12、ircuit Board Repairing Keep the temperature of the soldering iron around 270C 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 Replaceme

13、nt Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. TABLE OF CONTENTS 1. SERVICE NOTE. 2 2. GENERAL. 4 3.

SECTION 1 SERVICE NOTE NOTE ON PERFORMING SERVICE AND INSPECTION ON THE MAIN BOARD The main board has two types, former type and new type. When performing service and inspection, check the

20、 part number on the main board. MAIN BOARD (SIDE A) MAIN Board Part No. Former type : 1-680-271-11 New type : 1-681-329-11 收音机爱 好者资料库 RadioFans.CN 3 NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electro- static breakdown because of t

21、he 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

22、 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

23、 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 “Opti- cal Pick-Up Block Checking Procedures” (Part No.: 9-960-027- 11) issued separately before replacing the optical pick-up block. Note and specifications

24、 required to check are given below. FOK output : IC601 eg 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 i

25、s 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.With a disc not set, turn on the S801 with a screwdriver hav

26、ing 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 button. 4.Observing the objective lens, check that the laser diode emits light. When the laser diode does not emit light, automatic po

27、wer 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.
