Question about Pioneer VSX-D510 Receiver

2 Answers

Power out unit turns off temporarily (between 1 second and 5 seconds) or off for good. If I was to have a hunch, it appears to be something like a fan not working and the unit shutting down when over heating, but this is just a laymans guess. the word --powerout-- flashes on the unit and off she goes... anyone??

Re: power out

Try and disconnect ALL of the speakers to the unit. If the unit still does the same thing, this is an indication that there is a fault in the power supply or the main amp circuit of this receiver. If the unit does not do the same thing, try and connect up the speakers, one at a time, until you connect up the speaker that makes the unit shut down. If you connect them all and the unit does not shut down, then there must have beed a speaker wire strand touching. Good Luck

Re: power out

I had the same problem with my amp turning off and then back on in a matter of seconds.
I had no error showing on the screen it was if it was being turned off then back on,i tried the solutions for techs and still had the problem when some one mentioned the power board it was plugged into????
try moving it to a separate power source and see if this works
I know as it did for me and hasn't done it for a week now .
as for the power board it was a cheap arse made in china thing now replaced with a better quality one.
hope this helps some one else and thanks tech guys for the guidance

I have sa-pt350the power led is on but can not turn the unit on , can you help?

Does it try to turn on at all when you hit the power button? Watch the fan in the back and see if it turns for a second or two when you press power.

Not used for several weeks, now will not power up, no response, dead! Any ideas where to start? Merry Christmas to all

There only two reasons for this power fault to this set. Cehck them. If these two are altight, the set need service.
[1] The protection circutary has been activated:
Make sure that all the speaker wire connections on this unit and on all speakers are secure and that the wire for each connection does not touch anything other than its respective connection.
[2] This unit ahs been exposed to a strong external electric shock (such as lightning or strong static electricity): Set this unit to standby mode, disconnect the power cable, plug it back in after 60 seconds and then try to use it normally.
If these does not help you, get this set repaired by the Authorised Service Center for Yamaha at your town. OK.

The amplifier after turn on after 5 seconds go to Video 1 and you can't change to other input, the amplifier don't do nothing if you turn off , the amplifier turn on againyou

The microprocessor may need to be reset. To do so, perform the following;

Unplug the unit from the power source. Wait for a few minutes and then plug it back in again.

Sources of the problem can be from radio interference for example, or I would suspect given the time of year you are reporting the problem, our Sun which is more of a rare incidence but peak times are during the same months as the appearance of the aurora borealis.

Other causes are static electricity.

Dead no power.. checked main fuse, worked fine last night, went to turn it on today and nothing. its a sx-316 not sx-315, I say this because it tells me this is not a valid model#, but sx316 is printed on...

Check the resistance of the primary on the main power transformer, (with power off) should be 1-3 ohms. If open you need a new transformer.

If good turn it on and check for ac voltage (120v) there.

Won't power up; push power button on, hear click in back left of unti, get nothing on front display and no output from speakers; as if unit trying to operate

Disconnect the speakers and see what happens. Carefully examine the speaker cables for unwanted connections (shorts).
Take a clue from when the power problem appeared. Something was moved and made the buzz a (probable) dead short.

My unit has power, but it won't turn on at all.

This means that something is seriously wrong with the unit(blown amp, shorts, opens, etc.) however, you can reset the unit by unplugging the unit, holding the A and B channel buttons on the face of the unit and plugging in the reciever. the display should flash at 1 second intervals. if it doesn't stop flashing on its own then unplug and replug and you should be good to go! good luck.
