Flexible Circuit Board Repairing
Keep the temperature of the soldering iron around 270°C during repairing.
Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering or unsoldering.
Notes on Chip Component Replacement
Never reuse a disconnected chip component.
Notice that the minus side of a tantalum capacitor may be
damaged by heat.

SERVICE NOTE

D-F200/F201
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro­static breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body . During repair, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care.
Precautions for Checking Emission of Laser Diode
Laser light of the equipment is focused by the object lens in the optical pick-up so that the light focuses on the reflection surface of the disc. Therefore, be sure to keep your eyes more then 30 cm apart from the object lens when you check the emission of laser diode.
Before Replacing the Optical Pick-Up Block
Please be sure to check throughly the parameters as par the “Opti­cal Pick-Up Block Checking Procedures” (Part No.: 9-960-027-
11) issued separately before replacing the optical pick-up block. Note and specifications required to check are given below.
• FOK output : IC601 yg pin When checking FOK, remove the lead wire to disc motor.
• RF signal P-to-P value : 0.45 ± 0.1 Vp-p
• The repairing grating holder is impossible.
Laser Diode Checking Methods
During normal operation of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning ON the S801. (push switch type) The following two checking methods for the laser diode are operable.
• Method: Emission of the laser diode is visually checked.
1. Open the upper lid.
2. W ith a disc not set, turn on the S801 with a scre wdri ver having a
thin tip as shown in Fig.1. or TAP802 is shorted as shown in Fig.2. Note: Do not push the detection lever strongly , or it may be bent
or damaged.
3. Press the N X button.
4. Observing the objective lens, check that the laser diode emits
light. When the laser diode does not emit light, automatic power control circuit or optical pick-up is faulty. In this operation, the objective lens will move up and down 5 times along with inward motion for the focus search.
