Question about Pioneer VSX-D509S Receiver

1 Answer

"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 Pioneer VSX-D509S has been doing the same for over a year now and at this point it pretty much shuts down all the time within seconds so I quit using it. The only difference with mine and Mojo 3's is my display constantly says "POWERSAVE" when it shuts down. It will also turn itself back on sometimes but it always says "POWERSAVE" (not POWER-OFF) Is this the same thing or different?

    'POWEROFF' comes on and immediately it shuts itself off, it will not even stay on for 3 seconds. I tried holding down the power button for 10 seconds and it still shuts down without allowing any kind of reboot. I dont even have any speakers hooked up to it.

    My Wedge Radio turns itself off and back on again at random (the backlight goes off and the unit does not display the time). When it comes back on, I have to reset the clock date and year. Any ideas?

I have a sony bravia kdl-37v5810. sound on loud no picture buttons dont work on set or remote have to unplug to switch off.

Two pieces of information:

First thing to try is unplug the set and a box or receiver if you use them for several minutes from power, then plug things back for power and see if that helps.

Second, Sony is one of the few companies who uses the same access code to reset all their sets for the last 20 years, if it comes on and responds to the Sony original remote you can try that,

set is off, Then with the remote Display, 5, volume up, and power.

If set comes on you should be in the service menu---do not by accident touch any buttons randomly : what you want to touch is 8 (reset or write should appear on the screen in red, then hit enter and the word should change to green and the set shut off.

turn back on with remote and see what happened or not.

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
