– SUMMARY
This service manual covers only the different points from the service manual, file no. 810-9807, for model SD-9000 since SD-9100 are basically the same designing as SD-9000. Please refer to the file no. 810-9807 for other information.

LASER BEAM CAUTION LABEL
VISIBLE LASER RADIATION
CAUTION
WHEN OPEN AND INTERLOCK DEFEATED DO NOT STARE INTO BEAM.
WAVE LENGTH:650nm, MAX.LASER POWER:0.45mW
98763036
When the power supply is being turned on, you may not remove this laser cautions label. If it removes, radiation of a laser may be recceived.
PREPARATION OF SERVICING
Pickup Head consists of a laser diode that is very susceptible to external static electricity. Although it operates properly after replacement, if it was subject to electrostatic discharge during replacement, its
life might be shortened. When replacing, use a conductive mat, soldering iron with ground wire, etc. to protect the laser diode from damage by static electricity.
And also, the LSI and IC are same as above.
Ground conductive wrist strap for body.
Soldering iron with ground wire or ceramic type
1M
Conductive mat
The ground resistance between the ground line and the ground is less than 10.

• The waveforms for CD/DVD and RF shown in the circuit diagrams are obtained when a test disc is played back.
• All voltage values except the waveforms are expressed in DC and measured by a digital voltmeter.
1-6. Others
• The parts marked with “NC” or “KETU” in the circuit diagrams are not used for this model.
