Disconnect all your speaker wires from the back of the receiver and turn it back on. If it shuts off, you need to have it serviced. If not post a comment and I can walk you thru troubleshooting. Hope this helps

    It needs to be serviced. Then once it's serviced, check all your speakers and wires for shorts, unless this happened during a storm or power outage. If you don't have a good in line current conditioner/surge, get one. You more thank likely have a bad power supply, transformer, & or chipset.

It is possible that you have switched it from a surround mode to stereo mode. Instructions on how to select a sound mode begin on page 36 of the manual, which can be viewed at the link below.

I turn system on it comes on displays cd vcr sat or other functions then shuts down and it displays powered off


It would appear your unit's self protection mechanism is doing it, to save you from expensive repairs. Please check your speaker connections. It's possible they may be shorted, causing this behaviour.
Good luck!

I have receiver VSX-D509S. Have had it for


Check for a bad ground on the input circuit board. you will need to re-solder them. Remove top cover and rear panel (many screws on rear panel) The input board can easily be accessed and resoldered. you should also check for a bad ground on the speaker jacks. If it is not repaired, sooner or later you will probably need an output IC. good luck.

Pioneer VSX-D509S keeps shutting off


Aside from any intrinsic problem with your receiver, the usual suspects are;
1) Poor receiver ventilation. 2) Very high levels of bass. 3) Shorts in the speaker wiring. 4) A rubbing loudspeaker voice coil.

Overloads all the time under 40db.


Hi Glen. The thing with these new units is that they are so fussy when it comes to frequency range on the speakers. The frequency has to be within the range that the amplifier specifies, or you'll have problems. I suggest that you check your manual to see what the required frequency shuold be and take it from there. I have one myself and love Pioneer

Pioneer VSX-D85OS very loud static through speakers.


Its over heating no cheap fix. But wait if u buy an eternal fan n place it on top or behind it will do the trick. Try blowing on top when static happens n sound comes back on.
