6、el: 4 Singapore Model: 5 Austrarian Model: 6 CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra- diation exposure. The laser component in this product is capable of emitting radiation exceeding the limit for Class 1. This

7、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. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may

8、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. 4-982-7

11、HOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. SAFETY CHECK-OUT (US model only) After correcting the original service problem, perform the follow- ing safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other

12、exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE 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 microampers). Leak- age current can be measured

13、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 dro

14、p 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 pas- sive VOM that is suitable. Nearly all battery operated digital multimeters tha

15、t have a 2V AC range are suitable. (See Fig. A) NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human bod

16、y. 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

17、 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. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section

18、 adjustment” and check that the S curve waveform is output repeatedly. SECTION 1 SERVICING NOTE Fig. A. Using an AC voltmeter to check AC leakage.

Note: To exit this mode, press the POWER button. 4-2. ADJ Mode 1. Turn ON the power of the unit, set disc to disc

25、table, and perform chucking. 2. Disconnect the power supply plug from the outlet. 3. To set ADJ mode, connect the test point (TP301:ADJ) of the MAIN board to Ground, and turn on the power supply plug to the outlet. The power will turn on automatically, and the first track will be played. In this mod

26、e, table rotation and loading operations are not performed because it is taken that the disc has already been chucked. Note: The same operations are also performed in the following when the test point (TP301:ADJ) is connected to Ground after turn- ing on the power. Direct search (movement of sleddin
