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)

SERVICING NOTES

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the leadfree 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 ﬂ ow)

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.

ELECTRICAL ADJUSTMENT

BIAS ALIGNMENT ADJUSTMENT (DA2400ES: AEP, Continental European, East European, Russian and UK only)

Note: Afer 10 minutes or more have passed since the power supply was

turned on, this adjustment is done.

Connection:

digital voltmeter

CN6102 pin , , 

(CN6104 pin , , , )

CN6102 pin , , 

(CN6104 pin , , , )

+ –

Procedure:

1. Connect a digital voltmeter to the CN6102 (CN6104).

2. Press the [POWER] button to turn on the main power.

3. Adjust the RV400 (RV470, RV500, RV570, RV600, RV670, RV700) so that the digital voltmeter reading is 5 mV to 20 mV.

Adjustment and Connection Location:

– MAIN Board (Conductor Side) –

VIDEO CALIBRATION ADJUSTMENT

Adjustment to decide the standard of the video input signal.

Note: After replacing DIGITAL VIDEO board, or after “SUPER RESET”

of the special menu mode is executed, perform this adjustment.

Connection:

color pattern

generator

color bars 100%

VIDEO board COMPONENT VIDEO COMPO 2 IN jack (J6001)

DVD VIDEO IN jack (J6004)

set

Procedure:

1. “DVD” is selected by using [INPUT SELECTOR] jog.

2. Connect a color pattern generator to the COMPONENT VIDEO COMPO 2 IN jack (J6001) on the VIDEO board and DVD VIDEO IN jack (J6004) on the VIDEO board.

3. Input NTSC color bars signal from the color pattern generator.

4. Press the [POWER] button to turn off the main power

5. While pressing the [2CH/A.DIRECT] and [SPEAKERS (OFF/ A/B/A+B)] buttons, press the [POWER] button to turn on the main power. It enters the test mode, and display as below.

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.

STR-DA2400ES/DG920

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