayemission. For continued X-RADIATION protection, the replacementtube must be the same type as the original (including the suffix let-ter in the part numbers). Excessive high voltage may producepotentially hazardous X-RADIATION. To avoid such hazards, thehigh voltage must be maintained within specific limits. Refer to the X-RADIATION WARNING NOTE on the CHASSIS SCHEMATIC inthis service manual for specific high voltage limits. If the high volt-age exceeds specified limits, check the components specified onthe chassis schematic diagram and take the necessary correctiveaction. Carefully follow the instructions for the +B Voltage Checkand the High Voltage Check to maintain the high voltage within thespecified limits.

HIGH VOLTAGE HOLD-DOWN TESTTo prevent X-RADIATION from the picture tube due to excessivehigh voltage, a HOLD-DOWN circuit is provided in the high volt-age circuit. Every time the receiver is serviced, the high voltageHOLD-DOWN circuit must be tested for proper operation. Referto the HIGH VOLTAGE HOLD-DOWN TEST in service adjust-ments.

PRODUCT SAFETY NOTICEWhen replacing components in a receiver, always keep in mindthe necessary product safety precautions. Pay special attentionto the replacement of components marked with a star ( ) in theparts list and in the schematic diagrams. To ensure safe productoperation, it is necessary to replace those components with theexact same PARTS.

13. Check the purity of the red and blue screens for uniformity.Turn off other colors to check (use bias controls) or use generator. If necessary, readjust the yoke position until allscreens are pure.

14. If bias controls and screen control were used to set purity,reset Grayscale and Brightness Level. Refer to GrayscaleAdjustment on page 6 and Brightness Level Adjustment onpage 7.

15. Confirm that the yoke is not tilted. Tighten the yoke mounting screw. Adjust convergence next.

CAUTION: Purity and Convergence adjustments have been made at the factory. Readjustments should be madeonly after the picture tube or deflection yoke is replaced. Follow the steps below for the necessary readjustments.

CONVERGENCE ADJUSTMENT

CENTER CONVERGENCE ADJUSTMENT1. Connect a crosshatch generator to antenna terminals.2. Set Contrast control to low level to eliminate Blooming.

Reduce Brightness level to obtain black background if necessary.

3. Adjust the angle between the four-pole magnet tabs 1 and 2(Figure 2), and superimpose the red and blue vertical linesin the center area of the picture screen. See Figure 4.

4. Keeping the tabs at the same angle, rotate them together tosuperimpose the blue and red horizontal lines in the centerarea of the picture screen. See Figure 4.

5. Adjust the six-pole magnet tabs 3 and 4 so the convergedred/blue line is superimposed on the green line. This is thesame procedure used in Steps 3 and 4. See Figure 5.

OUTER AREA CONVERGENCE ADJUSTMENTThe outer area convergence is performed by positioning of theyoke as follows:

1. Move the top of the yoke toward or away from the picturetube. This movement will affect the vertical lines at the topand bottom and the horizontal lines at the sides. See Figure 6.

2. Check that splits at 12 O’Clock and 6 O’Clock positions areminimized, adjust yoke for best compromise. Secure withwedge at 12 O’Clock position. See Figure 1.

3. Move the side of the yoke toward or away from the picturetube to converge the horizontal lines at the top and bottomand the vertical lines at the sides. See Figure 7.

4. Check that splits at 12 O’Clock and 6 O’Clock are minimized, adjust yoke for best compromise. Secure yokeposition with the side wedges. See Figure 1.

Note: When reusing the rubber wedges, apply a small amount of silicone rubber adhesive or hot melt to eachof the wedges.

SERVICE HINTS

POWER FAILURE DETECTOR

This set is equipped with a Power Failure Detector function included in the CPU which checks for an abnormal condition in the chassis power supplies, including the power supply derived from the Horizontal Output Transformer.

If, while the power is on, a failure is caused by any of the following which results in a low voltage supply, the CPU will turn the set offin 1.5 seconds to prevent unnecessary damage:

• Failure within the power supply circuits.

• A short circuit in the load side from the supply.

• Stoppage of the Horizontal Output Oscillator caused by the X-Radiation protection Hold-Down Circuit.

If, while the power is off, the power is switched on and any of these failures remains uncorrected, the CPU will shut off the power within 3 seconds.

Check the following if the set is turned off by the power failure detector.

1. Disconnect the AC power cord (120V AC line) for at least 10 seconds.2. Connect a DC Voltmeter to the following TEST POINTS.

3. Press the power key and check for the proper voltage supplies.4. If any of these voltages is low, the power failure detector should turn the set off within 3 seconds.5. Check all circuits listed above.

Note: This set is equipped with a Power Surge Protection feature included in the CPU. If power failure occurs three times within 15minutes, the CPU will automatically stop functioning to help prevent secondary damage. (TV will not turn on by pressing thepower key.) To reset the operating programs within the CPU, disconnect the AC power cord for at least 10 seconds.

SCHEMATIC DIAGRAMSNOTES ON SCHEMATIC DIAGRAM1. All resistance values in ohms K=1,000 M=1,000,000.2. Unless otherwise noted on schematic, all capacitor values less than 1 are expressed in µF (Micro Farad), and the

values more than 1 are in pF.3. Unless otherwise noted on schematic, voltage reading taken with VOM from point indicated to chassis ground.

Voltage reading taken using offset color bar-signal on VHF channel 5, all controls at normal. Line voltage at 120 volts. Some voltages may vary with signal strength.

4. Waveforms were taken with offset color-bar signal and controls adjusted for normal picture. Waveforms marked withan may vary with signal strength.

5. Symbol indicates a fusible resistor, which protects the circuit from possible short circuits.

PRODUCT SAFETY NOTICETHE COMPONENTS DESIGNATED BY A STAR ( ) ON THIS SCHEMATIC DIAGRAM DESIGNATE COMPONENTSWHOSE VALUES ARE OF SPECIAL SIGNIFICANCE TO PRODUCT SAFETY. SHOULD ANY COMPONENT DESIGNATED BY A STAR NEED TO BE REPLACED, USE ONLY THE PART DESIGNATED IN THE PARTS LIST. DONOT DEVIATE FROM THE RESISTANCE, WATTAGE AND VOLTAGE RATINGS SHOWN.

SERVICE NOTES:1. When replacing parts on circuit boards, clamp the lead wires to terminals before soldering.2. When replacing high wattage resistors on circuit board, keep the resistor body 10 mm (3/8”) from circuit board.3. Keep wires away from high voltage and high temperature components.

X-RADIATION WARNING NOTETHIS TV CONTAINS CRITICAL PARTS TO PROTECT AGAINST X-RADIATION. NORMAL 2ND ANODE VOLTAGE IS26.0KV AT ZERO BEAM CURRENT AT 120 VOLTS AC LINE, AND MUST NOT EXCEED 27.0KV UNDER ANYOPERATING CONDITION. SEE HIGH VOLTAGE CHECK ON PAGE 7.
