Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.


Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Pioneer VSX-72TXV wont power up. mcacc light just blinks.. unit does not have a video 2 button on the face.


try holding the "TUNE -" button and the ZONE 2 on/off button and see if it turns on. If its turns on, but turns back off again, you either have a problem with your speakers (try disconnecting them) or there is a problem with the receiver that needs to be repaired.

Twice now my Pioneer VSX-819H has shut down. Can not get any power to it. The first time I'm sure the phono pre-amp caused a surge. I no longer have it hooked up. The servicer said nothing was wrong and...


I found this for the VSX918, 818. Perhaps it's similar.

The power does not turn on. • Disconnect the power plug from the outlet, and insert again.
• Make sure there are no loose strands of speaker wire touching the rear panel. This could cause the receiver to shut off automatically.
The receiver suddenly switches off and the power indicator
blinks.
• After about a minute (you won’t be able to switch the unit on during this time), switch the receiver back on. If the message persists, call a Pioneer authorized independent service company.

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

Pioneer VSX 915 powe off


Had a power surge last night and got the same problem. Unit wont power on and has a blinking blue light on standby button. I found the solution from the service manual for a similar model.

Hold down ENTER and ADVANCED SURROUND buttons.

This resets the DC overvoltage sensor and bingo the unit comes back to life again.

Try this, it may work for you.

1.)Plug the unit into your mains voltage.
2.)Depress the enter and advanced surround buttons (on the front panel of receiver) at the same time for
at least 2 seconds, you should hear the relay tick and front panel should light up.

Blinking Standby


regarding the Pioneer VSX-912 blinking standby light. This is how you reset it; press the "advanced surround" and the " enter" at the same time for about 3 seconds. Make sure you press the ENTER on the reciever (its the one on top next to the small dial) If you press the "ON" instead of "ENTER" it will not work. If an error message comes on and shuts the unit down, just reset it again. This should save you some $$$$. To bad Pioneer did't put this info in the manual.

Receiver just blinks standby will not power on


I have been so bummed, days now I have tried to get my Pioneer receiver to power on from standby with no luck.  We now have our receiver back, the same solution worked for us. Be sure to push the buttons on the receiver unit not the remote.  Thank You! Thank You!
