After parts related to the servo circuit (RF amplifier (IC102), DSP
(IC201), motor driver (IC101), EEPROM (IC205) so on) are
replaced, re-adjusting the servo circuit is necessary.

Use the following test disc on test mode.
TDV-520CSO (DVD-SL):

PART No. J-2501-236-A

LUV-P01 (CD):

PART No. 4-999-032-01

TDV-540C (DVD-DL):

PART No. J-2501-235-A

Do not use exiting test disc for DVD.

1. Connect an oscilloscope to CN204 pin 6  (RFMON) and

CN204 pin 3 (GND) on the DMB09 board.

2. Turn the power on.
3. Set the test disc (DVD: TDV-520CSO, CD: LUV-P01) on the

tray and press  H   button to playback.

4. Confirm that oscilloscope waveform is clear and check

RFMON signal level is correct or not.

A clear RFMON signal waveform means that the shape “

” can be

clearly distinguished at the center of the waveform.
