Connection:
Procedure:
1. Connect an oscilloscope to CN1105 pin 6 (RFMON) and
CN1105 pin 3 (GND) on the MAIN board.
2. Turn the power on.
3. Insert the CD test disc (refer to the TEST DISC LIST), and
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 disc (refer to
the TEST DISC LIST), and press the H button to play the
disc back.
