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 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 areturn 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. 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 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 2 V AC range are suitable. (See

Fig. A)

SECTION 1

SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro-

static 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.

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.

NOTE OF REPLACING THE IC501, IC502, IC504 AND

IC851 ON THE MB BOARD

IC501, IC502, IC504 and IC851 on the MB board cannot exchange

with single. When these parts on the MB board are damaged,

exchange the entire mounted board.

NOTE OF REPLACING THE IC100 ON THE MBBOARD

Once IC100 on the MB board is exchanged, perform MODEL &

DEST WRITE MODE (refer page 13) before operating the set.
