WARNING This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm. Health & Safety Code Section 25249.6 – Proposition 65 NOTICE (FOR CANADIAN MODEL ONLY) Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts must be of identical designation. REMARQUE (POUR MODÈLE CANADIEN SEULEMENT) Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les pièces de remplacement doivent avoir la même désignation. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURN- ING THE APPLIANCE TO THE CUSTOMER. 2. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current PIONEER Service Manual.

SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA. Device under test Leakage current tester Earth ground Reading should not be above 0.5 mA Also test with plug reversed (Using AC adapter plug as required) Test all exposed metal surfaces AC Leakage Test 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-D712-K 3 5 6 7 8 5 6 7 8 C D F A B E [ Important symbols for good services ] In this manual, the symbols shown-below indicate that adjustments, settings or cleaning should be made securely.

PCB PARTS LIST 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 No. Description Part No. LIST OF ASSEMBLIES 1..MAIN ASSY XWK3092 1..DSP ASSY AWX1083 NSP 1..AMP & PS ASSY XWK3083 2..AMP & PRIMARY ASSY XWZ3667 2..REGULATOR ASSY XWZ3675 2..AMP INPUT ASSY XWZ3678 NSP 2..TRANS1 ASSY XWZ3680 2..TRANS2 ASSY XWZ3683 NSP 2..TRANS3 ASSY XWZ3686 NSP 2..BINDER ASSY XWZ3690 NSP 2..HOLDER ASSY XWZ3692 NSP 1..COMPLEX ASSY XWK3076 2..VIDEO ASSY XWZ3645 2..FRONT ASSY XWZ3648 2..6CH IN ASSY XWZ3649 2..POWER SW ASSY XWZ3651 2..R.

DC-abnormality detection In the case of simultaneous detection with the overload protection circuit, DC-abnormality detection is performed preferentially to overload detection. In the case of simultaneous detection with the overload protection circuit, Board detection is performed preferentially to DC-abnormality detection and Overload detection. *A.MUTE : Audio mute command ↓ The abnormality continues for 3 seconds. ↓ Continues. ↓ Recovery The power is shut off. The program restarts. ↓ The power key is disabled and Standby LED blinks. But be switched on with the following methods. 1 TESTMODE ON (A55F+A55F) 2 When power off, push FRONT ENTER key + ADVANCED SURROUND key continuously 2sec. (2: When a DC abnormality is detected and the power is shut off.) 2. Overload detection ↓ The abnormality continues for 3 seconds. ↓ Continues. ↓ Recovery The power is shut off. The power is shut off even if the unit recovers. When a DC abnormality is detected, A.MUTE* is turned on, speaker relay is turned off, then "AMP_ERR" flashes on the display. When an overload is detected, A.MUTE* is turned on, speaker relay is turned off, then "OVERLOAD" flashes on the display. 3. Board detection ↓ The abnormality continues for 3 seconds. ↓ Continues. ↓ Recovery The power is shut off. The power is shut off even if the unit recovers. When an boad error is detected, A.MUTE* is turned on, speaker relay is turned off, then "BOAD ERR" flashes on the display.
