Question about Pioneer VSX-D509S Receiver

"POWEROFF" display comes up randomly

PLease help. FOr several years now my receiver has been doing this thing where is turns itself off at random times. Sometimes the thing works for 6 months with no problems, and then it comes back. It has done it while attached to all different speakers, so I don't think it is a bad speaker. Playing with the speaker connections doesn't seem to help eihter. It also isn't dependent on what decibal it is at, or what input setting it is on. Sometimes it will click off, then on, then off, back and forth several times with 15 seconds or so before it settles on one or the other. So it doesn't say "OVERLOAD", just "POWEROFF". What can I do? Ususally it just goes away after a while, but this time it seems to be sticking around. Thanks.

My Yamaha RX-A1010 turns on and shuts off by itself on occasion. It also randomly switches between inputs by itself.

Your receiver may be detecting random signals from some other source. Infrared is pretty much line of sight but RF can come from anywhere.

Why would JVC 8010 optic digital randomly malfunction?

I don't know if this helps but, if you have your bluray hooked directly to your tv some times TVs can have issues sending the proper channel to audio out to the receiver. You should always connect your bluray and other devices directly to your receiver.

if that's not the case,
Try turning the tv speakers back on, test the bluray hooked directly to the tv and see if things work flawlessly just with the tv and bluray.

If they don't there may be something just wrong with the cables.

If they do work flawlessly then there may be something wrong with the receiver.

If you already had your bluray connected to the receiver, I would still try direct to tv test and swapping cables.

The randomness leads me to think cables. But you can rule them out by testing directly to TV.

I hope that helps

When we watch football, we can't hear the refs on the field. Also during halftime we can't hear the music. Some random things get cut out.

do you have a center channel speaker hooked up? Most voices come through the center channel. I would imagine the surround processor would put the refs on the center channel.

When i play my PS3 game the receiver shorts out and shuts off at random points...also does that when watching a movie will just randomly turn off and short out


Cutting out on the sound is usually a blown IC on the circuit board of the unit itself. This can also result in the player turning off randomly.

Take you receiver to your nearest electronic repair shop, let them replace the blown IC.

This should do the trick.

Kind regards

My receiver clicks on a off randomly.

Hello Fixya customer,

Thank you for your question.

Are you getting on the display, possibly a "P" or "Protect" that indicates it is in the protect mode?

Hitting the top of the receiver indicates a possible intermittent component or board connection. The receiver will shut down when the Microprocessor receives various fault conditions, including shorted speaker and wires, but if it develops an internal fault it will also shut down to protect itself and the speakers.

Remove all speaker wires and inspect th terminals for any stray wires shorting the terminals.

If it still shuts down, then a professional servicer would be required.

Thanks for using Fixya, and if I can help you further, please let me know.

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.
