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: won't power up; push power button on, hear click in back left of unti, get nothing on front display and no output from speakers; as if unit trying to operate

Disconnect the speakers and see what happens. Carefully examine the speaker cables for unwanted connections (shorts).
Take a clue from when the power problem appeared. Something was moved and made the buzz a (probable) dead short.

SOURCE: Pioneer VSX 818V No Sound

First thing to check is the Speaker Select Switch. It will say, "A" "AB" or "Both" it will be displayed on the LCD screen as well. Second if that's ok, Check the "Direct" switch. If it's on, turn it off. Generally if it's on, you will see a blue light if it's on (most receiver's)

If you still have No audio, hook up your DVD to the "Direct" input and turn "Direct" on. If you have audio then. The DSP chip is probably bad and you should take it to a shop and have them bench it first to confirm. Hope this helps

Crackle problem in right channel of pioneer VSX-D810S Receiver.


I don't particularly know the model, but I can make some generic suggestions.

If you have a speaker ON/OFF switch check the switch. In some of these units there is a speaker protection relay. There are sometimes issues with the relay. Also, investigate for any cold solder connections on the circuit board.

I have seen crackling come from defective components on the circuit board. Finding the defective components can be very involved. This will require the service schematics, and the proper diagnostic tools to persue.

Need to do a hard reset


Usually, a hard reset can be done by unplugging the AC cord from the AC wall socket, and re-plug it back after 15 minutes or so. This is true for most electronic devices. If you wish to make a system reset, you should enter its service mode option, and is really a semi-skilled work. If you wish to get some details; check the site linked here.

I have a Pioneer VSX-305 receiver. I blew channel A speaker outputs by allowing speaker wires to touch while the output was on. Everything else works, including the B speaker outputs. There are only three...


There are independent relays for the speaker A and B switching.Best place to start would be from the relay. When you select A do you hear a click, if not relay is not switching. The circuit involved is a small transistor , a low value resistor ( could be the culprit ) and a shunt diode.

I have a pioneer elite vsx 36tx receiver that quit working. When I turn it on it just hums. It seems like a power supply but not sure.


I have the same receiver.

Do you mean there is an audible hum from the unit, or that speaker output(s) hum?

Let's figure out what DOES work...

Do you get the audible relay click a few seconds after power up?

Does it tune FM?

Can you get the On Screen Display? Settings all ok?

What preceded this? RSVP.

I have a pioneer receiver..vs 812....and sound has ceased to come out of it. It comes on....and switches between sources...but there is no signal coming from ANY source


First make sure the speaker A/B switch is on.
If still no sound, dissconect ALL speakers from the rear of amp.
Now turn on amp and listen for the relays to click in.
One relay will click when you press power. A couple of seconds later, the speaker relay will click in.
If it does, you could have blown outputs, bad speaker wiring, faulty speakers.
If it does not, the speaker relay may be faulty.
Hope this helps.
