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

After performing the tests mentioned prior, if you determine that the amplifier is damaged and needs replaced you can do this for about $30 USD yourself. But, I do not recommend that you attempt this if you have no prior electronics training and experience, there are many sensitive components in this unit.

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.

Amp error pioneer


Hi pat,

For pioneer Amp error:

It means that microprocessor has detected an abnormal DC voltage:

Speaker relay will be Off, then flash "AMP_ERR" on display.

If the AC plug is pulled off within 60 sec,

and then it is plugged in again, the unit will be reset for 60 sec.

Problem for Pioneer VSX-818V-K 5.1 Channels Receiver Surround sound doesn't work, display reads 2CH IN,surround speakers are enabled,automatic test will find surrand speakers


Test with an surround sound media ie. Blu-ray or DVD)_. Disconnect the front and all other speakers that are working to see if sound from the missing speakers are heard. If this doesn't work then start by tracing and checking all the wires from the receiver to the speakers for bad/shorted/open connections.

PLEASE VOTE IF THIS WAS HELPFUL. THANKS & GOOD LUCK.

Pioneer vsx-519 no sound from center and surround


Make sure that the sound field/programme you have selected is dolby digital not stereo.(On the amp)
You also need to check on the display that is says DIGITAL not ANOLOUGE, as only a digital input, Optical fibre cable, HDMI, COAX will be a digital signal.
If you are using red and white rca connectors, it is not going to work, as this is an Anolouge signal.

Center channel


Just to rule out the easy solutions, have you made sure no settings changed? Make sure that you didn't accidentally turn off any surround sound settings or turn off the center channel in the MCACC setup or the like (I have the VSX-D814, so your receiver should have MCACC as well). If you're sure no settings changed and the center channel should be working according to the receiver, then it would appear that the center channel amp went out in the receiver. You can either get a Pioneer service center to take a look at it, or if you're comfortable with electronics, I believe you can get the parts straight from Pioneer.

Clark, you MIGHT have a simple problem here. Let's keep our fingers crossed... This problem generally has more to do with the speaker WIRES or their IMPEDENCE than anything else, even though the receiver displays "AMP ERR." (Technically, it IS an amp error, but the source MAY not be the amp!) The very FIRST thing we need to do is check to make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. (Pioneer says 6, but that's not necessarily a good recommendation, particularly if you listen LOUD.) Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker. You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!) [NOTE: Your receiver has internal overload protection systems to prevent permanent damage. On SOME Pioneer models, these can be "reset" but you can't do it yourself. Your dealer or authorized service center must do so.] But, before you take it in for service, there is one more "test": check for shorted and/or mis-connected/disconnected speaker cables/wires. 1) Visually inspect connections at the receiver AND speakers. You might find something obvious! Look for bare wires touching one another. Again, you must look both at the receiver, AND at the speakers. 2) If everything looks okay, then disconnect ALL of the speakers at the receiver; and reconnect and test them one at a time (at relatively low volume.) For example, reconnect the left front speaker, test the system; THEN add the right front, test the system, and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it. Hopefully one of these simple fixes will get you up-and-running. Good luck!

Amp error


I had this exact same problem, it can indicate that there is an impedance mis-match somewhere. i.e. using 4 or 6 ohm speakers instead of 8. However if you unplug the speakers and it is still doing it then you could have a problem with the actual amp circuit.

Mine was doing it with nothing plugged in and had dry solder joints on the circuit board with the two large output devices are. Simply resoldered those and it is fine now.

It had started crackling before it stopped working all together, which would also indicate the start of dry joints or bad connections somewhere.

Regards,

Rolf.
