If you have just one pair of speakers hooked up and have both A & B speakers selected you won't get ANY sound out of unit, so check that?

Hi Tracey

Most of these older machine had speaker switches on the front panel. Can you check what they are set to. It may be that both switches(A and B) are set in, or set out. this could present the problem you are having with no sound. turn on just one switch that corresponds the connections you have made on the rear (use speaker A) Another thing to check, is when you first turn on the amp, do you hear a relay click shortly after you switch on. If you don't hear this delayed click, then there may well be a problem in the output stages of the amp. If this is the case, then you will need to take it to a tech to have a look and see what has failed in the amp. Hope this info helps, if you have any questions, I am happy to try and help you further.

regards
robotek

SOURCE: pioneer receiver vsx d814 amp error

The Pioneer VSX-D814 has a couple of Power Hybrid bricks that do all the power amplification. These are the infamous PAC011A. You should have 2 of those in your receiver.

If the amp detects some unusual activities, it may shut down the unit to prevent damage. “Amp Err” usually means some DC in the output.

Disconnect all the speakers and turn on the unit; if it acts normal, reconnect speakers one set at a time very carefully. If the unit still shows the error message you can try to reset it. If the reset works, again carefully reconnect the speakers connections. If the reset does not recover the normal operation of the unit, you may have one of the PAC011A damaged, and the unit will need repair.
The reset can be done by disconnecting the unit power cord for a few minutes, then plug it in and press “FRONT ENTER key + ADVANCED SURROUND key” continuously for 2sec.

Good luck

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

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.

I have a panasonic home theatre model sa-ht900. everything plays fine but i have absolutely no sound at all.possible solutions?



http://www.retrevo.com/support/Pioneer-VSX-D510-Receivers-manual/id/385ci969/t/2/

≥Check the connections.

≥Turn the volume up.

≥Turn muting off.

≥Switch off the unit, determine and correct the cause, then switch the unit on.

Causes include:

-Shorting (bare wires touching) of positive and negative speaker wires.

-Using speakers with an impedance lower than that rated for this unit.

-Straining of the speakers through excessive volume or power.
-Using the unit in a hot environment without proper ventilation.

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.

VSX-D608 Overload and shutdown


Overload is displayed when the amp draw is excessive, and can be caused by different faults.
when Overload is detected, the protection circuit will shut down the unit to prevent further damage.

The first thing to try is hard reset. Shut down the unit for about one hour to drain power completely.
This can fix minor problems that can cause overload, for example electrostatic charge accumulation on internal capacitors.

If that does not fix the problem, then you must find the fault.

Overload can be caused by shorted speakers, wrong impedance speakers, or by a contact on speakers wiring.
Check speakers connection and test different speakers with 6, or better 8 Ohms impedance.

Another test can be done by unplugging all speakers, and reconnecting and testing them one at a time, at a very low volume.
No more than two 4 Ohms speakers can be connected to the unit, or you will get overload.

If the speakers are OK, then preamp, shorted input/output connectors, main power supply or faulty output transistors can draw too much amps causing overloading.

In that case it is recommendable contacting Pioneer at the number listed on the owners manual.

Speakers for pioneer vsx 1018


I think you're making this way more complex than it is.

This unit should have no trouble with any reputable speaker. Don't read too much into short term impedance readings as long as you run only one speaker per channel. Every speaker has a dip somewhere in its frequency range and the Pioneer will probably protect itself and the speaker should impedance or current get too out of whack. This is a high end unit and has plenty of clean power to feed any speakers out there.

I'd buy it if I didn't already have a 6-year old predecessor (VSX-T36TX) that I paid twice as much for and has only 5 amplified channels, less features and lower power output. ;-(

Good luck and happy listening!

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

With the receiver off, press ENTER + ADVANCED SURROUND keys continuously for 2 sec. and it will tell you the fault it encountered. Even if it has a short, it will still protect the speakers; however, it is still a good idea to disconnect all speakers before doing this.

Pioneer VSX 915


Disconnect the speaker leads and see if this stops happening. If it does, connect up the speakers till the problem pops up, and that speaker that makes the problem happen is most likely bad. If the problems still happens with no speakers attached, then there is a problem in the audio output amp, and is going to need service , Good Luck
