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 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-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.

CAUTIONUse of controls or adjustments or performance of procedures other than those specifi ed herein may result in hazardous radiation exposure.

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 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)

SECTION 1SERVICING NOTES

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

The laser diode in the optical pick-up block may suffer electro-static 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.

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.

NOTE OF REPLACING THE IC502 ON THE DMB22 BOARDIC502 on the DMB22 board cannot exchange with single. When these parts on the DMB22 board are damaged, exchange the entire mounted board.

CD SECTION

Note:1. CD Block is basically constructed to operate without adjustment.2. Use YEDS-18 disc (Part No. 3-702-101-01) unless otherwise indicat-

ed.3. Use an oscilloscope with more than 10 M 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 checks.5. Check the focus bias check when optical pick-up block is replaced.

FOCUS BIAS CHECK

Procedure :1. Connect the oscilloscope to CN507 pin 6 (RFMON) and CN507 pin 3 (GND) on the DMB22 board.2. Press the [?/1 STANDBY] button to turn the power on, and

press the [CD/DISC SKIP] button to select CD function.3. Set disc (YEDS-18) and press the [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.

Procedure:1. Turn the power on.2. Input the following signal from Signal Generator to FM an-

tenna 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 auto-

matic scanning stops.

The stop of automatic scanning means The station signal is re-ceived in good condition.
