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. Follo w 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 A C 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 A C range are suitable. (See Fig. A)

TEST MODE

Factory Set Mode

All preset contents are reset to the default setting.

Procedure:

While pressing the [SET UP] and [DIMMER] buttons, press the

?/1 button to turn on the main power. The message “TUNER

FACTORY PRESET” appears and the present contents are reset to the default values.

All Clear Mode

All preset contents are cleared when this mode is activated. Use this mode before returning the product to clients upon completion of repair. Procedure: While pressing the [A.F.D.] and [SOUND FIELD MODE] buttons, press the ?/1 button to turn on the main power. The message “MEMORY CLEAREDd” appears and the memories are reset to the default values.

Sound Field Clear Mode

The preset sound field is cleared when this mode is activ ated. Use this mode before returning the product to clients upon completion of repair.

Procedure:

While pressing the [SOUND FIELD MODE] button, press the

?/1 button to turn on the main power. The message “S.F

Initialize” appears and initialization is performed.

Fluorescent Indicator Tube Test Mode

All fluorescent segments are tested. When this test is acti vated, all segments turn on at the same time, then each segment turns on one after another.

Procedure:

1. While pressing the the ?/1 button to turn on the main power.

2. All segments turn on at the same time, then each segment turns on press the [A.F.D.] button.

[A.F.D.] and [DIMMER] buttons, press

AM Channel Step 9 kHz/10 kHz Selection Mode

Either the 9 kHz step or 10 kHz step can be selected for the AM channel step.

Procedure:

1. Set the FUNCTION to AM. Press the the main power.

2. While depressing the

?/1 button to turn on the main power.

3. Either the message “AM 9kHz Step” or “AM 10kHz Step” appears. Select the desired step.

[PRESET TUNING +] button, press the

?/1 button to turn off

Version Mode

When this mode is used, the microprocessor version number is displayed.

Procedure:

Press three buttons of [SHIFT],

[SOUND FIELD MODE]

and

[TUNING --] simultaneously . The microprocessor version number

appears.

DSP Test Mode

This test is conducted to check if the DSP functions normally.

Procedure:

1. While pressing the [DISPLAY]and [TUNING +] buttons, press the I/1 button to turn on the main power.

2. If the DSP is normal, the message “RWS 1:000 2:000 SYNC” appears.

3. If the DSP is abnormal, characters other than 0 appears at the 000 part of the message.

Note: RWS characters of the message correspond to the digits of 000.

RW means read/write from the system controller (IC1703) to the DSP, and S means the communication between DSP and S-RAM (IC1502, IC1602). For example, if the writing of the system controller failed, 0*0 (* is a character other than 0) appears. Also, 1 and 2 indicates DSP1 (IC1501) and DSP2 (IC1601), and 1:000 and 2:000 show the test results of DSP1 and DSP2 respectively.

Demonstration Mode

Procedure:

While pressing the [SET UP] button simultaneously, press the

?/1 button to turn on the main power. The set enters the DEMO

mode. Wait a while, then the demonstration starts. If the ?/1 button is pressed often the demonstration has started, the power is turned off, and the demonstration resumes if the ?/1 button is pressed again.
