SERVICING NOTES
CFD-V3/V7/V7L
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic breakdown and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled
with care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode
emission, observe more than 30 cm away from the objective
lens.
CHUCK PLATE JIG ON REPAIRING
On repairing CD section, playing a disc without the CD lid, use
Chuck Plate Jig.
• Code number of Chuck Plate Jig : X-4918-255-1
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
1. Press CD open knob.
2. Open the lid for CD.
3. Push on SWITCH (S801) as following figure.
4. Confirm the laser diode emission while observing the
objecting lens. When there is no emission, Auto Power
Control circuit or Optical Pick-up is broken.
Objective lens moves up and down once for the focus
search.
Insert a precision
screw driver and push

PRECAUTION
1. Clean the following parts with a denatured-alcohol-moistened
swab :
CD section adjustments are done automatically in this set.
In case of operation check, confirm that focus bias.
Focus Bias Check
1. Connect the oscilloscope between TP (RF) and GND on CD
board.
2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01)
3. Press the 7 button two times (LPC ON).
4. Confirm that the oscilloscope waveform is as shown in the figure below. (eye pattern)
A good eye pattern means that the diamond shape (◊) in the
center of the waveform can be clearly distinguished.

How to put the set into CD Test Mode
1. Set the function switch to power off.
2. Set the function switch to CD.
3. Set Test mode by momentarily shorting both of the IC801 51pin
to GND. (Shorting the terminals momentarily is sufficient).
The set is into CD test mode (88 is displayed).
4. Turn the power off to release test mode.
