SECTION 5
ELECTRICAL ADJUSTMENTS
Procedure:
1. Connect an oscilloscope to RF pin and GND pin on the special
jig (J-2501-272-A).
2. Press the
I
/1
button tourn the power on.
3. Insert the test disc (DVD: TDV-520CSO, CD: LUV-P01) on
the set and touch the
u
sensor on the touch panel to playback.
4. Confirm that oscilloscope waveform is clear and check
RFMON signal level is correct or not.
Note:
A clear RFMON signal waveform means that the shape “
◊” can be
clearly distinguished at the center of the waveform.
DVD SECTION
AUTO SERVO ADJUSTMENT
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 27 in TEST
MODE) and adjust DVD-SL (single layer), CD and DVD-DL (dual
layer).
