Procedure:
1. Press the

I/1

button to turn the power on, and turn the

[FUNCTION] knob to select 

“DVD” of A/V amplifier (TA-

S9D).

2. Confirm that the S-Y level is 1.0 

± 0.05 Vp-p.

<Purpose>
This checks whether the S-C satisfies the NTSC Standard.  If it is
not correct, the colors will be too dark or light.

Procedure:
1. Press the

button to turn the power on, and turn the

[FUNCTION] knob to select 

“DVD” of A/V amplifier (TA-

2. Confirm that the S-C burst is 286 

± 30 mVp-p (NTSC) or 300

± 100 mVp-p (PAL).

During diagnostic check, the characters and color bars can be seen
only with the NTSC monitor. Therefore, for diagnostic check, use
the monitor that supports both NTSC and PAL modes

1) Color monitor TV
2) Oscilloscope 1 or 2 phenomena, band width over 100 MHz,

with delay mode

3) DVD reference disc

<Purpose>
This adjustment is made to satisfy the NTSC/PAL standard, and if
not adjusted correctly, the brightness will be too large or small.

Adjustment

After parts related to the servo circuit (RF amplifier (IC001), DSP
(IC302), motor driver (IC401), EEPROM (IC101) so on) are re-
placed, re-adjusting the servo circuit is necessary. Select “ALL” at
“DRIVE AUTO ADJUSTMENT” (Refer to page 16 in TEST
MODE) and adjust DVD-SL (single layer), CD and DVD-DL (dual
layer).
