Question about Pioneer Audio Players & Recorders

Open Question

Have a Pioneer with VSX-839RDS Amp. As soon as I switch it on it cuts out in 1-2 seconds. I have fitted the obvious, failed transiters and resistors and it appreared to come on ok, but produced NO AUDIO. Then for no apparent reason on of the Output Stages suddenly went up in a cloud of smoke again. Please advise what can be done to get it to work properly again. Thanks Mohsin Ravjani 07834905774 mohsinrav@hotmail.com

If it's under warranty..get a new one.
It's an internal breakdown ...tech service only.

SOURCE: Pioneer VSX-D412 AMP-ERR message.

Hello,
The AMP-ERR message in many Pioneer Receivers is caused by some DC in the output. The microprocessor then issues the warning and shuts the unit off. It is definitely not a relay switch. It could be the amplifier power pack, i.e. PAC011A or similar that is faulty or something else. Not easy to repair for the non- experienced DIY.

Good luck

SOURCE: Pioneer VSX-D509S keeps shutting off

Aside from any intrinsic problem with your receiver, the usual suspects are;
1) Poor receiver ventilation. 2) Very high levels of bass. 3) Shorts in the speaker wiring. 4) A rubbing loudspeaker voice coil.

SOURCE: Pioneer audio receiver pre-amp output

It is possible then that the root cause may not be electrical, but acoustic if you're noticing the issue from your listening position.
If you can run a channel test signal identically one channel at a time by positioning your meter less than a foot away and exactly the same distance with each speaker and the level differs by more than 1/2dB, then it's not the acoustics.

How intelligent is Pioneer's vsx amp/rec "power off" protecting mode? Hi, I would like to have an answer to the foregoing title in order to find out if it's worth repairing my Pioneer...


When you remove boards, you may be breaking a circuit somewhere that is causing the shutdown. Pioneer uses rear panel jacks for ground points a lot, and if even one of these screws is out it can cause it to shut down.

No audio output


THE FIX - to audio problems that persist with the VSX-29TX and others using the AWX7272 DSP board is to replace the ROM on the DSP. My unit started failing on and off after 10 years of use! The intermittent DSP board is an Extremely Common and irritating Problem for this model! The replacement IC,(2) resistors + shipping and handling totaled $49.65 and my unit is finally fixed correctly! Don't believe other posts that you can get away with re-soldering; it will continue to fail again and again! Details of fix are:

Replacement for the old Pioneer ROM located at location IC 9374, should be done with the part PD6381A from Pioneer Electronics. You will also need to move (relocate) the 2 resistors (0 Ohm resistors) located at R9372 and R9371 to locations R9374 and R9373.

This component update applies to DSP boards marked as AWX7433, AWX7272.

This fix is validated (from Pioneer) on the VSX-26TX,VSX-27TX,& VSX-29TX it might also work in the VSX-908, VSX-908RDS and others as long as the same DSP board was used.

Let me caution and stress that surface mount soldering skills ARE REQUIRED to do this update! It also doesn't hurt to have excellent vision and/or an eye loop or microscope to check your work. Original ROM's were subject to timing changes internal to the part as a result of HEAT. This model does get HOT! The program was also modified as a further safeguard to re-occurrence.

How to install bose 901 eq to my pioneer vsx-1019ah-k


This works for all models of AV receivers when you want 901's as Front L&R speakers..

Get yourself a nice separate amp, draw the Front L&R pre-out signals from wherever you can find them. On many, there is a pre-amp out for every channel in case you want to run external amps for any channels. That is how my old Pioneer VSX-36TX is equipped. For others, you may have to borrow the signals from a typical Tape- or Adapter-Out RCA pair. Just remember, AV receivers disable digital inputs as soon as you switch in a Tape Monitor, so choose one you won't have to switch IN. The signal Out is always there regardless of the monitor state.

Patch the Active EQ directly off that point (Amp In from the receiver, Amp Out to the new amp). Run all the speaker level settings on the AV Receiver and rock on.

I turn on receiver Pioneer vsx d608, then few seconds later screen flashes "poweroff", then shuts off by itself


Check all speaker wiring for shorts. If nothing is found, unit obviously has circuit problems, have serviced.
