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
Check the MAIN DSP (IC301,) using
automatic device diagnostics and the
status LEDs.
Item to be Checked
—————
Check the power voltages (V+3R3_DSP
and V+1R2_DSP).
Check that the frequency at Pin 38 (DSP_
CLK) of SD_RAM (IC302) is
approx. 129 MHz.
Check that the signals of the DSP_RST
and CPU_DSP_RST lines are H.
Check the connection between the
MAIN CPU and MAIN DSP.
Check the connection between the
MAIN DSP and SD_RAM.
If the symptom persists after the above
corrections.

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 [6] ATAPI DRIVE. In other cases,
see [9] DRIVE ASSY.
Corrective Action
If it is judged as NG, the MAIN DSP (IC302) does
not work properly or communication between the
MAIN CPU (IC10) and MAIN DSP is not
established. Proceed as follows:
The MAIN DSP requires two power supply systems.
Check the connections of the power supply lines.
If soldering is improper, resolder it.
Check the connection of the logic ICs
(IC16, 506).
If soldering is improper, resolder it.
Check the connection of the logic IC (IC8).
If soldering is improper, resolder it.
If the signal of the CPU_DSP_RST line is L, the
port on the MAIN CPU may be damaged.
If the signal of the DSP_RST line is L, check the
connection of the logic IC (IC8) and its periphery.
Check the connections between MAIN CPU
(IC10) and MAIN DSP (IC301).
If soldering is improper, resolder it.
Check the connections between MAIN DSP
(IC301) and SD_RAM (IC302).
If soldering is improper, resolder it.
Replace the MAIN Assy.
