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. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING 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. A subscription to, or additional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER. Leakage current tester Reading should not be above 0.5 mA Device under test Test all exposed metal surfaces Also test with plug reversed (Using AC adapter plug as required) Earth ground AC Leakage Test (FOR USA MODEL ONLY) WARNING This product may contain a chemical known to the State of California to cause cancer, or 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.

Please replace the wiring and cables to the original state after repairs. In addition, be sure that there are no pinched wires, etc. 7 Make sure screws and soldering scraps do not remain inside the product. Please check that neither solder debris nor screws remain inside the product. 8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord. Damaged power cords may lead to fire accidents, so please be sure that there are no damages. If you find a damaged power cord, please exchange it with a suitable one. 9 There should be no spark traces or similar marks on the power plug. When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary. a Safe environment should be secured during servicing. When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely. 2.

SERVICE PRECAUTIONS 1.1 NOTES ON SOLDERING 1.2 CAUTION • For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering. • Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron. Do NOT use a soldering iron whose tip temperature cannot be controlled. Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden). The following lead-free solders are available as service parts: • Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia. • Discharging For more detail, please refer to “7. DISASSEMBLY - 1. Discharging”. • Notes on Ground Points Connection For more detail, please refer to “7. DISASSEMBLY - 2. Notes on Ground Points Connection”. 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 6 VSX-820-K 1 2 3 4 A B C D E F 1 2 3 4 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***
