HCD-FX100W
Procedure:
1. Terminate the COMPONENT VIDEO OUT (Y) connector in
75
Ω
.
2. Connect an oscilloscope across 75
Ω
terminator.
3. Turn the power on.
4. Set the test disc (HLX-504) on the tray and press
H
button
to playback.
5. Confirm that oscilloscope waveform is clear and check
component output level is correct or not.
6. If it is not correct, adjust the RV502 to attain 1.0 Vp-p.
Adjustment Location:

When the base unit is replaced, perform the adjustment and the
measurement as shown below in this order.
1) MIRROR TIME ADJUSTMENT (See page 24)
2) EXECUTING IOP MEASUREMENT (See page 26)
Be sure to use the DVD disc that matches the signal standards of

[RF Level Check]
Connection:
Procedure:
1. Conect an oscilloscope to CN105 pin
6
(RFMON) and CN105
pin
3
(GND) on the DMB10 board.
2. Turn the power on.
3. Insert the CD test disc (refer to the TEST DISC LIST), and
press the
H
button to play the disc back.
4. Confirm that oscilloscope waveform is clear and check RF
signal level is correct or not.
Note:
A clear RF signal waveform means that the shape “
◊
” can be
clearly distinguished at the center of the waveform.
5. Eject the CD disc, and insert the DVD SL test disk (refer to the
TEST DISC LIST), and press the
H
button to play the disc
back.
