AUTO SERVO ADJUSTMENT
After parts related to the servo circuit (RF amplifier (IC001), DSP
(IC509), motor driver (IC501), EEPROM (IC903) so on) are re-
placed, 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 DVD-DL (dual
layer).

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 sig-
nal 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.
Note:
A clear RF signal waveform means that the shape “
