D-F200/F201 SECTION 1 SERVICE NOTE
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.: 9-960-02711) 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.

operable. � Method: Emission of the laser diode is visually checked. 1. Open the upper lid. 2. With a disc not set, turn on the S801 with a screwdriver 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.
