PCB PARTS LIST • LIST OF WHOLE PCB ASSEMBLIES Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5 6 1 4 7 3 R 5 0 1 R 0 5 6 2 1 NOTES: 560 Ω 47k Ω 0.5 Ω 1 Ω RD1/4PU J RD1/4PU J RN2H K RS1P K 56 x 10 1 47 x 10 3 R50 1R0 561 473 5.62k Ω RN1/4PC F 562 x 10 1 5621 Mark Symbol and Description VSX-55TXi /KUXJI/CA VSX-53TX /KUXJI/CA 1..FM/AM TUNER MODULE AXQ7231 AXQ7231 NSP 1..REGULATOR ASSY AWK7784 AWK7731 2..PRIMARY ASSY AWX7968 AWX7968 2..TRANS 1 ASSY AWX7969 AWX7969 2..TRANS 2-2 ASSY AWX7970 AWX7970 2..FAN DRIVE ASSY AWX7976 AWX7976 2..POWER AMP IN ASSY AWX7982 AWX7982 2..REGULATOR ASSY AWX8303 AWX7967 2..7.1 CH I/O ASSY AWX8306 AWX7973 NSP 1..COMPLEX ASSY AWK7788 AWK7791 2..RS232C ASSY AWX7966 Not used 2..12V TRIGGER ASSY Not used AWX8310 2..VOLUME ASSY AWX7971 AWX7971 2..MULTI JOG ASSY AWX7972 AWX7972 2..INPUT CONNECT ASSY AWX7974 AWX7974 2..FRONT IN ASSY AWX7977 AWX7977 2..OPTICAL IN ASSY AWX7978 AWX7978 2..HEADPHONE ASSY AWX7980 AWX7980 2..DIODE ASSY AWX8017 AWX8017 2..VH TR ASSY AWX8018 AWX8018 2..SP/PS ASSY AWX8307 AWX7975 2..V-AUDIO IN ASSY AWX8313 AWX7964 2..TRANS 2-1 ASSY AWX8326 AWX8326 NSP 1..MAIN ASSY AWK7776 AWK7780 2..MIC & F.OPT IN ASSY AWX7981 AWX7981 2..MIC AMP ASSY AWX8004 AWX8004 2..FAN CONNECTION ASSY AWX8005 AWX8005 2..MAIN CONTROL ASSY AWX8285 AWX8289 2..COMPONENT ASSY AWX8293 AWX8295 2..DSP CONNECTION ASSY AWX8299 AWX8024 2..COAXIAL IN ASSY AWX8300 AWX8323 2..VIDEO ASSY AWX8311 AWX7962 NSP 1..POWER AMP ASSY AWK7792 AWK7733 2..POWER AMP-L ASSY AWX7984 AWX7984 2..POWER AMP-R ASSY AWX7985 AWX7985 2..POWER AMP-C ASSY AWX7986 AWX7986 2..DISPLAY ASSY AWX8315 AWX7983 1..DSP ASSY AWX8249 AWX8249 1..1394 ASSY AWK7768 Not used www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com VSX-55TXi 133 5 6 7 8 5 6 7 8 C D F A B E • CONTRAST OF PCB ASSEMBLIES AWX8306 and AWX7973 are constructed the same except for the following : AWX8313 and AWX7964 are constructed the same except for the following : AWX8300 and AWX8323 are constructed the same except for the following : AWX8293 and AWX8295 are constructed the same except for the following : AWX8311 and AWX7962 are constructed the same except for the following : AWX8285 and AWX8289 are constructed the same except for the following : A7.1CH I/O ASSY Mark Symbol and Description AWX8306 AWX7973 1301–1304 4P PIN JACK AKB7075 Not used CN1301–CN1304 4P PIN JACK Not used AKB7015 BV-AUDIO IN ASSY Mark Symbol and Description AWX8313 AWX7964 1201, 1203 4P PIN JACK AKB7075 Not used CN1201, CN1203 4P PIN JACK Not used AKB7015 CN1205 6P PIN JACK AKB7162 AKB7009 HCOAXIAL IN ASSY Mark Symbol and Description AWX8300 AWX8323 IC1681 PCM2902EG Not used IC1682 TC7SET08F Not used C1680, C1697 CKSRYB103K50 Not used C1681 CEAT470M16 Not used C1683-C1686, C1689, C1690, C1698 CKSRYB104K16 Not used C1687 CCSRCH220J50 Not used C1688 CCSRCH180J50 Not used R1681 RS1/16S152J Not used R1682, R1683 RS1/16S220J Not used R1686 RS1/16S105J Not used R1687 RS1/16S470J Not used R1689 RS1/16S222J Not used R1690 RS1/16S101J Not used X1681 CRYSTAL RESONATOR (12.0MHz) ASS7047 Not used JA1681 USB CONNECTOR DKN1237 Not used JA1802 2P PIN JACK AKB7148 AKB7131 ICOMPONENT ASSY Mark Symbol and Description AWX8293 AWX8295 JA1001–JA1003 3P PIN JACK VKB1151 VKB1150 KVIDEO ASSY Mark Symbol and Description AWX8311 AWX7962 JA901–JA903 COMB.

The time is 4.8 seconds after power-on. (Control of the relay system is enabled 5.2 seconds after power-on.) Only DC detection is enabled 2 seconds after power-on to activate it before other protection functions. 1 Fan control 1) Fan control 2) Fan detection If the fan is forcibly stopped, the FAN_DET port becomes "L". Detecting "L" the microcomputer performs the following operations: 1. System muting on 2. Protection relays off The warning indication "FAN STOP" appears (flashing) on the FL display. If this status continues for more than 3 seconds, the power is turned off (for Standby mode). If the port becomes "H" within 3 seconds, the unit resets automatically. FAN_DET port performs the chattering check for 1 msec. In addition, there is the case that detection delays for maximum 20 msec because performs monitor of FAN_DET port with a main loop. 3) Thermistor open detection If a total (total of 50 times) of A/D value (TEMPIN) for one second is less than 250, the indication "THDCT NG" flashes. If this status continues for 3 seconds, the power becomes the standby mode. 2 Overload detection (abnormality detection) If the speaker terminals are short-circuited or low-load driving is detected, the OL_DET port becomes "L". Detecting "L" edge interrupt in an interrupt process, the microcomputer performs the following operations: 1. System muting on 2. Speaker relay off (Control with the display microcomputer) 3. Power off (Standby mode) 3 DC detection (defect detection) Only DC detection is enabled 2 seconds after power-on. If there is a fault in the power amplifier or a high-level signal lower than 5 Hz is input, the DC_DET port becomes "L". Detecting "L" the microcomputer performs the following operations: 1. System muting on 2. Speaker relay off (Control with the display microcomputer) The warning indication "AMP ERR" appears on the FL display. If this status continues for more than 3 seconds, the power is turned off (for Standby mode) and flashes the standby LED. Do not accept the key input afterward. (Flash it always till turns the primary side off.) If the port becomes "L" within 3 seconds, the unit resets automatically. DC_DET port performs the chattering check for 1 msec. In addition, there is the case that detection delays for maximum 20 msec because performs monitor of DC_DET port with a main loop. Even if turns the primary side off and turns on once again, standby LED flashes as it is. If detects DC once and turned the power off, do not accept the key input afterward. However, power on is possible when the following key was pressed to be able to key input in the protection line and service. 1. Test mode (remote control code : A55F) 2.

Because this receiver cannot diagnose the amplifier section by an electricity state by structure, please diagnose it in the following steps. Caution: When release the STBY (flashes) state before repair, Because there is the case that the damage progresses when turns the power on once again, please be careful. • According to a symptom, perform the following confirmation beforehand. 1. Are not Fuse and IC protector opening it? 2-a. When can turn on electricity, confirm that supply voltage of the point that can measure is appropriate. 2-b. Furthermore, confirm that voltage ((in a no signal) DC and the appropriate signal output) between GND and R4621- 4627 (Either of the amplifier side and the speaker terminal side is possible) (Or remove either of CN4601-4604). And limit failure CH. If was able to limit failure CH, diagnose the CH in the following steps. • Use the tester basically and check that each part is not damaged (resistance value / open / short circuit). About parts with damaged possibility, explain FL ch to an example in order. 1. R4131, 4132 (ACN7107: 0.1 Ω, 1W chip drain resistor) IC 4102, 4103 (PBD001A: Nch, PBD002A: Pch output POWER MOS Tr.) 2.
