Question about Pioneer VSX-52TX Receiver

1 Answer

Pioneer VSX-52 Elite Receiver Dc offset problem..

I have +45V. on emitter resistor R146 of Front Right channel !
all resistors..Q2-Q4, Q114-Q116 checks ok. I think is dc coming from
Q104, since voltages read different compare to Q103 I need to know what are Q103 and Q104 ? they are 6 legged (3 each side) small rectangular transistor,the marking on them: '1240' are they FET or Diff.Amp ? I need to know the part number, and where to order ? Any help will be greatly appreciated.. Thank You.

Voltages will read differently because the output voltage is wrong.
They are not FET and with all due respect, if you are not aware of what they are, you don't stand much chance of reading the service manual and affecting a repair.
Take it to an authorised Pioneer Repair Agent.

Which speakers do you have connected?
if your speakers are too "heavy" in terms of Ohm, this is the cause.

Possible solution: You set up your remote to run your amp from the TV control, using the AQUOS Link. Even though your amp is out of the loop, it's still recognized by the TV. You might have to reset the TV back to default and run the AQUOS Link again.

SOURCE: Pioneer VSX-D411 receiver "Amp Error" message

Hello,
Unfortunatelly your receiver has failed. The front panel is telling you one of the power modules is probably bad. Not an DIY type of repair. These parts are near $40.00, plus cost of replacing.
Look at options to replace your trusted receiver with a new one.
Good luck

What does it mean when my Advanced MCACC light blinks on and off? Also, the power button isn't working.


It is in protect mode. Try holding the advanced surround and power buttons. If it turns on but turns right back off, you most likely have a bad amp channel that needs to be repaired.

I have a constant "crackling" noise in the left channel. I've replaced all 4 power transistors. The crackling is still there. Any clues?


Look for an open resistor in that channel. could be the large emitter resistor, or one of the low-ohm flame-proof resistors.

I would also replace 2sa992 (2pcs) and 2sc1845 on preamp board- sometimes they look ok when you test them by regular meter. Check 1.2 kOm and 4.7ohm resistors at preamp pcb. Check diodes on output pcb (could be smd type, connected from base of output transistors to emitter i think)

My pionner audio video multi changer receiver vsx-498 shuts off then turns on when the receiver is on how can i fix it


The problem is not clear. Does the unnamed multichanger turn of/on wit hthe VSX-498 or is the VSX-489 having power issues?

Is the power cord of the multichanger plugged into the back of the VSX maybe the outlet is SWITCHED with the power state of the VSX..
