SAFETY INFORMATION This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician.

A

- Safety Precautions for those who Service this Unit. • When checking or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable results.

B

Caution: 1. During repair or tests, minimum distance of 13 cm from the focus lens must be kept. 2. During repair or tests, do not view laser beam for 10 seconds or longer.

CAUTION: USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

C

CLASS 1 LASER PRODUCT

D

WARNING! The AEL (accessible emission level )of the laser power output is less than CLASS 1 but the laser component is capable of emitting radiation exceeding the limit for CLASS 1. A specially instructed person should do servicing operation of the apparatus. E

Laser diode characteristics Wave length : 785 nm to 814 nm Maximum output : 1 190 µW(Emitting period : unlimited)

Additional Laser Caution Transistors Q101 in PCB drive the laser diodes. When Q101 is shorted between their terminals, the laser diodes will radiate beam. If the top cover is removed with no disc loaded while such short-circuit is continued, the naked eyes may be exposed to the laser beam.

- Service Precaution 1. You should conform to the regulations governing the product (safety, radio and noise, and other regulations), and should keep the safety during servicing by following the safety instructions described in this manual. 2. Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors during power-on mode may damage the ICs inside the unit. 3. To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment (shorting-solder) by referring to "the DISASSEMBLY". 4. After replacing the pickup unit, be sure to check the grating. 5. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic induction.

[Important Check Points for Good Servicing] In this manual, procedures that must be performed during repairs are marked with the below symbol. Please be sure to confirm and follow these procedures. A

1. Product safety Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by following the safety instructions described in this manual. 1 Use specified parts for repair. Use genuine parts. Be sure to use important parts for safety. 2 Do not perform modifications without proper instructions. Please follow the specified safety methods when modification(addition/change of parts) is required due to interferences such as radio/TV interference and foreign noise. 3 Make sure the soldering of repaired locations is properly performed.

B

When you solder while repairing, please be sure that there are no cold solder and other debris. Soldering should be finished with the proper quantity. (Refer to the example) 4 Make sure the screws are tightly fastened. Please be sure that all screws are fastened, and that there are no loose screws. 5 Make sure each connectors are correctly inserted. Please be sure that all connectors are inserted, and that there are no imperfect insertion. 6 Make sure the wiring cables are set to their original state. Please replace the wiring and cables to the original state after repairs. In addition, be sure that there are no pinched wires, etc.

C

7 Make sure screws and soldering scraps do not remain inside the product. Please check that neither solder debris nor screws remain inside the product. 8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord. Damaged power cords may lead to fire accidents, so please be sure that there are no damages. If you find a damaged power cord, please exchange it with a suitable one. 9 There should be no spark traces or similar marks on the power plug. When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary. 0 Safe environment should be secured during servicing.

D

When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely.

2. Adjustments To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification. Adjustments should be performed in accordance with the procedures/instructions described in this manual.

3. Lubricants, Glues, and Replacement parts Use grease and adhesives that are equal to the specified substance. Make sure the proper amount is applied.

E

4. Cleaning For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper cleaning should be performed to restore their performances.

5. Shipping mode and Shipping screws To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be installed before shipment. Please be sure to follow this method especially if it is specified in this manual.

6. ADJUSTMENT 6.1 CD ADJUSTMENT A

1) Cautions on adjustments • In this product the single voltage (3.3 V) is used for the regulator. The reference voltage is the REFO1 (1.65 V) instead of the GND. If you should mistakenly short the REFO1 with the GND during adjustment, accurate voltage will not be obtained, and the servo’s misoperation will apply excessive shock to the pickup. To avoid such problems: a. Do not mix up the REFO1 with the GND when connecting the (-) probe of measuring instruments. Especially on an oscilloscope, avoid connecting the (-) probe for CH1 to the GND. b. In many cases, measuring instruments have the same potential as that for the (-) probe. Be sure to set the measuring instruments to the floating state. c. If you have mistakenly connected the REFO1 to the GND, turn off the regulator or the power immediately. • Before mounting and removing filters or leads for adjustment, be sure to turn off the regulator. • For stable circuit operation, keep the mechanism operating for about one minute or more after the regulator is turned on.

2) Test mode This mode is used to adjust the CD mechanism module. • To enter the test mode. While pressing the 4 and 6 keys at the same time, reset. • To exit from the test mode. Turn off the ACC and back up. Notes: a. During ejection, do not press any other keys than the EJECT key until the loaded disc is ejected. b. If you have pressed the (→) key or (←) key during focus search, turn off the power immediately to protect the actuator from damage caused by the lens stuck. c. For the TR jump modes except 100TR, the track jump operation will continue even if the key is released. d. For the CRG move and 100TR jump modes, the tracking loop will be closed at the same time when the key is released. e. When the power is turned off and on, the jump mode is reset to the single TR (91), the RF amp gain is set to 0 dB, and the auto-adjustment values are reset to the default settings.

B

C

• In the test mode, any software protections will not work. Avoid applying any mechanical or electrical shock to the mechanism during adjustment. • The RFI and RFO signals with a wide frequency range are easy to oscillate. When observing the signals, insert a resistor of 1k ohms in series. • The load and eject operation is not guarantied with the mechanism upside down. If the mechanism is blocked due to mistaken eject operation, reset the product or turn off and on the ACC to restore it.
