Health & Safety CodeSection 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 SX-315 3 5 6 7 8 5 6 7 8 C D F A B E [Important Check Points for Good Servicing] In this manual, procedures that must be performed during repairs are marked with the below symbol.

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 • Conversion list of Ref.

GENERAL INFORMATION 7.1 DIAGNOSIS 7.1.1 TROUBLE SHOOTING The Protection circuit is activated by DC or overcurrent detection. Detection method: The voltage at the Protection port (Pin 7) of the microcomputer becomes low. Time required for detection: 2.5 sec after the power is turned on Operation when the Protection circuit is activated: • Mute: ON • Speaker Relay: OFF • The unit immediately enters Standby mode. Recovery method: Press the STANDBY key twice. When the DC detection circuit is not normal When the overcurrent detection circuit is not normal • BD501 and BD502 are in failure or their peripheral circuits are short-circuited. • Power amp section is in failure. • Protection circuit is in failure. • Microcomputer is in failure. (pin 7: protection) • Power amp section is in failure. • Protection circuit is in failure. • Microcomputer is in failure. (pin 7: protection) • Only when the signal is output, short-circuiting of the output circuit is suspected. 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 SX-315 44 1 2 3 4 1 2 3 4 C D F A B E Does an F801 (main fuse) blow out? Yes • The wires of primary and secondary sides of the main transformer are short-circuited. Transformer is in failure. • BD501 and BD502 are in failure. • Power transistors are in failure (short-circuited). Are R801 and R802 (0.22Ω, 1W) open circuited? Yes • D801 and D802 are in failure. • IC801 is in failure. • Short-circuiting of these peripheral circuits. Are R803 and R804 (0.22Ω, 1W) open circuited? Yes • D803-D806 are in failure. • IC802 and IC803 are in failure. • Short-circuiting of these peripheral circuits. Does IC806 (ICP-N15) open circuited? Yes • IC805 is in failure or its peripheral circuits are short-circuited.
