IMPORTANT SERVICE SAFETY INFORMATION

Operation of receiver outside of cabinet or with back remov ed involv es a shock hazard. Work on these models should only be performed by those who are thoroughly familiar with precautions necessary when working on high voltage equipment.

Exercise care when servicing this chassis with power applied. Many B plus and high voltage RF terminals are exposed which, if carelessly contacted, can cause serious shock or result in damage to the chassis. Maintain connecting ground lead connections between chassis, escutcheon, picture tube dag and tuner cluster when operating chassis.

These receivers have a “Polarized” AC line cord. The AC plug is designed to fit into standard AC outlets in one direction only. The wide blade connects to the “ground side” and the narrow blade connects to the “hot side” of the AC line. This assures that the TV receiver is properly grounded to the house wiring. If an extension cord must be used, make sure it is of the “polarized” type.

When it is necessary to make measurements or tests with AC power applied to the receiver chassis, an Isolation T ransf ormer must be used as a safety precaution and to prev ent possible damage to transistors. The Isolation Transformer should be connected between the TV line cord plug and the AC power outlet.

Certain HV failures can increase X-ray radiation. Receivers should not be operated with HV levels exceeding the specified r ating for their chassis type. The maximum operating HV specified for the chassis used in these receivers is 25 KV ± 1.0KV at zero beam current with a line voltage of 120V AC. Higher voltage may also increase possibility of failure in HV supply.

It is important to maintain specified values of all components in the horizontal and high voltage circuits and anywhere else in the receiver that could cause a rise in high voltage, or operating supply voltages. No changes should be made to the original design of the receiver.

PROTECT YOUR CUSTOMER

1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the receiver.

2. Replace all protective devices such as non-metallic control knobs, insulating fishpapers, cabinet backs, adjustment and compartment covers or shields, isolation resistor capacitor networks, mechanical insulators, etc.

3. T o be sure that no shoc k hazard e xists, a chec k f or the presence of leakage current should be made at each exposed metal part having a return path to the chassis (antenna, cabinet metal, screw heads, knobs and/or shafts, escutcheon, etc.) in the following manner.

Plug the AC line cord directly into a 120V AC receptacle . (Do not use an Isolation Transformer during these checks) All checks must be repeated with the AC line cord plug connection rev ersed. (If necessary, a non-polarized adapter plug must be used only for the purpose of completing these checks.)

If available , measure current using an accurate leakage current tester. (Use Standard Item No. 25086,21641) Any reading of 0.4 mA or more is excessive and indicates a potential shock hazard which must be corrected before returning the receiver to the owner.

If a reliable leakage current tester is not availab le, this alternate method of measurement should be used. Using tw o clip leads, connect a 1500 ohm, 10 watt resistor paralleled by a 0.15 MF capacitor in series with a known earth ground, such as a water pipe or conduit and the metal part to be checked. Use a VTVM or VOM with 1000 ohms per volt, or higher sensitivity to measure this AC voltage drop across the resistor . Any reading of 0.61 volt RMS or more is excessive and indicates a potential shock hazard which must be corrected before returning the receiver to the owner .

Components shown in the shaded areas on the schematic diagram or identified by the safety mark in the replacement parts list should be replaced only with exact Factory recommended replacement parts. The use of unauthorized substitute parts may create shock, fire, X-radiation or other hazard.

To deter mine the presence of high voltage, use an accurate high impedance HV meter connected between second anode lead and the CRT dag grounding device. When servicing the High Voltage System remove static charge from it by connecting 10K ohm resistor in series with an insulated wire (such as a test probe) between picture tube dag and 2nd anode lead (AC line cord disconnected from AC supply).

The picture tube used in this receiver employs integral implosion protection. Replace with tube of the same type number f or continued safety. Do not lift picture tube by the neck. Handle the picture tube only when wearing shatter-proof goggles and after discharging the high voltage completely. Keep others without shatter-proof goggles away .

When removing springs or spring mounting parts from tuner, tuner cluster or chassis, shatter-proof goggles must be worn. Keep others without shatter-proof goggles away.

COLOR PURITY ADJUSTMENT

For best results, it is recommended that the purity adjustment be made in the final receiver location. If the receiver will be moved, perform this adjustment with it facing East. The receiver must have been operating 15 minutes prior to this procedure and the face plate of the CRT must be at room temperature. The following procedure is recommended while using a Dot/Bar Generator.

1. Check correct location of all neck components. (Refer to Fig. 3)

2. Rough-in the static convergence at the center of the CRT, as explained in the static convergence procedure.

3. Set the Contrast control to minimum position and Brightness control as far maximum as possible without causing the picture to “bloom”.

STATIC CONVERGENCE ADJUSTMENT ( Refer to Figure 3 and 4 )

IMPORTANT: Before proceeding, make sure the location of the convergence magnet assembly on the neck of the CRT is as shown in Figure 3. The rear edge of this assembly must be positioned 65 mm from the tip of the CRT base. If not properly positioned, convergence adjustment may be difficult, if not impossible.

1. Apply dot or crosshatch pattern from Dot/Bar Generator to receiver. Reduce setting of Brightness and/or Contrast controls to eliminate any blooming in pattern.

2. Observe the blue and red pattern appearing on the CRT screen. Locate the 4 pole magnet rings and separate their adjusting tabs approximately the width of one tab.

3. Now rotate this pair of magnet rings as a unit without re-adjusting the spacing between the tabs. This will minimize the separation between the blue and red dots (lines).

4. If the blue and red dots are not completely converged at this point, readjust the spacing between the two tabs to complete convergence of the blue and red dots (lines), thus producing magenta dots (lines).

5. If necessary, repeat step 2, 3 and 4 until proper convergence is achieved.

6. Observe the magenta (B/R) and green pattern now appearing on the CRT screen.

7. Locate the 6 pole magnet rings and separate their adjusting tabs approximately the width of one tab.

8. Rotate this pair of magnet rings as a unit without re-adjusting the spacing between the tabs. This will minimize the separation between the magenta (B/R) and green dots ( lines).

9. If the magenta and green dots (lines) are not completely converged at these points, readjust the

spacing between the two tabs to complete convergence of the magenta and green dots (lines).

10. If necessary, repeat step 7, 8 and 9 until proper convergence is obtained.

To prevent accidental mis-adjustment of the magnets, apply a stripe of paint across all six rings and onto the neck of the CRT.

FIG. 4

DYNAMIC CONVERGENCE ADJUSTMENT ( Refer to Figure 5)

Dynamic convergence (convergence of the three edges of the CRT screen) is accomplished by proper insertion and positioning of three rubber wedges between the edges of the deflection yoke and funnel of the CRT. This is accomplished in the following manner.

1. Turn the receiver ON and allow it to warm up for 15 minutes.

2. Apply crosshatch pattern from Dot/Bar Generator to receiver. Observe spacing between lines around

edges of CRT screen.

3. For the misconvergence shown in Figure 5 ( A ), tilt the deflection yoke down and insert wedge A between deflection yoke and CRT.

4. For the misconvergence shown in Figure 5 ( B ), tilt the deflection yoke up and insert wedge B between deflection yoke and CRT.

5. For the misconvergence shown in Figure 5 ( C), tilt left side of the deflection yoke and slightly insert wedge C between deflection yoke and CRT. Then, deeply insert wedges A and B between deflection yoke and CRT.

6. For the misconvergence shown in Figure 5 ( D ), tilt right side of the deflection yoke and deeply insert wedge C between deflection yoke and CRT. Then, slightly insert and/or extract wedges A and B between deflection yoke and CRT.

7. Alternately change spacing between and depth of insertion of the three wedges until proper dynamic convergence is obtained.

8. Use a strong adhesive tape to firmly secure each of the three rubber wedges to the funnel of the CRT.
