Item to be Checked
Check that the MUTE1 signal becomes H
after loading is completed.
Check the SPDLFG signal.
Check that the FEDRV signal fluctuates
with 1.65 V at the center.
Check that an S-shaped signal is output
when a waveform of the FE (FEDRV)
signal is rising after it drops down from
1.65 V.
If the symptom persists after the above
corrections.
Item to be Checked
Check that focusing is in. (If focusing is
out, tracking close is not possible.)
With a CD, check that the E and F signals
fluctuate with 2.2 V at the center.
With a DVD, check the A, B, C, and D
signals.
Check that the TE signal fluctuates
with 1.65 V at the center.
Check that the TEDRV signal fluctuates
with 1.65 V at the center, and that a
pulselike signal is output during tracking
close.
If the symptom persists after the above
corrections.
Item to be Checked
Enter Service mode,
"[3] Various displayed information"_
In 3 "Auto device diagnosis",
Check whether be indicated with
"DRIVE OK ".

Corrective Action
DRIVER IC (IC7001) and SODC (IC7006) may
be improperly soldered or defective.
Resolder them, if necessary. If the symptom
persists, replace SODC (IC7006).
SPDLFG signal may be improperly solded and
SODC (IC7006) may be defective.
Resolder them, if necessary. If the symptom
persists, replace SODC (IC7006). If the symptom
persists, replace DRIVER IC (IC7001).
FEDRV signal may be improperly solded and
SODC (IC7006) may be defective.
Resolder them, if necessary. If the symptom
persists, replace SODC (IC7006). If the symptom
persists, replace FEP (IC7002).
FE signal may be improperly solded and SODC
(IC7006) may be defective.
Resolder them, if necessary. If the symptom
persists, replace SODC (IC7006). If the symptom
persists, replace FEP (IC7002).
Replace the parts in the order of
(1) FEP (IC7002), (2) SODC (IC7006),
(3) DRIVER IC (IC7001), (4) SRVB Assy,
then (5) traverse mecha.
Corrective Action
See "In-focus not possible" above.
Check that the signals fluctuate with 2.2 V at the center.
If a DC signal is not output, check the VREF1. If a DC
signal is not output from it, replace the FEP (IC7002).
If an AC signal is not output, check the soldering at the
CN7001–IC7002 of the pickup. If soldering is improper,
resolder it. If soldering is OK, replace the traverse
mecha.
Check the connection of the parts at the periphery of
the FEP (IC7002). If soldering is improper, resolder it.
If soldering is OK, replace the FEP (IC7002).
If the output signal waveform is not proper, the connection
of the SODC (IC7006) and its periphery may be
loose or the parts may be defective. If the connection is
loose, reconnect securely. If the connection is OK,
replace the SODC (IC7006).
Replace the parts in the order of (1) FEP (IC7002),
(2) SODC (IC7006), (3) DRIVER IC (IC7001),
(4) SRVB Assy, then (5) traverse mecha.
Corrective Action
If it is judged as NG, the ATAPI drive does not
work properly. If the track data are not output
although loading and rotating are properly
performed, see "[7] ATAPI DRIVE."
In other cases, see "[8] DRIVE ASSY."
