Pioneer vsx-519 no sound from center and surround

This is receiver thermal going in protect issue and has no bearing to your sub, The sub has its own power amp and not supplied by the receiver. Thermal module may be bad. See a tech.

Yes, both receiver and tv have optical/digital connectors, or alternatively, the S-video connector. The Pioneer will decode the compressed 5.1 signal coming from the tv unit.

If you do not have a center channel speaker connected, then in the reciever setup menu for speakers, there should be a selection for center channel that says something like either yes or no. I'm guessing it says yes. Then you need to select "no" so that the circuitry will direct sound specified for the center channel to be reproduced through your front speakers.

Rear Surrounds are not supported on this unit, they would be the 6th and 7th channels in a 7.1 rig. I think you mean Surrounds (channels 4 and 5 in a 5.1 rig).

Lets ponder: How is there any relationship between Surrounds and your separately-amplified Subwoofer? I don't see it, unless you inadvertently chose OFF for the Sub definition when you were in the Speaker selection menus adding the Surrounds. Look again.

If it's under warranty..get a new one.
It's an internal breakdown ...tech service only.

Yes. It is 5.1 surround. There are 2 front channels, 1 center channel, and 2 rear channels which comprise the "5" in 5.1 surround. The pre-amp output channel for a sub is the ".5".

You can hook them up either way, the banana jacks are good for hooking two speakers to one terminal (ie one through the botton, one banana) but the electrical connection is the same either way. Sometimes the banana capable jacks are on speakers A and speakers B, and the surround don't accept banana plugs, your stuck with how your reciever is wired.

go through your mode channels to put it on surround sound

Just to rule out the easy solutions, have you made sure no settings changed? Make sure that you didn't accidentally turn off any surround sound settings or turn off the center channel in the MCACC setup or the like (I have the VSX-D814, so your receiver should have MCACC as well). If you're sure no settings changed and the center channel should be working according to the receiver, then it would appear that the center channel amp went out in the receiver. You can either get a Pioneer service center to take a look at it, or if you're comfortable with electronics, I believe you can get the parts straight from Pioneer.

I got the same issue. But, I go ahead hooked it up two banana plugs on teh VCR outlet. It works fine on my Cerwin Vega Sub.
