CONTRAST OF MISCELLANEOUS PARTS CONTRAST TABLE VSX-820-K/CUXCNSM and VSX-920-K/UXCNCB are constructed the same except for the following: 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. Screws adjacent to mark on product are used for disassembly. For the applying amount of lubricants or glue, follow the instructions in this manual. (In the case of no amount instructions, apply as you think it appropriate.) Nos. indicate the pages and Nos. in the service manual for the base model. NOTES: 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 RD1/4PU J RD1/4PU J RN2H K RS1P K 56 x 101 47 x 103 R50 1R0 561 473 RN1/4PC F 562 x 101 5621 5 2 6 1 Mark No. Symbol and Description VSX-820-K/CUXCNSM VSX-920-K/UXCNCB Remarks PCB ASSEMBLIES NSP 1..MAIN ASSY 7025HK0916010-IL 7025HK0917060-IL P68-16 2..MAIN ASSY 7028069111010-IL 7028069321010-IL P68-6 2..PT ASSY 7028069112010-IL 7028069325010-IL P68-9 2..CNT2 ASSY 7028069113010-IL 7028069322010-IL P68-4 2..HEADPHONE ASSY 7028069114010-IL 7028069324010-IL P68-7 2..HP_GUIDE ASSY 7028069115010-IL 7028069323010-IL P68-5 2..MIC ASSY 7028069116010-IL 7028069327010-IL P68-10 2..GUIDE_L ASSY 7028069117010-IL 7028069328010-IL P68-11 2..GUIDE_R ASSY 7028069118010-IL 7028069329010-IL P68-8 2..CNT1 ASSY 7028069119010-IL 7028069326010-IL NSP 1..VIDEO ASSY 7025HK0916013-IL Not used P68-12 2..VIDEO ASSY 7028069141010-IL Not used NSP 1..VIDEO ASSY Not used 7025HK0917062-IL P68-12 2..VIDEO ASSY Not used 7028069301010-IL P68-3 2..SPEAKER ASSY Not used 7028069302010-IL NSP 1..FRONT ASSY 7025HK0916011-IL 7025HK0917067-IL P68-13 2..F-VIDEO ASSY 7028069123010-IL 7028069124010-IL NSP 1..INPUT ASSY 7025HK0916012-IL 7025HK0917061-IL P68-1 2..INPUT ASSY 7028069131010-IL 7028069291010-IL NSP 1..SPEAKER ASSY 7025HK0916014-IL Not used P68-3 2..SPEAKER ASSY 7028069151010-IL Not used NSP 1..DSP ASSY 7025HK0916015-IL 7025HK0917063-IL P68-19 2..DSP ASSY 7028069161010-IL 7028069311010-IL P68-17 2..REG ASSY 7028069162010-IL 7028069312010-IL NSP 1..HDMI ASSY 7025HK0916018-IL 7025HK0917064-IL P68-18 2..HDMI ASSY 7028069191010-IL 7028069331010-IL NSP 1..USB ASSY 7025HK0916016-IL 7025HK0917066-IL P68-20 2..USB ASSY 7028069171010-IL 7028069173010-IL 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 4 VSX-920-K 1 2 3 4 A B C D E F 1 2 3 4 NSP 1..AMP ASSY 7025HK0916019-IL 7025HK0917065-IL P68-2 2..AMP ASSY 7028067523010-IL 7028069231020-IL PACKING SECTION P65-7 Operating Instructions (En/Frca/Es) 5707000003160-IL Not used Operating Instructions (En/Sp) Not used 5707000003260-IL P65-10 Box, Gift 6007211700060-IL 60072117000D0-IL EXTERIOR SECTION P68-22 Power Trans. 8200960610590-IL 8200960610700-IL P68-27 Cable, Flat Card 1.25 N712232533810-IL N712232513880-IL P68-30 Sheet 1210210762000-IL 1210211232000-IL P68-35 Panel Front 3067214861000-IL 3067214861010-IL P68-38 Chassis Back 3207213456000-IL 3207213456400-IL Posistor Not used F320121021240-IL No. 69 NSP Label Getter 920U Not used 5507000004550-IL NSP Label Hot Surface Not used 5507000003730-IL Mark No. Symbol and Description VSX-820-K/CUXCNSM VSX-920-K/UXCNCB Remarks 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 5 VSX-920-K 5 6 7 8 5 6 7 8 A B C D E F EXPLODED VIEWS EXTERIOR SECTION 2.

PCB PARTS LIST - Meaning of the figures and others in the parentheses in the parts list. Example) IC 301 is on the point (face A, 91 of x-axis, and 111 of y-axis) of the corresponding PC board. IC 301 (A, 91, 111) IC NJM2068V 5 6 2 1 1 R 0 R 5 0 5 6 1 4 7 3 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. 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 47 k ohm (tolerance is shown by J = 5%, and K = 10%). 560 Ω → 56 × 101 → 561 ...................................................................RD1/4PU J 47 kΩ → 47 × 103 → 473 ...................................................................RD1/4PU J 0.5 Ω → R50 .................................................................................................RN2H K 1 Ω → 1R0 .................................................................................................RS1P K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62 kΩ → 562 × 101 → 5621 .................................................................RN1/4PC F JA*** JACK***, JK*** RY*** RLY*** T*** PT*** X*** XTAL***, RES*** (CERAMIC) FU*** F*** V*** FLT*** S*** SW***, VEC*** (ENCODER) L*** FB*** CN*** CP***, PN*** Q*** Q***FL, Q***FR, Q***C, Q***SL, Q***SR D*** ZD*** - SCHEMATIC DIAGRAM and PCB CONNECTION DIAGRAM - PCB PARTS LIST Mark No. Description Part No. A F INPUT ASSY SEMICONDUCTORS IC 801 J084152180010-IL IC 802-804 J121456000080-IL Q 801,803,805,806 INC2001AC1 Q 802,804,807,809 J520101411210-IL Q 808,810,812,814 INC2001AC1 Q 813,817,838,839 J520101411210-IL Q 815,816 J5441170Y0050-IL Q 818 J522104411210-IL Q 819,821,822,826 INC2001AC1 Q 828,830,832 INC2001AC1 D 801-810,813-818 K005041480030-IL D 9801,9802 (ZD801,802) MTZJ6R8(B) MISCELLANEOUS JA 801 TER,RCA 6PIN G603610A0211Y-IL JA 802,803 TER,RCA 6PIN G603610A02000-IL CN803 CONNECTOR(19P) L101100031910-IL CN806 CONNECTOR(14P) L101100031410-IL CN807 CN.WAFER 2.0MM L101100030510-IL CN8805 CN.WAFER 2.0MM L101100040710-IL B F AMP ASSY SEMICONDUCTORS Q 1204,1208 J5023200B0050-IL Q 1206,1207 J5000992F0050-IL D 1205 1SS133 MISCELLANEOUS L 1201 COIL,FILTER-INDUCTOR D330256800010-IL VR1201 VR,SEMI CARBON MOLD C541102315000-IL RESISTORS R 1201,1202 C0604R7065050-IL R 1207 C060012263050-IL R 1218,1219 C060010065050-IL R 1222 C060047065060-IL > R 1231,1232,1238,1239 N113136647820-IL R 1234,1235 N113135656220-IL R 1236,1237 C060010163050-IL Other Resistors RD1/4PU###J CAPACITORS C 1203,1204 D00410107D051-IL C 1206,1207 D02010406C060-IL C 1210 D00447127D050-IL C 1212 D02010206C060-IL C 1214 D00033006D051-IL C F SPEAKER ASSY SEMICONDUCTORS Q 401-405 J522102371210-IL D 401-410 K005041480030-IL MISCELLANEOUS JA 401 TER,BOARD SCREW 8P G614108V1010M-IL JA 402 TER,BOARD SCREW 6P G613602A0200Y-IL RY401-403,405 RELAY G680120503020-IL RY404 RELAY G680240202030-IL D F HEADPHONE ASSY Mark No. Description Part No. 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 71 VSX-920-K 5 6 7 8 5 6 7 8 A B C D E F SEMICONDUCTORS D 705,706 K005041480030-IL MISCELLANEOUS JA 701 JACK,D6.5 G402PJ612AG0Y-IL E F MIC ASSY SEMICONDUCTORS D 715,716 K005041480030-IL D 9705-9707 (ZD705-707) UDZS5R1(B) MISCELLANEOUS JA 702 JACK,D3.5 G401PJ354H40Y-IL G F PT ASSY SEMICONDUCTORS Q 126,128,131,134 J5001268B0050-IL Q 127,129,130,132 J5023198Y0000-IL Q 133,135,136 J5023198Y0000-IL D 112,113 K005041480030-IL D 9110 K06603R34P400-IL MISCELLANEOUS CN201 CN.WAFER 2.0MM L101100030510-IL H F HP_GUIDE ASSY MISCELLANEOUS CN601 CONNECTOR(4P) L101100030410-IL I F CNT1 ASSY MISCELLANEOUS CN121 (CN121A,121B) CN.WAFER 2.0MM L101100030710-IL J F CNT2 ASSY CNT2 ASSY has no service part.
