Procedure:
1. Mode:  Playback

2. Turn the adjustment screw and check output peaks. If the peaks

do not match for L-CH and R-CH, turn the adjustment screw so
that outputs match within 1dB of peak.

1. Demagnetize the record/playback head with a head

demagnetizer.

2. Do not use a magnetized screwdriver for the adjustments.
3. After the adjustments, apply suitable locking compound to the

parts adjust.

4. The adjustments should be performed with the rated power

supply voltage unless otherwise noted.

5. The adjustments should be performed in the order given in this

service manual.  (As a general rule, playback circuit adjustment
should be completed before performing recording circuit
adjustment.)

6. The adjustments should be performed for both L-CH and R-

CH.

7. Switches and controls should be set as follows unless otherwise

specified.

• Test Tape

1. Clean the following parts with a denatured alcohol-moistened

swab:

record/playback heads

pinch rollers

2. Demagnetize the record/playback head with a head

demagnetizer.

3. Do not use a magnetized screwdriver for the adjustments.
4. After the adjustments, apply suitable locking compound to the

parts adjusted.

5. The adjustments should be performed with the rated power

Procedure:
In the MC test mode, the “REC memory mode” is convenient for
this adjustment. In the “REC memory mode” , when the REC starts
the input signal FUNCTION is switched to VIDEO automatically.
When the REC stops, the tape returns near to the recording start
position.

After parts related to the servo circuit (RF amplifier (IC001), DSP
(IC509), motor driver (IC501), EEPROM (IC903) so on) are
replaced, re-adjusting the servo circuit is necessary. Select “ALL”
at  “1. DRIVE AUTO ADJUSTMENT” (Refer to page 28 in TEST
MODE) and adjust DVD-SL (single layer), CD and DVD-DL (dual
layer).

Procedure:
1.

Connect an oscilloscope to test point 1  pin and 3  pin of
CN901 on the MB board.

2.

Turn the power on.

3.

Put the disc (LUV-P01) (Part No.: 4-999-032-01) (CD) in to
playback.

4.

Confirm that oscilloscope waveform is clear and check RF
signal level is correct or not.

5.

Put the disc (TDV-520CSO) (Part No.: J-2501-236-A) (DVD)
in to playback.

6.

Perform confirmation in the same manner as step 4.

A clear RF signal waveform means that the shape “

◊” can be clearly

distinguished at the center of the waveform.
