About the dicision to pass or fail of the optical pick-up block, refer
to “DICISION TO PASS OR FAIL OF THE OPTICAL PICK-UP
BLOCK” (Refer to page 6 in SERVICING NOTES)

1. DVD block is basically designed to operate without

adjustment. Therefore, check each item in order given.

2. Use DVD reference disc unless othermise indicated.

[DVD reference disc]
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.

3. Use an oscilloscope with more than 10MW impedance.
4. Clean the object lens by an applicator with neutral detergent

when the signal level is low than specified value with the
following checks.

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 19 in TEST MODE)
and adjust DVD-SL (single layer), CD and DVD-DL (dual layer).

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