Pioneer AV Amp Fault

[andy3781]

Hi all, hope someone can me help with a quick fix to my problem... I have a Pioneer VSX-1016v AV Receiver, admittedly its a few years old now but its never been abused and has been well looked after. Problem i have is I appear to have lost output to the right rear channel speaker so my first port of call was to check all cables at amp and speaker end but they were fine. So then i disconnected the cable from the channel and ran just a new short length of cable from the speaker to the amp to see if there was a problem with a break in the cabling somewhere along the way but still nothing! Also i've sent a test tone through all channels and everything works except the rear right. The amp has pre-outs so i took the feed from the av amps right rear pre out in to a seperate power amp and now it works. What is likely to be the problem? A fuse on that right rear channel maybe? Is this a DIY fix? Or is it likely to be something more costly?

PS. Also tried swapping the speakers round to eliminate a problem with the speaker. Speaker worked fine on another channel so thats not it either.

Any help is much appreciated

Sounds like one channel has died on the amp, could be cheap to diagnose and fix, might not be.

Since its a 7.1 amp, are you using it in 5.1 mode, does the amplifier have settings to enable you send the right rear signal to a different power amp channel, maybe one of the used ones.

If you can't do that can you configure it to have left and right surrounds (sides) rather than left and right rears, without the rears configured it is likely to send all the rear signals to the sides if there are no rears present.

Obviously if you are using it in 7.1 then neither of the above will help, in which case, given that you can buy one on eBay at £150, I would either buy another or spend a bit more on a newer amp. Personally unless you are feeling flush I would buy secondhand - a couple of years old, unless you are desperate to have the latest thing.

Am I correct in thinking that you swapped the wires at the amp with your other rear speaker? After checking amp and speaker connections on the faulty one that would be my next action, before resorting to pre-amp output.

I downloaded the manual to see if there was anything obvious.

Have you tried to set the rear speakers as second zone?

manual page 47 said:

You can use the additional amplifier on the surround back channel pre-outs for a single speaker as well. In this case plug the amplifier into the left (L (Single)) terminal only.

I doubt if a single channel has died, as that would likely put the entire unit into protection.

My guess is that there is a dry joint, either on the speaker terminals, or on the protection relay for that channel.

I'm pretty sure the speaker outputs in those are not protected by fuses.

Cheers for the replies...And no I've not got it in 7.1 mode, so I could in theory use the side channels as the rears then? Completely forgot about this as I've never used it! Are the side channels going to be receiving the same signal as what would go to the rears then?... Just tried this out and used the auto calibration with the microphone, only problem is there's no rear speakers being picked up now in auto mode when it sends a test tone through it won't calibrate it properly. C Comes But I can do it manually so obviously this is better than
Paying for a new amp!
