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

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.

SOURCE: My pioneer vsx-519V-k amp won't turn on. Just

Have you checked within the set, the fuse and if the standby circuit is working. thre could be a failure of this sub votage which is required for the switch on of the main power. If you do not have any standby indication you must check this section, however if you arre getting the standby you would have a failed output or a shorting that is triggering the error amp to swtich off. If you are familiar with the circuits you can check but I would suggest that since you will need more experience to look into the main board for tracing the fault. In such case check for the service centre nearest to the place you are in using a google search for Pioneer - Audio systems- sevice. Helpful I hope. Good day.

Try holding the "advanced surround" and "enter" buttons and see if it turns back on. If it shuts off again, disconnect all speaker wires and try it again. If it stays on, you have a bad speaker or wire. If it still shuts down, the amp is blown and needs to be repaired.

My component pioneer vsx-518 has no power, what is the main reason and which item will i check?


• If you have a multimeter, check for DC outputs on the power

supply regulators, there could be some


• Or check for cold solder joints (if you can't find any)

diodes, capacitors or regulators

on the power supply.

• These could be just a power supply problem, main amp or both


Let me know if you need further assistance!

Can't get it to turn on


If you are encountering power problems with your printer, please go through the following checklist:

  • Make sure the power cord is plugged in securely and directly to the power outlet. Power surge protectors can draw power away from the printer.
  • Disconnect the power cord from the power outlet and the back of the printer and then reconnect it.
  • Check the power supply box (if there is one) to see if it is warm or cold, as there could be a defective power supply issue.
  • If there is access to a voltmeter, test the power supply to ensure that it registering the correct amount of voltage (most Lexmark printers have a 30Volt output).
  • Make sure the correct power supply is connected to the printer.

> bad power supply

Try an ordinary lamp in the wall-socket -- to make sure that a circuit-breaker inside your home has not "tripped", i.e., no power to anything that plugs in.

If there is an on/off switch beside where the power-cord connects to the power-supply, switch it to the "off" ("zero") position.

Unplug the AC cord from the power-supply.

While watching the fan inside the power-supply, and/or watching the fan on top of the CPU, plug-in the AC cord. One of the fans may "twitch", if there is power.

Flip that rocker-switch to the "on" ("one") position, and see if one of the fans "twitches".
Also, look on the motherboard for a small lamp -- it may go on if the AC power-cord is connected,
or may go on when that "back" switch is set to "on".

Try a different power-supply. If still nothing, then it's your motherboard that got "fried".

I recommend you replace the switch mode power supply. These power supplies have dangerous mains voltage inside the unit and you should not try to repair if you do not have electronic knowledge.
The cost of a 500 W ATX power supply should be approx. $100.
It is not difficult to swap out the power supply, make sure you have the power connectors are the same as the old power supply.

Showing 121: fatal error


It is not exactly "fatal", it is related to LSI power supply or disturbance in it communication with high-voltage LSI chip, try this solution first:

1. switch off the printer and remove cord from power supply, remove network connection as well.
2. switch printer on (without power!) for 20sec, switch off
3. connect power supply, and switch printer on
4. connect network cable

If this operation did not clear the error, unfortunately you need to service the printer.

Hope this will help to solve your problem, please leavenote how did it go.

Power overload


That is a good thing, your receiver is going into "protect mode" that means the receiver is shutting down to keep from damaging delicate internal circuitry, it is sensing a speaker bottoming out or some other electrical "short" that could be damaging!
Also could be from over driveing the amp and then it starts to overheat thus going into "protect mode".
If your speakers are "clipping or distorting" turn it down, you are going to ruin your amp. Good luck !
