TABLE OF CONTENTSSAFETY CHECK-OUTAfter 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 TESTThe 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)

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostat-ic 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 fl exible board is easily damaged and should be handled with care.

NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused on the disc refl ective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

UNLEADED SOLDERBoards 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 MARKUnleaded 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.

SECTION 5ELECTRICAL CHECKS

FM TUNE LEVEL CHECK

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 kHzModulation : 1 kHzANT input : 35 dBu (EMF)

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 tune A, B and C signals.4. Confi rm “TUNED” is lit on the display for A, B and C sig-

nals.

When the selected station signal is received in good condition, “TUNED” is displayed.

Note:1. CD Block is basically constructed to operate without adjust-

ment.2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicat-

ed.3. Use an oscilloscope with more than 10 MΩ impedance.4. Clean the object lens by an applicator with neutral detergent

when the signal level is low than specifi ed value with the fol-lowing checks.

5. Check the focus bias check when optical pick-up block is re-placed.

FOCUS BIAS CHECK

Procedure:1. Connect oscilloscope to TP121 (RFI) and TP124 (VC) on the

CD board.2. Press the [?/1] button to turn the power on.3. Set disc (YEDS-18) on the disc tray and press the [CD u]

button to playback.4. Confi rm that oscilloscope waveform is as shown in the fi gure

below. (eye pattern) A good eye pattern means that the diamond shape (◊) in the

center of the waveform can be clearly distinguished.
