Power requirements 120 V AC, 60 Hz Power output (DIGITAL MEDIA PORT) DC OUT 5 V, 0.7A MAX Power consumption 170 W Power consumption (during standby mode) 0.3 W (when "CONTROL FOR HDMI" in VIDEO menu is set to "CTRL OFF") Dimensions (w/h/d) (Approx.) 17 × 6 1/4 × 12 5/8 inches (430 × 157.5 × 318 mm) including projecting parts and controls Mass (Approx.) 17 lb 4 oz (7.8 kg)
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)

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 COMPONET 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.

STR-K7200 SECTION 1 SERVICING NOTES
TABLE OF CONTENTS 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 viscou-s (sticky, less prone to flow) 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 IC3511 AND IC3513 ON THE HDMI BOARD IC3511 and IC3513 on the HDMI board cannot exchange with single. When IC3511 and IC3513 on the HDMI board are damaged, exchange the entire mounted board. NOTE OF REPLACING THE IC1131 ON THE DIGITAL AB BOARD IC1131 on the DIGITAL AB board cannot exchange with single. When IC1131 on the DIGITAL AB board is damaged, exchange the entire mounted board.

After press the [TUNING MODE] button, DCAC Factory test mode will start, below display will show: "DCAC x" x = 1, 2, 3, 4 If there is error happen, below display will show: "ERR SD0x" x = 1 D1501 or R1530 problem x = 2 D1502 problem x = 3 D1503 problem x = 4 D1504 problem
2. DCAC board Checking
Connect front left speaker of the receiver and AUTO CAL microphone. Turn [MASTER VOLUME] jog, there will be test tone sound output from front left speaker, and the display will change accordingly. "AD - xxx" xxx = 0 to 255 (depends on loudness of test tone)
RE-BOX CLASSIFICATION TEST MODE Procedure: 1. While pressing the [MEMORY/ENTER] and [INPUTMODE] buttons, press the [?/1] button to turn on the main power. 2. The message "R.BOX[][][]XX" appears. XX: times set powered on VACS CONTROL TEST MODE The VACS feature of the amplifier is turned off purposely. Procedure: 1. While pressing the [MEMORY/ENTER] and [2CH] buttons, press the [?/1] button to turn on the main power. 2. The message "VACS OFF" appears.

STR-K7200 SECTION 5 ELECTRICAL CHECK
FM AUTO STOP CHECK
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. Confirm that input frequency of A, B and C are detected and automatic scanning stops. When the station signal is received in good condition, automatic scanning stops.
