IMPORTANT SERVICE NOTES

Maintenance and repair of this receiver should be done by qualified service personnel only.

SERVICING OF HIGH VOLTAGE SYSTEM AND PICTURE TUBE

When servicing the high voltage system, remove static charge fr om it by connecting a 10k ohm Resistor in series with an insulated wire (such as a test probe) between picture tube dag and 2nd anode lead. (A C line cord should be disconnected from AC outlet.)

1. Picture tube in this receiver employs integral implosion protection.

2. Replace with tube of the same type number for continued safety.

3. Do not lift picture tube by the neck.

4. Handle the picture tube only when wearing shatterproof goggles and after discharging the high voltage completely.

37VT-26H(GY)

X-RAY

This receiver is designed so that any X-Ray radiation is kept to an absolute minimum. Since cer tain malfunctions or servicing may produce potentially hazardous radiation with prolonged exposure at close range, the following precautions should be observed:

1. When repairing the circuit, be sure not to increase the high voltage to more than 25.3 kV, (at beam 0 µA) for the set.

2. T o keep the set in a normal operation, be sure to make it function on 22.0 kV + 1.5 kV – 2.0 kV (at beam 800 µA) in the case of the set. The set has been factory – Adjusted to the above-mentioned high voltage. ∴ If there is a possibility that the high voltage fluctuates as a result of the repair s, never

forget to check for such high voltage after the work.

3. Do not substitute a picture tube with unauthorized types and/or brands which may cause excess X-ray radiation.

BEFORE RETURNING THE RECEIVER

Before returning the receiver to the user , perform the following saf ety checks.

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

18. ADJUSTMENT OF TAPE DRIVE TRAIN

1. Tape run rough adjustment

1 Remove the cassette housing control assembly. 2 After shortcircuiting TP7701 (J930) and TP7702

(J359) provided at the left on the main PWB, plug in the power cord, then turn on the power.

3 Check and adjust the position of the tension pole.

(See 12..)

4 Check and adjust the video search rewind back

tension. (See 10..)

5 Connect the oscilloscope to the test point for PB

CHROMA envelope output (TP3301). Set the synchronism of the oscilloscope to EXT. The PB CHROMA signal is to be triggered by the head switching pulse (TP3302).

6 After turnning off the power, set the alignment

tape (VROCPSV) then turn on the power and playback the tape. (Put a 500g weight on the cassette tape to prevent lift of cassette tape.)

1 Perform the initial setting of A/C head position by

the method stated in "15. Replacement -3.".

2 Connect the oscilloscope to the audio output

(TP6601).

3 Using the alignment tape in which 1 kHz linear

audio signal has been recorded, adjust the height screw so as to get max audio output.

4 Using the alignment tape in which 6 kHz linear

audio signal has been recorded, adjust the azimuth screw so as to get max audio output.

5 The adjustment of 3 and 4 twice or three times

repeat, and finally adjust 4.

7 Press the tracking button (+), (–) and change the

envelope waveform from max to min and from min to max. At this time make sure that the envelope waveform changes nearly parallel.

8 Unless the envelope waveform changes nearly

parallel, adjust the height of supply side and takeup side guide roller so that the envelope waveform changes nearly parallel. (For envelop adjustment procedure refer to Figure 1-35.)

9 Turn the tilt screw to remove the tape crease at

the fixing guide flange. Play back the tape and check for tape crease at the fixing guide flange. (1)If there is no tape crease

Turn the tilt screw clockwise so that tape crease appears once at the flange, and then return the tilt screw so that the crease disappears.

(2)If there is tape crease

Turn counterclockwise the tilt screw so that the tape crease disappears. (Reference) If the tilt screw is turned clockwise crease appears at the lower flange.

Notes:

1. Previously set the tracking control in the center position, and adjust the envelope waveform to maximum with X value adjustment nut. Thereby the tape run rough adjustment is facilitated.

2. Especially the outlet side envelope waveform must have higher flatness.

For X value adjustment Adjust the X value, turning the gear driver.

Figure 1-33.

3. Tape run adjustment 1 Connect the oscilloscope to PB CHROMA enve-

lope output test point (TP3301), set oscilloscope sync to EXT, trigger-input the head switching pulse (TP3302).

2 Rough adjustment of X value

Tentatively fix A/C head arm screws 1 and 2 by the method described in 15. "Replacement -3.". After shortcircuiting TP7701 (J930) and TP7702 (J359), plug in the power cord, turn off the power, set the alignment tape (VROCPSV), turn on the power and then playback the tape. As a result the auto-tracking is automatically cancelled, so that the X value adjustment mode is set. Move the A/C head with the X value adjustment gear driver (JiGDRiVER-6) by the method shown in Figure 1-33, and adjust the A/C head so as to get the maximum envelope waveform. (Note: When the A/C head is adjusted, adjust so that the maximum envelope waveform is obtained nearest the position of initial setting made in 15..)

3 When the VROCPSV tape is used, press the

tracking button (+), (–) and change the envelope waveform from max to min and from min to max. At this time adjust the height of supply and takeup side guide roller with the adjustment driver (JiGDRiVERH-4) so that the envelope waveform changes nearly parallel.

Page 34

37VT-26H(GY)

4 If the tape is lifted or sunk from the helical lead

surface, the PB CHROMA envelope waveform appears as shown in Figure 1-35.

5 Press the tracking button (+), (–) and make sure

that the envelope waveform changes nearly parallel.

6 Finally check tape crease near the reverse guide.

If tape crease is found, remove it as stated in 17. "HEIGHT ADJUSTMENT OF REVERSE GUIDE" item 3.

When the tape is above the helical lead. When the tape is below the helicallead.

4. A/C head X value adjustment 1 Tentatively fix A/C head arm screws 1 and 2 by

the method described in 15. "Replacement -3.".

2 After shortcircuiting TP7701 (J930) and TP7702

(J359), plug in the power cord, turn off the power, set the alignment tape (VROCPSV), turn on the power and then playback the tape. As a result the auto-tracking is automatically cancelled, so that the X value adjustment mode is set.

3 Move the A/C head with the X value adjustment

gear driver by the method shown in Figure 1-33, and adjust the A/C head so as to get the maximum envelope waveform. (Note: At this time adjust so as to get the maximum envelope waveform nearest the A/C head position which has been set in case of X value rough adjustment as stated in 18., 3-2).

4 Tighten finally the screws 1 and 2. Be sure to

tighten at first the screw 1 and then the screw 2. Final tightening torque is 0.6N·m (If the screw 2 is tightened first, the X value may deviate.)

Take-up side guide roller rotated in clockwise direction (lowers guide roller) to flatten envelope.

Figure 1-35.

5 Adjust the playback switching point (Refer to the

electric adjustment method.)

6 Playback the self-picture-recorded tape, and

check the flatness of envelope waveform and sound.

Note:

When the A/C head X value adjustment is performed, be sure to perform at first X value rough adjustment (refer to 18., 3-2).

Supply side guide roller rotated in counterclockwise direction (raises guide roller) to make the tape float above the helical lead. The supply side guide roller is then rotated in the clockwise direction to flatten the envelope.

Figure 1-36.

Take-up side guide roller rotated in counterclockwise direction (raises guide roller) to make the tape float above the helical lead. The take-up side guide roller is then rotated in the clockwise direction to flatten the envelope.

ADJUSTMENT OF THE VCR ELECTRICAL CIRCUITRY

Notes:

» Before the adjustment:

Electrical adjustments described here are often required after replacement of electronic components and mechanical parts such as video heads. Check that the mechanism and all electric components are in good working condition prior to the adjustments, otherwise adjustments can not be completed.

» Instruments required:

Dual-trace oscilloscope Blank video cassette tape Colour bar generator Alignment tape (VROCBZF)

» Adjustment of the VCR should be done in the TV/VCR combinated style. But there is a function that is able

to cut off high voltage of TV. Namely, you can check only VCR part by taking the plug of P2002 off the socket SC2002 in Main PWB (PWB-A). Therefore you can use this function on the occasion of checking and adjustment of VCR part.
