STR-V220 SERVICE MANUAL US Model SPECIFICATIONS — Continued on next page — FM STEREO/FM-AM RECEIVER MICROFILM –1– SAFETY CHECK-OUT After correcting the original service problem, perform the following safety checks 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 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 microampers). 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) To Exposed Metal Parts on Set 0.15µF 1.5kΩ AC voltmeter (0.75V) Earth Ground Fig. A. Using an AC voltmeter to check AC leakage. 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-RELATED COMPONENT WARNING !! COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITH MARK ! 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. –2– TABLE OF CONTENTS 1.

ELECTRICAL PARTS LIST ........................................ 30 SECTION 1 SERVICING NOTE FACTORY SET Mode which sets the preset settings of the unit to that at shipment. Procedure: While pressing the VIDEO button and TV/SAT button together, press the 1/u button to turn on the power. “FACTORY” will be displayed and factory settings executed. INITIALIZATION Mode which erases all the preset settings of the unit. Use this mode when returning the unit to the customer. Procedure: While pressing the VIDEO button, TV/SAT button, and TAPE/MD button together, press the 1/u button to turn on the power. “INITIAL” will be displayed and initialization executed. FLUORESCENT INDICATOR TUBE LIGHTING CHECK Mode which lights up the whole fluorescent indicator tube or partially. Procedure: While pressing the TV/SAT button and TAPE/MD button together, press the 1/u button to turn on the power. The fluorescent indicator tube will light up in about 0.5 seconds, and then start to light up partially. After partial lighting completes, the BASS BOOST indicator will light up, “FINISH” will be displayed, indicating that fluorescent indicator tube lighting check has completed. SWITCHING OF 9 kHz/10 kHz AM CHANNEL STEP The AM channels of this unit can be switched between 9 kHz and 10 kHz. Procedure: Set FUNCTION to AM and turn off the power. While pressing the TUNING + button, press the 1/u button to turn on the power. “9 k STEP” or “10 k STEP” will be displayed, and the channel step will be switched. –3– SECTION 2 GENERAL Front Panel Descriptions 1 25 24 23 22 3 2 21 20 19 18 4 17 5 16 15 6 7 14 13 8 12 11 10 9 Location of Parts and Controls 1 2 3 4 5 6 7 8 9 1/u button VIDEO button TV/SAT button TAPE/MD button CD button TUNER button BASS BOOST indicator MASTER VOLUME knob BALANCE knob 10 11 12 13 14 15 16 17 18 TREBLE knob BASS knob SURROUND ON/OFF button CENTER MODE button EFFECT/DELAY TIME button SURROUND MODE button Numeral (1 to 0) button Display window DIRECT button 19 20 21 22 23 24 25 SHIFT button MEMORY button AM button TUNING + button FM button TUNING – button PHONES jack This section is extracted from instruction manual. –4– STR-V220 SECTION 3 ELECTRICAL BLOCK CHECKING ADJUSTING THE FM/SD SIGNAL SENSITIVITY SECTION 4 DIAGRAMS 4-1. CIRCUIT BOARDS LOCATION SECONDARY board Setting: STANDBY board FM RF SSG FM ANTENNA (75Ω) Set PRIMARY board MAIN board Carrier frequency: 98 MHz Modulation: AUDIO 1 kHz, 75 kHz deviation (100%) Output level: 26 dB (at 75 Ω open) (MAX 35 dB) oscilloscope Main board KEY board TP (IC501 6 pin) Procedure: 1. Set the SSG output level to 26 dB and input the signal. 2. Adjust SFR501 so that the oscilloscope level becomes 0V. 3. Raise the SSG output level slightly (max. 35 dB) when the adjustment in step 2 fails, and repeat steps 1 and 2. NOTE: If the adjustment cannot be performed even when set to 35 dB, the sensitivity may be faulty, etc. Check the antenna terminal connection, FM front end and IF circuit, etc. and perform adjustments again.
