2. Alignment and Adjustments
2-1 General Alignment Instructions

1. Usually, a color TV-VCR needs only slight touch-up 5. Avoid overload. Excessive signal from a sweep
adjustment upon installation. generator might overload the front-end of the TV.
Check the basic characteristics such as height, When inserting signal markers, do not allow the marker
horizontal and vertical sync and focus. generator to distort test results.

2. Observe the picture for good black and white 6. Connect the TV only to an AC power source with voltage
details. There should be objectionable color shading; and frequency as specified on the backcover ameplate.
if color shading is present, demagnetize, perform purity
and convergence adjustments described below. 7. Do not attempt to connect or disconnect any wires while
the TV is turned on. Make sure that the power cord is
3. Use the specified test equipment or its equivalent. disconnected before replacing any parts.

4. Correct impedance matching is essential. 8. To protect against shock hazard, use an isolation
transformer.

2-2 Automatic Degaussing
A degaussing coil is mounted around the picture tube, If the chassis or parts of the cabinet become
so that external degaussing after moving the TV should magnetized, poor color purity will result. If this happens,
be unnecessary. But the receiver must be properly use an external degaussing coil. Slowly move the
degaussed upon installation. degaussing coil around the faceplate of the picture tube
and the sides and front of the receiver. Slowly withdraw
The degaussing coil operates for about 1 second after the coil to a distance of about 6 feet before turning
the power is switched ON. If the set is moved or turned power OFF.
in a different direction, the power should be OFF for at
least 10 minutes. If color shading persists, perform the following Color
purity and Convergence adjustments.

2-3 High Voltage Check
CAUTION : There is no high voltage adjustment on this
chassis. The B+ power supply should be +135 volts (with
full color- bar input and normal picture level).

1. Connect a digital voltmeter to the second anode of the
picture tube.

2. Turn on the TV. Set the Brightness and Contrast
controls to minimum (zero beam current).

3. Adjust the Brightness and contrast controls to both
extremes. Ensure that the high voltage does not exceed
30 KV under any conditions.
