COMPACT DISC RECEIVER

MICROFILM
Laser component in this product is capable of emitting radiation exceeding the limit for Class 1. This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. This caution label is located inside the unit.

CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing Keep the temperature of 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 HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT 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 pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. 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 two times.

SECTION 5 TEST MODE

AGING MODE
This unit is equipped with an aging mode. Use this mode for analyzing defects and for checks after completing repairs. After repairs, perform aging 100 times and check that the unit is normal. The aging mode is executed in the following sequence. The aging mode will continue as long as the unit is normal. If the unit becomes abnormal, it will display the state and number of cycles, and operations will stop. (Refer to Table 1.) Sequence of Aging Mode:
Start Sets the CD function and reads the CD TOC. NO
CD TOC OK? YES Pauses first song. OK? YES

SECTION 6 ELECTRICAL ADJUSTMENTS

CD SECTION

Note: 1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10M impedance. 4. Clean the object lens by an applicator with lens cleaning liquid when the signal level is low than specified value with the following checks. 5. Adjust the focus bias adjustment when optical block is replaced. Focus Bias Adjustment Perform this adjustment when the optical pick-up has been replaced or repaired.

Procedure : 1. Connect oscilloscope to test point TP (FEO). 2. Connect between test point TP (FOK) and Ground by lead wire. 3. Turn Power switch on. 4. Put disc (YEDS-18) in and turned Power switch on again and actuate the focus search. (actuate the focus search when disc table is moving in and out.) 5. Check the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 2.4 0.7 Vp-p. S-curve waveform

Procedure: 1. Connect oscilloscope to test point TP (RF). 2. Turned Power switch on. 3. Put disc (YEDS-18) in and playback. 4. Adjust RV101 so that the waveform is clear. (Clear RF signal waveform means that the shape can be clearly distinguished at the center of the waveform.) 5. After adjustment, check the RF signal level. RF signal VOLT/DIV: 200 mV TIME/DIV: 500 nS
