SAFETY CHECK-OUT(US model only)
After correcting the original service problem, perform thefollowing safety checks 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 asdescribed below.
LEAKAGE
The AC leakage from any exposed metal part to earth groundand from all exposed metal parts to any exposed metal part havinga return to chassis, must not exceed 0.5 mA (500 microampers).Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCAWT-540A. Follow the manufacturers’ instructions to use theseinstruments.
2. A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit” indicationis 0.75 V, so analog meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa SH-63Trd are examples ofa passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)

SERVICING NOTES
The laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused onthe disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission, observefrom more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATIONCHECK
Carry out the “S curve check” in “CD section adjustment” and checkthat the S curve waveform is output repeatedly.
NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT
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.
