I have a pioneer vsx 515. Two days ago I went to turn it on and watch tv, and no sound. I have tried normal speakers as well as headphones (and it recognizes the headphones when i plug them in). ...


Get this service manual and follow it - basically you will have to determine
1 - if the amplifiers get powered
2 - if the amplifiers themselves are good - touch with your finger their input and listen for the buzz on the speakers.
3 - finally if the controller is still functional - if it's not then i'm sorry but there is nothing more to be done for it: the controller is not sold as a separate part, the receiver is dead. maybe you're lucky and you can find another one with failed amplifiers - buy it and use the parts from it.

Denon dra-95vr receiver has no sound out. All


Two things to check. First, the 95VR can be deceiving because it has a "variable loudness" control that some may mistake for volume. The actual volume is controlled by the big up and down arrows on the upper right side. If the volume is turned up, you should see the volume bar graph display show up. If none of the inputs are giving you volume, and the volume is turned up, then try running the output from the processor loop output in the back to another amplifier. The processor out is jumpered to the processor in for normal operation. Missing jumpers could cause a problem also. If there is sound coming to the processor out, then you have a problem with the power amplifiers. Best to refer that to a technician.

Friend turned volume up.. now display/volume died no sound


Sounds like your friend burned out the power amplifier. That would be the only reason none of the channels work. Unless the unit was muted by accident and no one checked the mute function - though I doubt that.

Can a turntable be hooked up to this receiver?


The Aux function is not meant for that purpose.The turntables/Record Players being way too old,now a days the amplifiers do not come with PHONO function that was specially used for playing Records/For turntables. Check if u have a phono function in your amplifier and if not then buy another amplifier with Phono function coz you need a ground wire [that comes out from the turn table] also to be attached to the amplifier and then only you can get a proper sound.

No sounds


Test one speakers at other amp to ensure its working. Amp is going into probable protection mode. Disconnected all speaker and av wires (only power) turn up volume and see if it stays on. If not sounboard or volume function faulty. If on, connect one speaker L or R. Go to tuner mode to tuned radio station an listen for sounds. If sound connect speakers and av cables one by one and test each one on its own until amp switches off, or no volume. Investigate from there were prolem is.

No sound when first turned on.


i have an amplifier ONKIO too and my generation is older than yours but i'm the same probleme and it's normal if you use this amplifier to your speakers. the internal switch must be heat to give a normal sound without distorsion. it's the principal problem of the onkio amplifier but after the quality of thr sound is great
so take the time and be patient now you know you have to start on your amplifier 5mn before use :)
