ELECTRICAL ADJUSTMENT
[TEST DISC LIST]
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
Note: Do not use exiting test disc for DVD.
AUTO SERVO ADJUSTMENT
After parts related to the servo circuit (RF amplifier (IC001), DSP
(IC401), motor driver (IC501), EEPROM (IC302) so on) are
replaced, re-adjusting the servo circuit is necessary. Select “ALL”
at “1. DRIVE AUTO ADJUSTMENT” (Refer to page 29 in TEST
MODE) and adjust DVD-SL (single layer), CD and D VD-DL (dual
layer).

Procedure:
1. Connect an oscilloscope to test point pin 1 and pin 3 of CN901
on the DMB03 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) (D VD) in
to playback.
6. Perform Comfirmation in the same manner as step 4.
Note: A clear RF signal waveform means that the shape “◊” can be clearly
distinguished at the center of the waveform.
