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.

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. 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)

signal

generator

set

Procedure:

1. Turn on the set.

2. Input the following signal from signal generator to FM antenna input directly.

Carrier frequency : A = 87.5 MHz, B = 98 MHz, C = 108 MHz Deviation : 75 kHz Modulation : 1 kHz ANT input : 1 kHz

Note: Use 75 ohm coaxial cable to connect signal generator and the set.

You cannot use video cable for checking.

Use signal generator whose output impedance is 75 ohm.

3. Set to FM tuner function and scan the input FM signal with automatic scanning.

4. Conﬁ rm that input frequency of A, B and C are detected and automatic scanning stops.

When the station signal is received in good condition, automatic scanning stops.

Note:

• All capacitors are in μF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics

and tantalums.

• All resistors are in Ω and 1/4 W or less unless otherwise speciﬁ ed.

• f : internal component.

• 2 : nonﬂ ammable resistor.

• 5 : ﬂ usible resistor.

• C : panel designation.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)

• A : B+ Line.

• B : B– Line.

• Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions.

no mark : TUNER

• Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.

• Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal production

tolerances.

Note:

The components identiﬁ ed by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number speciﬁ ed.
