Question about Onkyo HT-SR700 System

2 Answers

Power, but no sound coming from my speakers, checked fuses.

It was working fine then turned it on one day and I had no sound coming out from my speakers. It show power when I turn it on but I get no sound out of my speakers. Do the speakers have fuses too, they are onkyo too. If this continues might have to use it for road kill.

    I have the same problem as youngcity with the same device the HT-R520. I have power, but no sound. It worked after being stored because of that problem, but after hooking up an s-cable to the amp it quit. 6 months ago it happened I took it apart blew out all the components, checked all fueses, relays, and all the other thing-a-ma-giggs and found nothing.

No sound coming out but I can make the power stay on if I hit bypass fast but if u turn any other speakers/surround sound on the relay kicks and powers off


Hi Michael

FWIW, the manual for your system can be viewed/downloaded here
http://support.radioshack.com/support_audio/doc66/66651.pdf

You mention that the fuse is good. It's there to protect more expensive electronics, so that's good.

At the lowest levels, relays kicking like that mean that something is drawing more current than the system wants to supply, which tends to lead to heat, distortion, and damage. Too much current draw, in turn, will usually come from less resistance than expected on the outputs. The manual lists the 2280 at 80 W/channel at 8 Ohms on each speaker. If you have the factory speakers, you should be fine. If you have other speakers of lower impedance, they could be over-drawing current to drive them.

You could also have a short in one of the speaker loops. This could be from a wire inadvertently gapping the + / - gap at either the receiver end, or the speaker end, damaged insulation on a wire that lets the red and silver wires touch, or a straight disconnect from a speaker leaving bare wire tips touching. That's basically zero ohms, and will likely pop the breaker quick. if they are close, then the gap might be intermittent., Trace each speaker wire end to end and make sure all connections are tight, separate, and all insulation is intact.

After that, I'd likely be jumping off into a rabbits hole of possible component failures - say a short inside a speaker. If you have another amp, you can try the speakers and wires, one at a time, to verify they work OK and dont' blow more relays. If the speakers and wires all check out, you can disconnect all the speaker, put in a headphone jack, and see if you get sound now and can keep the power on. if it still pops, then it's the amp itself and you'll need a repair person with more specific chops for the gear than I have.

Hoping this helps!

Power will not come on. Indicator light is off as well.


Sounds like you have a fuse problem. Check the fuse and if that;s not it then more than likely you have Problems in the power supply. It should have a year warranty on it. I would take it back.

I have a JVC TH-C30 an it turns on but no sound. Left it off for a day then tried again.....nothing! Changed power fuse....nothing! What else could I try to make this work?


If something turns on the fuse isn't blown.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

Speakers buzz with no sound


Is this only with CD, only with THAT CD, or with nothing in particular selected or playing?

Check all connections for tightness as bad cable shield connections will let emitted noise into the system. Ditto for signal or speaker cables routed near power cables, TV's, other electrical sources.

Sometimews reversing the AC power cord polarity can resolve buzz/hum.

Is it possible to change a fuse


the 1.0 A is the amps .
bose are very secretif when it comes to the the Head deck .
if you are keen on opening the head deck and try to look for a fuse , go ahead but i would suggest to doe the following , place a set of hear phone in the jack output and turn the music on .
if it does work , you may have blowned the main speaker output .
if it does not work at all , you may have fuses may have gone but check inside the system as next to the speakers output you may have a fuse in line hidden .
Please make sure all power is diconnected prior to opening the device .
best of lack and let me know how you go

No audio is coming through my speakers


If the receiver is actually powering up but you are getting no sound, there are few basic things to check.

Check the audio connections on the back (speakers AND inputs) to make sure they are tight at both ends and undamaged. Go into the setup screen for the DVD player and make sure the audio settings are set for PCM output and that you are using a digital or optical audio cable. Then make sure you have the correct function selected on the receiver to match the inputs. If the receiver has a speaker test function, use it to see if there is any output from the speakers. Finally, make sure the volume is turned up and the mute button is off.

Otherwise, the amplifier may be faulty

Very low sound from all channels


Without a model # it's hard to say what you have or what the problem might be, but since you said "in the day" I'll assume it's old enough to have a tape monitor function... Make sure Tape Monitor 2 is not on. Also make sure you are on the correct A/B setting.

RCA RT2250R P.O.S. no sound


The blinking speakers mean the unit is waiting for an input. It could be that the input section is faulty, but I need more details.

What input is being used?
what speakers are connected and to where?
what is the audio source?
