If the problem is not resolved. The DRIVER ICs (IC100/900) are defective;
replace them.

Check if the FFC that connect the
Pickup and SRV1/2 Assys are
securely connected and if there is
breakage in the Cables.
If a connection is loose, firmly connect the
cables.
If there is breakage, replace the Cables.

Check the mounting status of the
following resistors :
R104-R107 (SRV 1)/R904-R907
(SRV 2) and R108-R111 (SRV
1)/R908-R911 (SRV 2).
If any resistor is improperly mounted, resolder
it.

If there is no signal, check the mounting status
of the DRIVER IC and SODC (IC106/906). If
they are properly mounted, the SODC
(IC106/906) are defective; replace them.

If there is no signal, check the mounting status
of the DRIVER IC (IC100/900) and SODC
(IC106/906). If they are properly mounted, the
SODC (IC106/906) are defective; replace
them.

Check if the SPIN signal input to
Pins 29 and 26 of IC100/900 is
3.3 V at full speed.

If no signal is input, check the mounting status
of R133/R933 resistors and C1160/C1960
capacitor. If they are not properly mounted,
resolder them.

Check the following voltages :
OEIC5V, VAC, VHAF, and
VLEFV.
If OEIC5V is not output, check the mounting
status of the regulator IC that regulates the
corresponding voltage and its peripheral
devices. If they are properly mounted, then the
regulator IC is defective; replace it.
Other power (VAC, VHAF, and VLEFV) is
generated at the FEP (IC102/902). If these
voltages are not output, check the mounting
status of the FEP. If they are properly
mounted, they are defective; replace them.
