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 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.
SAFETY CHECK-OUT
After correcting the original service problem, perform the follow­ing safety check before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. 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. Follo w 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 low­voltage 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 A C range are suit­able. (See Fig. A)
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra­diation exposure.
This label is located on the LEFT exterior.

SERVICING NOTES

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 pick-up block. Therefore, when checking the laser diode emis­sion, observe from more than 30 cm away from the objectiv e lens.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveforms is output three times.
CLEANING OF OPTICAL PICK-UP LENS
In cleaning the lens of optical pick-up, use the air blower. Never use a cotton swab for cleaning the lens of optical pick-up, which otherwise causes a trouble.
HOW TO OPEN THE DISC TABLE WHEN PO WER SWITCH TURNS OFF
Insert a tapering driver into the aperture of the unit bottom, and turn it in the direction of the arrow (to OUT direction).
