ELECTRICAL PARTS LIST ............................... 40 Flexible Circuit Board Repairing - Keep the temperature of the soldering iron around 270 ËšC 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. 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.

3 3 SECTION 1 SERVICING NOTES 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 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. 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. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra- diation exposure. DISC MAGAZINE GETTING OUT PROCEDURE ON THE POWER SUPPLY IS OFF Remove the COVER (LOWER T) beforehand 1) Press the lever (ML.S) assy in the direction of arrow A. 2) Removal the magazine assy. Note: Take out the magazine only when the tray is completely within the magazine. If the disk or tray is sticking out, turn on the power and eject the magazine. Lever (ML.S) Magazine assy A SECTION 2 GENERAL This section is extracted from instruction manual. Ver 1.1 2000. 08 If the optical pick-up block is defective, please replace the whole optical pick-up block. Never turn the semi-fixed resistor located at the side of optical pick-up block.
