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 par-

allel, adjust the height of supply side and take-up side guide roller so that the envelope waveform changes nearly parallel. (For envelop adjustment procedure refer to Figure 4-35.)

9 Turn the tilt screw to remove the tape crease at the

fixing guide flange.

Playback 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 envelop 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.

Figure 4-32.

2. Adjustment of A/C head height and azimuth 1 Perform the initial setting of A/C head position by the

method stated in "Page 18 Replacement 3".

2 Connect the oscilloscope to the audio output termi-

nal.

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 Repeat the above adjustment steps 3 and 4 a

couple of times. Finally take the step 4 again.

For X value adjustment Adjust the X value, turning the geartype screwdriver.

Figure 4-33.

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

output test point, set oscilloscope sync to EXT, trigger-input the PB CHROMA signal (head switching pulse).

2 Rough adjustment of X value

Tentatively fix A/C head arm screws 1 and 2 by the method described in Page 18 "Replacement 3". Playback the alignment tape (VROCPSV) and shortcircuit TP802. 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 4-33, 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 envelop waveform is obtained nearest the position of initial setting made in Page 18.)

VC-TA350/TA351/351W VC-TA352W/TA355/TA356

3 Next, 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 take-up side guide roller with the adjustment driver (JiGDRiVERH-4) so that the envelope waveform changes nearly parallel.

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

surface, the PB CHROMA envelope waveform appears as shown in Figure 4-35.

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

the envelope waveform changes nearly parallel.

5. ELECTRICAL ADJUSTMENT

Notes:

• Before the adjustment:

Electrical adjustments discussed 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:

Colour TV monitor Dual-trace oscilloscope

Alignment tape (VROCPSV), (VROATSV)

Blank video cassette tape DC voltmeter Screwdriver for adjustment

Servicing precautions When the IC710 (E2PROM) has been replaced, make the following reprogramming. Depending on models, the IC710 (E2PROM) has been factory-adjusted for it’s memory function. It’s therefore necessary to reprogram the memory function for the model in question. Note that the servo circuit requires readjustments for the head switching point, slow and still modes.

REPLACEMENT OF IC710(E2PROM)

Servicing precautions When the IC710(E2PROM) has been replaced, make the following reprogramming. Depending on models, the IC710(E2PROM) has been factory adjusted for it’s memory function. It’s therefor necessary to reprogram the memory function for the model in question. Note that the servo circuit requires readjustments for the slow and still modes.

1. Memory function reprogramming.

1. Check the power off.(Power is standby mode)

2. Make for moment short-circuit test point (TP801), located at the front side on the main PWB.” Be sure that all the fluorescent display tube light up into the TEST mode.

3. Using the CHANNEL(+) AND (-) buttons, select the right function numbers from JP0ü`J39, which appear in the fluorescent display tube, referring to the E2PROM map. Press the DISPLAY button to pickup the functions (ON) and the CLEAR button to discard the functions(OFF). DISPLAY and CLEAR buttons, are located on the remote control unit.

∗ when the DISPLAY button has been pressed (ON), the memory function number starts flashing. ∗ when the CLEAR button has been pressed (OFF), the memory function number lights up.

4. Press the FF button on the remote control unit. By doing, lower 5 of the 10 digits are displayed in hexadecimal notation. Example : "ON" and "OFF" are taken as "1" and "0" respectively.
