ELECTRICAL ADJUSTMENTS
Note:
1. VIDEO board 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]
LUV-P01 (CD)
LUV-P01 (CD)
: PART No. 4-999-032-01
TDV-520CSO (DVD-SL) : PART No. J-2501-236-A
TDV-540C (DVD-DL)
TDV-540C (DVD-DL)
: PART No. J-2501-235-A
Note:
Do not use exiting test disc for DVD.
3. Use an oscilloscope with more than 10 M
Ω 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.
AUTO SERVO ADJUSTMENT
After parts related to the servo circuit (RF amplifier (IC001), DSP
(IC1025), motor driver (IC1024), EEPROM (IC1028) so on) are
replaced, re-adjusting the servo circuit is necessary. Select “ALL”
at “1. DRIVE AUTO ADJUSTMENT” (Refer to page 22 in TEST
MODE) and adjust DVD-SL (single layer), CD and DVD-DL (dual
layer).

ADJUSTMENT OF VIDEO SYSTEM
1. Video Level Adjustment (MB Board)
<Purpose>
This adjustment is made to satisfy the NTSC standard, and if not
adjusted correctly, the brightness will be too large or small.
