SAFETY PRECAUTIONS

NOTICE: Comply with all cautions and safety-related notes located on or inside the cabinet and on the chasis or picture tube.

WARNING: Since the chasis of this receiver is connected to one side of the AC power supply during operation, whenever the receiver is plugged in, service should not be attempted by anyone unfamiliar with the precautions necessary when working on this type of receiver.

The following precautions should be observed:

1. Do not install, remove, or handle the picture tube in any manner unless shatterproof goggles are worn. People not so equipped should be kept away from the picture tube while handling.

2. When service is required, an isolation transformer should be inserted between power line and the receiver before any service is performed on a “HOT” chassis receiver.

3. When replacing a chassis in the receiver, all protective devices must be put back in place, such as barriers, nonmetallic knobs, adjustment and compartment covershields, isolation resistors, capacitors, etc.

4. When service is required, observe the original lead dress in the high voltage circuitry area.

5. Always use the manufacturer’s replacement components. Critical components as indicated on the circuit diagram should not be replaced by another manufacturer’s. Furthermore, where a short circuit has occurred, replace those components that indicate evidence of overheating.

6. Before returning a serviced receiver to the customer, the service technician must thoroughly test the unit to be certain that it is completely safe to operate without danger of electrical shock, and be sure that no protective device built into the receiver has become defective, or inadvertently defeated during servicing.

Therefore, the following checks should be performed for the continued protection of the customer and service technician.

Leakage Current Cold Check

With the AC plug removed from the 120V AC 60Hz source, place a jumper across the two plug prongs. Turn the AC power switch ON. Using an insulation tester (DC500V), connect one lead to the jumpered AC plug and touch the other lead to each exposed metal part (antennas, screwheads, metal overlays, control shafts, etc.), particularly any exposed metal part having a return path to the chassis should have a minimum resistor reading of

0.24M

Ω

and a maximum resistor reading of 12M

Ω

. Any resistance value below or above this range indicates an abnormality which requires corrective action. An exposed metal part not having a return path to the chassis will indicate an open circuit.

Leakage Current Hot Check

Plug the AC cord directly into a 120V AC 60Hz outlet (do not use an isolated transformer for this check). Turn the

AC power ON. Using a Leakage Current Tester

(Simpson’s Model 229 or equivalent), measure for current from all exposed metal parts of the cabinet (antennas, screwheads, overlays, control shafts, etc.). Any current measured must not exceed 0.5 milliamps.

Notices” in this Service Manual.

For continued X-Radiation protection, replace picture tube with original type or HITACHI equivalent type.

POWER SOURCE

This television receiver is designed to operate on 120Volt/

60Hz, AC house current. Insert the power cord into a

120Volts/60Hz outlet.

NEVER CONNECT THE TV TO OTHER THAN THE

SPECIFIED VOLTAGE OR TO DIRECT CURRENT.

Service Notes

Equipment needed to check the disabled circuit: IMPORTANT: To protect against possible damage to the solid state devices due to arcing or static discharge, make certain that all ground wires and CRT

DAG wire are securely connected.

1. Voltmeter (0 - 200V scale)

2. High Voltage Meter (0- 50kV)

CAUTION: The power supply circuit is above earth ground and the chassis cannot be polarized. Use an isolation transformer when servicing the Receiver to avoid damage to the test equipment or to the chassis.

Connect the test equipment to the proper ground ( ) or

( ) when servicing, or incorrect voltages will be measured.

WARNING: This Receiver has been designed to meet or exceed applicable safety and X-ray radiation protection as specified by government agencies and independent testing laboratories.

To maintain original product safety design standards relative to X-ray radiation and shock and fire hazard, parts indicated with the symbol

!

on the schematic must be replaced with identical parts. Order parts from the manufacturer’s parts center using the parts numbers shown in this service manual, or provide the chassis number and the part reference number.

For optimum performance and reliability, all other parts should be replaced with components of identical specification.

Horizontal Oscillator Disable Circuit

This chassis employs a special circuit to protect against excessive high voltage and beam current. If, for any reason, the high voltage and beam current exceed a predetermined level this protective circuit activates and detunes the horizontal oscillator that limits the high voltage. The over-voltage protection circuit is not adjustable. However, if components indicated by the symbol

!

on the schematic in either the horizontal sweep system or the over-voltage protection circuit itself are changed, the operation of the circuit should be checked using the following procedure:

3. Variac or Isolation Transformer

Procedure:

1.

Tune in a station to verify that the horizontal is in sync.

2.

Obtain a Monoscope pattern or a signal generator crosshatch pattern

3.

Turn the Receiver OFF. Connect a jumper across

IC803 pin 3 and pin 4. Apply +9V DC to cathode of

D001.

4.

Reduce the AC supply voltage to approximately

45V. Connect the high voltage meter to the CRT anode. (H.V. button).

Note: Use the Dag Ground (C10 on the CRT Board)

to connect the (-) lead of the meter.

5.

Turn the Receiver ON. Slowly increase the AC supply voltage and verify that the high voltages does not exceed 37.1kV, when horizontal just begins to pull out of sync. If the high voltage is not within the specified limit, the cause must be determined and corrected before the Receiver is returned to the customer.

Purity and Convergence Procedure

Adjustment is necessary only if the CRT or the deflection yoke is replaced or if the setting was disturbed. The complete procedure consists of:

1.

Vertical Raster Shift Adjustment. (Only for Models

with Purity/Convergence Assembly with 4 Pairs

of Rings).

2.

Initial static convergence.

3.

Setting the purity.

4.

Final static convergence.

When the CRT or the Yoke is Replaced

Place the yoke on the CRT neck (do not tighten the clamp).

For a 2-piece assembly (see Fig. 4):

Position purity/convergence assembly as shown and tighten clamp snugly. Remove the hot-melt glue seal on assembly and position like tabs of purity device together at 12 o’clock to reduce its magnetic field effect.

For a 1-piece assembly (see Fig. 7):

Position like tabs of purity devices together at 12 o’clock to reduce any magnetic field effect. (For better results, note part number and look for specifications at

Service Center)

For either assemblies:

Turn the Receiver ON. Operate the Receiver for 60 minutes using the first Purity Check field (white screen) to stabilize the CRT.

Vertical Raster Shift Adjustment

(Only for

Models with Purity/Convergence Assembly with 4

Apply a green pattern with a horizontal line, adjust the

Deflection Yoke so that has no tilt, then secure it.

Adjust center line of the pattern with the mechanical center of the CRT, this center is determined by two marks at the side edges of the screen. To adjust the line, once the vertical raster shift tabs are place at 3 o’clock to reduce its magnetic field effect (see Fig. 5 and Fig. 6) open the tabs the same angle from the center, until the center line of the pattern becomes a straight line, centered with the marks of the CRT. (see

Fig. 8)

Initial Center Static Convergence

Connect a dot/cross hatch generator to the Receiver and tune in a signal. Observe misconvergence at center of the screen only.

Adjust the R&B pole magnets; by separating tabs and rotating to converge blue with red.

Adjust the R&B and R&B&G pole magnets: by separating tabs and rotating to converge blue and red

(magenta) with green.

Note: Precise convergence at this point is

not important.

Purity Adjustment

When the Receiver is in the Serviceman Mode for making electronic adjustments, press the Recall button on the Remote Control to enter Purity Check. (See the

Service Adjustments Electronic Controls

procedure).

Operate the Receiver for 60 minutes using the first

Purity Check field (white screen) to stabilize the CRT.

Fully degauss the Receiver by using an external degaussing coil.

Press the Recall button on the Remote Control again until the Purity Check (green screen) appears.

For a 2-piece assembly (see Fig. 4):

Loosen the deflection yoke clamp screw and move the deflection yoke back as close to the purity magnet as possible.

Adjust the Purity rings to set the vertical green raster precisely at the center of the screen (see Fig. 9).

Final Convergence Procedure

(see Fig. 10 through Fig. 12):

Note: Vertical size and focus adjustments must be

completed prior to performing the convergence adjustment. Connect a dot pattern generator to the

Receiver. The Brightness level should not be higher than necessary to obtain a clear pattern.

Converge the red and the blue dots at the center of the screen by rotating the R&B pole Static Convergence

Magnets.

Align The converged red/blue dots with the green dots at the center of the screen by rotating the R&B&G pole

Static Convergence Magnets. Melt wax with soldering iron to reseal the magnets.

Slightly tilt vertically and horizontally (do not rotate) the deflection yoke to obtain a good overall convergence.

If convergence is not reached at the edges, insert permalloy (see following section) from the DY corners to achieve proper convergence. Recheck for purity and readjust if necessary.

After vertical adjustment of the yoke, insert wedge at

11 o’clock position, then make the horizontal tilt adjustment.

Secure the deflection yoke by inserting two side wedges at 3 and 7 o’clock positions.

Apply adhesive between tab (thin portion) of wedge and CRT and place tape over the tab to secure to the CRT.

NOTES:

1. CRT warm up with white screen

(three guns activated) is needed to stabilize the shadow mask expansion.

2. Initial center static convergence

(roughly centers three gun beams) is required in order to perform purity adjustment.

Figure 9. Green Raster Adjustment

Green Raster

Slowly move the deflection yoke forward until the best overall green screen is displayed.

For a 1-piece assembly (see Fig. 7):

Slowly move the deflection yoke and purity rings assembly toward the CRT board and adjust the purity magnet rings to set vertical green raster at center of screen (see Fig. 9).

Gradually move the deflection yoke & purity rings forward and adjust for best overall green screen.

Continue from here for either assemblies:

Tighten the deflection yoke clamp screw.

Press the Recall button on the Remote Control again until the purity check (blue screen) and (red screen) appear and observe that good purity is obtained on each respective field.

Press the Recall button on the Remote Control again until Purity check (white screen) appears. Observe the screen for uniform white. If purity has not been achieved, repeat the above procedure.

Permalloy Convergence Corrector Strip

(Part No. 0FMK014ZZ)

This strip is used in some sets to match the yoke and

CRT for optimum convergence. If the yoke or CRT is replaced, the strip may not be required.

First converge the set without the strip and observe the corners.

If correction is needed:

1.

Place strip between CRT and yoke, in quadrant needing correction. Slowly move it around for desired results.

2.

Press adhesive tightly to the CRT and secure with tape.
