My Pioneer VSX-519V shut off after I setup my surround speakers ,I did a last test to be sure they were set correct ,I heard a loud pitch come from each speaker rather that the softer shhh sound ,my amp then shut off and wont turn back on ,I opened the cover found one fuse it is ok ..any thoughts...

The owners manual says that if the speaker wire touches the chassis it will automatically shut off. You can replace it for about $40 on E-bay which is probably less than it would cost to have it repaired at an audio shop. Search "Pioneer VSX-519V" in Bing or Google and see your options. They also have manuals available for this model. Good luck!

try setting the front speakers to 'small' in the setup menu. some models of pioneer receivers disable the subwoofer output if the fronts are set to large

google your wire harness for ur car and make sure your connections are tight and hooked up rite

Sounds like a bad speaker or speaker that is being over-driven.

You guys mentioned the reset via the front panel, and I tried that with this very same issue on my VSX-822-k and it worked!
thought I would post the instructions for anyone else that lands here:
Reset the main unit if the receiver is generally not operating correctly. Switch the receiver into standby mode. Hold down the "BAND" button while pressing the "STANDYBY/ON" button for about two seconds. When "Reset?" appears in the display window, press the "AUTO SURROUND/ STREAM DIRECT" button. "OK?" appears in the display window. Press "STEREO/A.L.C." to confirm. "OK" appears in the window. The system has been reset.

Hello,
To get sound out of your surround speakers, first off go through the receiver setup and make sure that is correct. Also, usually the best soundfields to use for sourround sound is PLII Movie or dolby digital. Next , make sure the source you are viewing is capable of outputting 5.1 sourround sound. Lastly, it is a good thing to remember that sourround speakers are only intended to reproduce sound effects. You certainly can override it so that all speakers play full range audio, but that is not the intention.
Good Luck

It's a receiver, not a tuner.

Clearly something is overloading it or forcing it into self protection.

What else is drawing power from the same souce as the receiver, or from its convenience outlet. There IS a limit to how much current it will support.

Try checking the speaker connections and their impedance to make sure it's not unacceptably low.

DSP modes usually act on ANY input source, including stereo. Are you saying you have no surround speaker fucntions? Get in the setup and define, then adjust them.

You speakers are out of phase. Check to see if the polarity is correct on the receiver and the speaker. Positive (red) with positive, negative with negative (black). Also check the impedance of the speaker, it should be located on the back of the speaker measured in ohms. Make sure that your receiver matches the impedance of your speaker. You can find this in the settings of the receiver.

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.
