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).

Leakage current can be measured by any one of three methods.

A commercial leakage tester, such as the Simpson 229 or RCA

WT-540A. Follow the manufacturers' instructions to use these

instruments.

A battery-operated AC milliammeter. The Data Precision 245

digital multimeter is suitable for this job.

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 2V AC 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.

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 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 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 as

described below.

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

PRODUCT MARKING is

located on the rear exterior.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH

MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS

LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE

COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS

APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS

PUBLISHED BY SONY.

Unleaded solder

Boards requiring use of unleaded solder are printed with the lead-

free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

· Unleaded solder melts at a temperature about 40

°C higher than

ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350

°C.

Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

· Strong viscosity

Unleaded solder is more viscous (sticky, less prone to flow) than

ordinary solder so use caution not to let solder bridges occur such

as on IC pins, etc.

· Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

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 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 several times.
