No sound onkyo

[OnkyoHED]

Hello everyone, not sure if this question is in the right spot so forgive me if its not. I just had an Onkyo TX SV-303PRO given to me. There is no sound. The unit turns on and everything else seems to work fine but sound. I have opened the case and checked the glass fuses ( 3 of them total?) and they all looked fine. Any idea what may be wrong? I was thinking you might be able to see if there is any voltage at the speaker out terminals with a multimeter but ive read you need to put a load on the amp? Any help/advice would be awesome. Thank you.

Check if the tape monitor loop is engaged. That is a common thing that gets people scratching their head as to why there is no sound.

Stupid question, how do i see if the tape monitor loop is engaged. Thanks for the reply.

It may be on the receiver's display. Also, be sure that which ever set of terminals you connected the speaker wire (A or B) that the corresponding A or B speakers be activated on the front of the receiver.

On the TX-SV525 model I used to have there were two input selectors on the front panel where one says Tape and the other says Tape 2/Monitor. I believe there is a little red light on the display that lights up when it is in the monitor position. Just press the tape2/monitor while you are trying to play something and see if you then get sound.

One other thing (besides checking the speakers are attached to the correct terminals as Seth suggested), if you are trying to play the radio, you will get nothing if you don't have an antenna attached. Any piece of wire will do to test it out.

Ok i tried the tape monitor 2 button while trying the cd player but nothing happened. I have one speaker hooked up to the main inputs on the back and the main speakers are selected on the display. You know, when i first started playing around with this thing, i pushed the source direct button and i heard the speaker give off one quick crack. Tried to do it again and nothing. As for the antenna, there are four terminals. Which one to use? one is marked 300 ohms, then there is one marked FM right beside it. Then there is one marked AM and one marked 75 ohms. Can i use a coat hanger for the temporary antenna? Thanks guys.

Yes, the auto muting could certainly throw you off, it has done so to me on a few occasions. Even if you don't get any sound from the tuner you can try connecting a source to it if you haven't already.

Well I think we have ruled out common user error, so the tuner is irrelevant. If it gave one sudden pop and has done nothing since I would guess there is a bigger problem beyond my understanding and know how.

Source Direct? I don't recall the SV models having any kind of direct or pure audio type function (but I could certainly be wrong).

I'd try to start with just two speakers connected to the front A terminals and using the tuner. A coat hanger may work but a piece of speaker wire will be about the same - plug it into the FM antenna jack (75 Ohms). Make sure the speaker selection button is on A.

 

[OnkyoHED]

Well one last thing im going to try is the headphone jack on the front of the receiver. Just gotta find some headphones with the big plug! Is the auto mute button what you were talking about with the tape loop situation? Ill go try what youve suggested right now MDS. Ill try anything you guys throw at me! Keep the ideas coming hahahaha

 

[MDS]

The tape monitor is so you can hear what is being recorded and is a feature no longer provided on receivers. It sends the output of the tape 1 input to the input of tape monitor and you'd connect another cassette deck to tape 2. That simply allows you to switch between the playback device and the recording device. When nothing is actually connected to tape 2 out, it appears to be muted because the signal is being sent 'nowhere'.

That may not be the actual problem but it is something that happens a lot. That was the very problem my brother in law had with my old SV525 that is now in his garage.

Ok so i tried the idea suggested by MDS. Nothing happened, still no sound. The display said FM mute = OFF. It says im getting a FM signal, both speakers are hooked up correctly to main, display says speakers are set to main. So i guess this receiver is in need of repair. Anyone know where to get a service manual?

 

[MDS]

http://www.onkyousa.com will have the user manual but I'm not sure if they would have a service manual. Any good electronics repair shop should be able to deal with it as long as the repair doesn't require some part that is no longer available.

I'm a big fan of Onkyo but I'd get a repair estimate first. That receiver was fine in its day but is long in the tooth and lacking features of modern receivers. You could likely get a used or refurbed 501/502/503 for the cost of the repair on the older SV303. Just something to consider.

Yes, you can use a coat hanger to try.
The 300 ohm is an FM antenna with a 300 ohm in-feed lead, those flat separated wires that come on some antenna that comes with the component. You use two terminals. AM at times needs 2 terminals too as they usually supply a loop antenna. The 75 ohm is also an FM antenna with coax feed but you need a different setup with the antenna, a 300 to 75 ohm converter.

If the fuses are OK, you must have something engaged to mute it.

Here’s the Onkyo downloading pdf files for AVR units, I’m not sure if you gave the correct model number because sure had a hard time finding a simple picture of what the AVR looks like in “Google image” sweat bugger all is what I found. So scroll down the link here find the model number and read though it.

Not necessarily, I have had gear before that all fuses where fine and no output (fried resistor). Also, some times a fuse will appear to be fine the only way to be sure is to test it electrically with a volt meter (test to see if it has continuity).

Fried resistor to all channels or another one that is the path to all.
If the fuse wasn't properly checked as you indicated, then it is a different story

please do not forget to maximize the receiver's volume... Some time very small things makes difference

If it suddenly started working this could damage his speakers with volume set to max. IT IS NOT RECOMMENDED!
