COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB- LISHED BY SONY. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam- aged by heat. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C dur- ing 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. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra- diation exposure. This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. Laser component in this product is capable of emitting radiation exceeding the limit for Class 1. The following caution label is located inside the unit. RadioFans.CN 收音机爱 好者资料库 3 SECTION 1 SERVICING NOTES The laser diode in the optical pick-up block may suffer electro- static break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down 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. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emis- sion, observe from more than 30 cm away from the objective lens. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT 4-221-269- AEP Model: 0 s? Singapore Model: 1 s MODEL IDENTIFICATION BACK PANEL HOW TO PLAY CD WITH THE DISC TRAY OPENED To play a CD by this method, the screws that secure the SERVO board to the chassis must be removed in advance. Procedure: 1.Press!button to turn the power ON. 2.Set a CD on the disc tray. 3.With the disc tray opened, connect pin 1 and pin 2 of CN272 on the LOADING MOTOR board using tweezers, etc. 4.As the disc starts to move toward direction A, intercept the sensor in B section with your finger immediately. (See “HOW TO OPERATE THE SET WITHOUT USING STABILIZER” on page 5) 5.You can release your hand when TOC is read. 6.Hence, the operation equivalent to normal operation can be performed. short here A B 4 DISC PULLEY INSTALLING POSITION Note: The shaft on which the disc pulley is installed has a groove to determine the position (height). Install the disc pulley so that a setscrew can settle in this groove. set screw (M2.6 4) set screw groove groove disc pulley disc pulley HOW TO OPEN DISC TRAY WHEN POWER IS OFF Insert a flat-blade screwdriver into a hole at the bottom of the set, and rotate the pulley in the arrow direction to open the disc tray. IN disc tray flat-blade screwdriver OUT 5 SERVICE POSITION OF SERVO BOARD In servicing the SERVO board, erect the board as shown below. In this case, the CN201 and CN202 connectors are disconnected respectively, and accordingly the buttons on the front panel do not function. Therefore, use the Remote Commander for fundamental operations such as PLAY and STOP. Also, in performing the service under this condition, the stabilizer is not detected, so refer to “How to Operate the Set without Using Stabilizer”. disconnect CN201 disconnect CN202 SERVO board HOW TO OPERATE THE SET WITHOUT USING STABILIZER As this set detects the stabilizer, if servicing the set in other than normal operating way, disable the stabilizer detecting function by the following method. The stabilizer is detected before TOC is read, and after that, this function does not operate. That is, the stabilizer detection is executed after power on or immediately after disc loading, and you can release your finger after the disc was recognized. Intercept the D202 on SERVO board with your finger. 6 SECTION 2 GENERAL 123450 qaqs 7689 qkql qdqfqgqhqj w;wa 1!
