SAFETY-RELATED COMPONENT WARNING!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

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.

FLEXIBLE CIRCUIT BOARD REPAIRING• Keep the temperature of the soldering iron around 270 °C during repairing.• Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).• Be careful not to apply force on the conductor when soldering or unsoldering.

SAFETY CHECK-OUTAfter 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 TESTThe AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn 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 2V AC range are suitable. (See Fig. A)

SECTION 1SERVICING NOTES

UNLEADED SOLDERBoards 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 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.

CAUTIONUse of controls or adjustments or performance of proceduresother than those specifi ed herein may result in hazardous radiationexposure.

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

The laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The fl exible board is easily damaged and should be handled withcare.

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.

MODEL IDENTIFICATION

This appliance is classifi ed as a CLASS 1 LASER product under IEC 60825-1:2007. This marking is located on the rear exterior.

SECTION 4ELECTRICAL CHECK

Procedure:1. Turn the power on.2. Input the following signal from Signal Generator to FM antenna input directly.

Carrier frequency : A = 87.5 MHz, B = 98 MHz, C = 108 MHzDeviation : 75 kHzModulation : 1 kHzANT input : 35 dBu (EMF)

Note: Please use 75 ohm “coaxial cable” to connect SG and the set. You cannot use video cable for checking. Please use SG 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 detected and automatic scanning stops.

The stop of automatic scanning means “The station signal isreceived in good condition”.

DVD SECTION

Note:1. DVD block is basically constructed to operate without

adjustment.2. Use YEDS-18 disc (Part No. 3-702-101-01) unless otherwise

indicated.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 following check.

EXPLODED VIEWSNote:• The mechanical parts with no reference number in the exploded views are not sup-

plied.• Items marked “*” are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items.• -XX and -X mean standardized parts, so

they may have some difference from the original one.

• Accessories are given in the last of this parts list.

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

The components identifi ed by mark 9 con-tain confi dential information.Strictly follow the instructions whenever the components are repaired and/or replaced.
