Obstawiałbym uszkodzenie selektora analogowych wejść. Na początek sprawdź wszystkie napięcia zasilające, zwłaszcza te które dochodzą na płytkę selektora. Układ nie grzeje się zbytnio? Niestety service manual który znalazłem jest bardzo ubogi :( Dołączam też service manual do modeli VSX-521-K, VSX-821-K i VSX-921-K, wspomniany również pod numerem RRV4167 w tym ubogim manualu. Sekcja analogowych wejść pewnie jest identyczna.

(FOR USA MODEL ONLY)
1. SAFETY PRECAUTIONS
The following check should be performed for the
continued protection of the customer and service
technician.
C
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.
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 120 V
AC 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.

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 & gt; 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.

1. SERVICE PRECAUTIONS
1.1 NOTES ON SOLDERING
A
• 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).
B
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.

[2] Reset mode for numbers of protection detections
[Purpose]
For clearing all the counts of protection detections.
(This mode resets the counts of protection detections.)
[How to enter/exit]
During Standby mode, simultaneously press and hold the [ALC/STANDARD SURR] and [STANDBY/ON] keys
for 10 seconds to enter this mode.
The display will return to the normal indication when no key operation is performed for 5 seconds.

1. When the procedures for Reset mode for numbers of protection detections are completed, all the counters will be
reset to " 000. "
2. Prohibitions:
The protection detection counts cannot be cleared (reset to 000) with the MEMORY CLEAR process.
They can only be cleared when the procedures of Reset mode are completed.

For detection of a TEMP error, the unit monitors both the TR_DET and PROTECT2 signals. If a TEMP error is detected,
the processes shown below will be performed. The processes shown below are rough operational specifications and are
not the actual commands from the mounted components.
After a TEMP error is detected, the count of protection activation detections will be updated.

A
Note:
(1) Even if the unit shown in the photos and illustrations in this manual may differ from your product, the
procedures described here are common.
(2) For performing the diagnosis shown below, the following jigs for service is required:
• Board to board extension jig cable (GGD1733)
• Board to board extension jig cable (GGD1734)
• 31P extension jig FFC (GGD1738)
• 9P extension jig cable (GGD1739)
• 13P extension jig cable (GGD1740)

1. Discharging
[1] MAIN Assy Capacitor (C55, C58)
C
[Procedures]
(1) Unplug the power cord.
(2) Disconnect the 10P connector from CP403 of the AMP Assy between CN3 of the MAIN Assy.
(3) Connect +B and –B terminal of the D7, using resistor leads with 47 - 100 ohms (2 W or higher), for discharging.
∗ Discharging time: 30 - 60 seconds, depending on the level of resistance.
(4) Check that the voltage between the +B and –B terminals is less than 1 V, using a tester.
∗ Be sure to connect the GND terminal of the tester to the chassis.
∗ If the voltage is still 1 V or higher, repeat Step (3).

[Note]
During repair, before checking the MAIN Assy, etc., with the rear chassis removed, be sure to connect the
GND terminal of the main capacitor to the chassis back (speaker chassis), as shown below, then connect the
power cord.
Without grounding connection, the protection circuit will be activated.
After repairing, be sure to remove the ground wire before reassembling.

adjustment of that channel is required. (Idle current adjustment for another channel is not required.)
However, when any capacitors are replaced, the adjustment is not required.
(The following circuit diagram is for SL channel, but another channel also has same circuit diagram and same adjustment is
required)

12. PCB PARTS LIST
NOTES:
Parts marked by “NSP” are generally unavailable because they are not in our Master Spare Parts List.
The & gt; 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%).
