Service Adjustments (Electronic Controls, cont.)

Horizontal Centering

Serviceman DAC Adjustment (D0)
Preparation:

Connect a monoscope pattern generator.

Procedure:

1. In the Serviceman Mode for making electronic

adjustments. Select the Horizontal Centering
Adjustment DAC (D0) and adjust until the center of
the monoscope pattern is centered on CRT.

2. EXIT the Serviceman Adjustment Mode.

MTS Circuit Adjustments

The MTS Circuit Adjustments require two steps:
1. Input Level Adjustment.
2. Stereo Separation Adjustment.

Input Level Adjustment (M0)

Preparation:

1. Connect an RMS meter with filter jig as shown in

Fig. 24.

2. Connect an RF signal generator to the RF

antenna input.

Procedure

1. Apply the following signal from the RF signal

generator:
Video: 100 IRE flat field, 30% modulation.
Audio: 300Hz, 100% modulation, monaural
(70 ±5dB, 75

Ω

OPEN, P/S 10dB).

2. Adjust the MTS Input Level Adjustment (M0) until

the voltage measured is 106 ± 6.0mV rms.

Stereo Separation Adjustment (M1 & M2)

Preparation:

1. Connect an RF signal generator to the RF antenna

input.

2. Connect a scope to TPE10.

Procedure:

1. Select Stereo Mode in Audio menu
2. Apply the following signal from the RF signal

generator:
Video: 100 IRE flat field, 30% modulation.
Audio: 300Hz, 100% modulation, stereo (left only)
(70 ±5dB, 75

Ω

OPEN, P/S 10dB).

3. Adjust the MTS Low-Level Separation Adjustment

(M1) until the amplitude displayed on the scope
is minimum.

4. Apply the following signal from the RF

signal generator:
Video: 100 IRE flat field, 30% modulation.
Audio: 3KHz, 100% modulation, stereo (left only)
(70 ±5dB, 75

Ω

OPEN, P/S 10dB).

5. Adjust the MTS High-Level Separation Adjustment

(M2) until the amplitude displayed on the scope is
minimum.

6. Repeat above steps 2 through 5 until the amplitude

is at minimum for both signals.
