Adjustment Procedure:
1. Connect a digital voltmeter to the TP1 (5.35 V) on the A board.
2. Adjust RV501 on the A board so that digital voltmeter reading

is 5.35 V.

Adjustment Procedure:
1. Connect a frequency counter to the CL299 on the A board.
2. Adjust RV502 on the A board so that frequency counter read-

ing is 115 ± 2 kHz.

The measuring equipment below are used for these electrical
adjustments:
• Oscilloscope
• NTSC pattern generator
• PAL pattern generator
• Regulated DC power supply
• Digital voltmeter

Unless otherwise specified, the measuring equipment should be
connected as shown below:

1. Press the 

[SEL]

 button of the wireless remote commander, set

the image quality of the set to “VISUAL STD”.

2. The adjustment signal is a 5-step gray scale signal from a NTSC

pattern generator.
Input the gray scale signal into the tuner unit and connect an
oscilloscope to TP415 on the G board. Check that the width
between the black and white levels of the gray scale signal is
0.74 Vp-w.

Adjustment Procedure:
1. Display the gray scale on the monitor screen.
2. Connect a digital voltmeter to TP (BRIGHT) on the G board.
3. Adjust RV405 so that the reading on the digital voltmeter is

2 V.

Adjustment Location: See page 13.

Ω

Adjustment Procedure:
1. Display the gray scale on the monitor screen.
2. Connect an oscilloscope to TP (COM) on the G board.
3. V COM Amplitude Adjustment

Adjust RV401 so that the amplitude of the output waveform is
6.0 V.

4. V COM Bias Adjustment

Adjust RV409 so that the level A of the output waveform is at
4.3 V DC.

Adjustment Location: See page 13.

Adjustment Procedure:
1. Display the gray scale on the monitor screen.
2. Connect a oscilloscope to TP (G) on the G board.
3. Adjust RV406 so that the white and the next step of pedestal

are on the same level.

Adjustment Location: See page 13.

γ

Adjustment Procedure:
1. Display the gray scale on the monitor screen.
2. Connect an oscilloscope to TP (G) on the G board.
3. Adjust RV407 so that the third step from the bottom becomes

1.2 V.

Adjustment Location: See page 13.
