Notice that the minus side of a tantalum capacitor may be damaged by heat. 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. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. This appliance is classified as a CLASS 1 LASER product This label is located on the rear exterior The laser diode in the optical pick-up block may suffer electrostatic 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 emission, observe from more than 30 cm away from the objective lens. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output three times.

Check leakage as described below. LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes.). Leakage current can be measured by any one of three methods. 1.A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers instructions to use these instruments. 2.A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3.Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable.

Setting Methed of Test Mode Press three buttons m , PUSH ENTER and POWER simulta- neously, The test mode becomes active. Then all segments of the fluorecent indicator tube are turned on. 2. FL Tube Grid, Segments Check Procedure: 1.Grid of all segments lights up sequentially starting from 1G to 16G. 2.The vertical line (total 5 lines) of all grids lights up sequentially in the range of 5G to 16 G starting from the left. 3.The horizontal line of (total 7 lines) of all grids lights up sequentially in the range of 5G to 16G starting from the top. 3. Sircs Receive Check Procedure: 1.The message “SIRCS CHECK” is displayed on the fluorecent indicator tube. 2.With the machine in the status that is set in step 2, press any on the remote commander. The machine enters the key check standby state. (When the H key or the x key is pressed, the reception check is canceled.) 4. Key Check Procedure: 1.In the key check mode, the fluorecent indicator displays “KEY CHECK*”. Each time a button is pressed, “*” value. However, once a button is pressed, it is no longer taken into account. 2.To exit from this mode, the message “JOG CHECK” is displayed. 5. Jog Check Procedure: 1. After the key check is completed, turn JOG clockwise to turn on the calendar segments sequentially. When the segment “15” is confirmed, turn JOG counter-clockwise that turns off the calendar segment. When the segment “1” is confirmed, this is the end of check. 6. Releasing Meted of Test Mode 1.After all the checks are completed, confirm to see that the display “TEST-END” appears. The message indicates that the check is ended normally. 2.Press the POWER button to turn off the main power and disconnect the power plug from the wall outlet. 77 SCD-CE595 SCD-CE595 SECTION 4 DIAGRAMS Circuit Boards Location NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS Note on Printed Wiring Board: X : parts extracted from the component side.
