V COM Adjustment

Procedure :

1. Connect the oscilloscope to CL44 on the monitor main board.

2. Adjust RV210 (V COM AMP) & RV211 (V COM BIAS) so that the output waveform is within the standards.

3. Repeat step 2 until the standards are satisfied.

Standard values :

A : Adjust RV210 so the value is 4.9 ± 0.1 Vp-p. B : Adjust RV211 so the value is 5.1 ± 0.1 V.

TUNER UNIT SECTION

• Use the following equipment for the electrical adjustment.

Equipment

1 Monitor TV (XVM-6100MK2, etc.) 2 Spectrum analyzer 3 TV signal generator 4 Digital voltmeter 5 Oscilloscope 6 Audio analyzer 7 DC power supply 8 Frequency counter

Equipment Connections

Connect the test equipment as shown in the figure below (unless otherwise instructed) and perform the adjustment.

TRAP Adjustment

Procedure:

1. With the Power off, input the output of TG to TP30 (with DC cut by a capacitor (0.01 µF)).

2. Connect a spectrum analyzer to TP31 (with DC cut by a capacitor (0.01 µF)).

3. Adjust T1 so that the waveform peak is 40.9 MHz ± 50 Hz.

4. Adjust T2 so that the waveform peak is 31.9 MHz ± 50 Hz.

5. After this adjustment, open TP30 and TP31. (Disconnect the spectrum analyzer.)

Connection points: Refer to page 12. Adjustment points: Refer to page 12.

T1= 40.9 MHz T2= 31.9 MHz

VCO Adjustment

Procedure:

1. No connection to ANT IN. (no signal state)

2. Connect a resistor (10 kΩ) between TP33 and +9 V (TP35).

3. Connect a spectrum analyzer to TP34 (with DC cut by a capacitor (0.01 µF)).

4. Adjust T3 so that the waveform peak is 38.9 MHz ± 1 kHz.

5. After this adjustment, open TP34. (Disconnect the spectrum analyzer.)

38.9 MHz

AGC Adjustment

Procedure:

1. Set the TV SYSTEM switch to 1.

2. Input a color bar signal of E8ch (196.25 MHz) and 66 dBµV (75 Ω OPEN).

3. Connect the digital voltmeter to TP42.

4. Adjust VR1 so that reading on the digital voltmeter is

6.0 ± 0.1 V.

AFT Adjustment

Procedure:

1. Input a color bar signal of E8ch (196.25 MHz) and 74 dBµV (75 Ω OPEN).

2. Connect the oscilloscope to TP102.

3. Adjust T3 untill the waveform on the oscilloscope is 2.5 Vp-p.

2.5 Vp-p 0 V

Note: Small peaks (dips) coming out from the top of the

waveform are unacceptable.

RGB Decoder FO Adjustment

Procedure:

1. Without INPUT1, INPUT2 inputs (no signal input mode), short the jumper wire between TP100 and GND.

2. Connect a frequency counter to TP61.

3. Adjust VR6 so that reading on frequency counter is

4.433619 MHz ± 10 Hz.

4. Short the jumper wire between TP106 and GND.

5. Connect a frequency counter to TP61.

6. Confirm that reading on frequency counter is 3.579545 MHz ± 100 Hz.

7. After this adjustment, remove the jumper wires.

RGB Decoder Input Level Adjustment

Procedure:

1. Input signal : PAL EBU color bar (INPUT 1 VIDEO)

2. Adjust VR4 so that the white peak 1 (100% white) of TP111 (B OUT) is at 1.0 Vp-p.

DL AMP & DAT Adjustment

Procedure:

1. Adjust DAT so as to minimize the variation between the level 2 and the level 3 of TP111.

2. Adjust VR5 so that the blue level 4 is at 1.0 Vp-p.

3. Set the input to NTSC, and confirm that the blue level 4 is at

1.0 ± 0.1 Vp-p.
