Notes on chip component replacement

·Never reuse a disconnected chip component.

· Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

SAFETY CHECK-OUT

After correcting the original service problem, perform the follow-

ing 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. 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 pas-

sive VOM that is suitable. Nearly all battery operated digital

multimeters that have a 2 V AC range are suitable. (See Fig. A)

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 viscou-s (sticky, less prone to flow)

than ordinary solder so use caution not to let solder bridges oc-

cur 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.

ERROR MESSAGES

If there is a malfunction, the display shows a code of two numbers and a message. You can check the condition of the system by message.

Refer to the following table to solve the problem.

messages

cause and response

DEC. EROR

Appears when the signal which the receiver can not decode (example DSD-CD) is input when

"DEC." is set to "DEC. PCM". Set to "DEC. AUTO".

PROTECT

Irregular current output to the speakers. Turn off the receiver and check the speaker connection.

Then turn on the power again. Be comes this display, When short current flowed with breakage of

the power MOS, or when detection resistor becomes open in connection with it.
