5 6 7 8 5. PCB PARTS LIST NOTES: 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. A 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%). 560 Ω 56 x 10 1 561 RD1/4PU 5 6 1 J 47k Ω 47 x 10 3 473 RD1/4PU 4 7 3 J 0.5 Ω R50 RN2H R 5 0 K 1 Ω 1R0 RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k Ω 562 x 10 1 5621 RN1/4PC 5 6 2 1 F B • LIST OF WHOLE PCB ASSEMBLIES Mark Symbol and Description 1..FM/AM TUNER UNIT VSX-52TX /KUXJ/CA AXX7172 VSX-1014TX /KUXJC AXX7172 NSP 1..SECONDARY ASSY AWK7814 AWK7818 2..REGULATOR ASSY AWX8364 AWX8367 2..TRANS 2-1 ASSY AWX8372 AWX8372 2..SP/PS ASSY AWX8373 AWX8373 2..DIODE ASSY AWX8376 AWX8376 2..TRANS SIDE ASSY AWX8417 AWX8417 C NSP 1..COMPLEX ASSY AWK7806 AWK7810 2..DISPLAY ASSY AWX8377 AWX8389 2..VOLUME ASSY AWX8378 AWX8378 2..MULTI JOG ASSY AWX8379 AWX8379 2..HEADPHONE ASSY AWX8380 AWX8380 2..FRONT IN ASSY AWX8381 AWX8381 2..AUDIO CONNECT ASSY AWX8382 AWX8382 2..TRANS 1 ASSY AWX8383 AWX8383 2..PRIMARY ASSY AWX8384 AWX8384 2..OPTICAL-IN ASSY AWX8394 AWX8394 2..REAR TOP ASSY AWX8397 AWX8397 D 2..FRONT-IN CONNECT ASSY AWX8416 AWX8416 NSP 1..MAIN ASSY 2..MAIN CONTROL ASSY 2..COMPOSITE V ASSY 2..COMPONENT ASSY 2..S VIDEO ASSY 2..VIDEO SIDE ASSY 2..MULTI CH I/O ASSY AWK7798 AWX8343 AWX8353 AWX8358 AWX8361 AWX8366 AWX8410 AWK7802 AWX8348 AWX8362 AWX8358 AWX8361 AWX8366 AWX8352 NSP 1..POWER AMP ASSY AWK7822 AWK7826 2..TRANS 2-2 ASSY AWX8371 AWX8371 2..12V TRIGGER ASSY AWX8395 Not used E 2..POWER AMP-R ASSY AWX8404 AWX8404 2..POWER AMP IN ASSY AWX8405 AWX8405 2..POWER PROTECT ASSY AWX8406 AWX8406 2..POWER AMP-L ASSY AWX8409 AWX8409 2..VH TR ASSY AWX8411 AWX8411 2..POSI 1 R ASSY AWX8426 AWX8426 2..POSI 1 L ASSY AWX8427 AWX8427 1..DSP ASSY AWX8414 AWX8414 F VSX-52TX 103 5 6 7 8
