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 THELIMITS OUTLINED ABOVE ARE INDICATIVEOF A POTENTIAL SHOCK HAZARD ANDMUST BE CORRECTED BEFORE RETURN-ING THE APPLIANCE TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICEMany electrical and mechanical parts in the appliance

have special safety related character istics. These areoften not evident f rom visual inspect ion nor theprotection afforded by them necessarily can be obtainedby using replacement components rated for voltage,wattage, etc. Replacement par ts which have thesespecial safety character ist ics are identif ied in thisService Manual.

Electr ical components having such features areidentified by marking with a on the schematics andon the parts list in this Service Manual.The use of a substitute replacement component whichdoes not have the same safety characteristics as thePIONEER recommended replacement one, shown in theparts list in this Service Manual, may create shock, fire,or other hazards.

Product Safety is continuously under review and newinstructions are issued from time to time. For the latestinformation, always consult the current PIONEERService Manual. A subscription to, or additional copiesof, PIONEER Service Manual may be obtained at anominal charge from PIONEER.

(FOR USA MODEL ONLY)1. SAFETY PRECAUTIONS

The following check should be performed for thecont inued protect ion of the customer and servicetechnician.

LEAKAGE CURRENT CHECKMeasure leakage current to a known ear th ground

(water pipe, conduit, etc.) by connecting a leakagecurrent tes ter such as S impson Model 229-2 orequivalent between the earth ground and all exposedmetal par ts of the appliance (input/output terminals,screwheads, metal overlays, control shaft, etc.). Plugthe AC line cord of the appliance directly into a 120VAC 60 Hz outlet and turn the AC power switch on. Anycurrent measured must not exceed 0.5 mA.

Deviceundertest

XWK3122 and XWK3125 are constructed the same except for the following :

XWZ3792 and XWZ3795 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.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).

7.3.4 AMPLIFIER SYSTEM PROTECTION OPERATION SPECIFICATION

1. DC-abnormality detectionDC detection is only enabled 2 seconds after power-on. If there is a fault in the power amplifier or a high-level signal lower than 5 Hz is input, the DC_DET port becomes “L”. If the “L” is detected, the microprocessor will perform as following flow chart.

In the case of simultaneous detection with the overload protection circuit, DC-abnormality detection is performed preferentially to overload detection.

If the speaker terminals are short-circuited or low-load driving is detected, the OL_DET port becomes “L”. If the “L” is detected, the microprocessor will perform as following flow chart.

*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 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.

4. Fan stop detection operation flow in the DC abnormality detectionIf the fan is forcibly stopped, the 'DC PROT' port becomes "L". Then an abnormality of fan is detected.

*A.MUTE : Audio mute command

↓



The power is shut off. The program restarts.

↓The power key is disabled.

However, when the following keys are pushed so that the key input of a line and the service can be carried out, power can be on.1 TESTMODE ON (A55F+A55F)2 When power off, push FRONT ENTER key + ADVANCED SURROUND key continuously 2sec.

(Effective, only when power-off is carried out by DC detection)

When an abnormality of fan is detected, A.MUTE* is turned on, speaker relay is turned off, the "AMP_ERR" flashes on the display.

If the board connection from Main Ass’y to Amp&Primary Ass’y is interrupted, the BOARD_DET port becomes “H”. If the “H” is detected, the microprocessor will perform as following flow chart.

In the case of simultaneous detection with the overload protection circuit, Board detection is performed preferentially to DC-abnormality detection and Overload detection.

3. Board detection

↓



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.

7.3.5 AMPLIFIER FAILURE DIAGNOSIS FLOW CHART

7.4 CLEANING

Amplifier failure diagnosis flow chart

When DC detection is activated ("AMP_ERR" flashes on the display), failure (damage) of the power amplifier section is considered.As DC detection and fan stop protection circuits commonly use same abnormality detection port in microprocessor, please make sure that the operation of fan motor is in normal condition before proceeding to the troubleshooting of amplifier.

Caution:When release the lock state of power key before repair, please be careful because there is the possibility that more damages will occur when turns on the power once again!

• According to a symptom, perform the following confirmation beforehand.

1) Is the operation of fan motor in normal condition?

2) Are there any Fuses and IC protectors open?

3) After turn on the power, confirm that the supply voltage of the point that can be measured is appropriate.

4) Whether the voltage of pin3 of IC601 or IC602 is equal to (VL-0.7V). If not (eg, equal to VH), then change the corresponding power pack IC601 or IC602.

5) Furthermore, check the output DC voltage of each channel of power pack IC601 and IC602 to limit the failure channel and identify the defect power pack.

• After identify the failure channel, check that each part is not damaged (resistor, diode... etc. value / open / short)

Before shipping out the product, be sure to clean the following positions by using the prescribed cleaning tools:
