Question about Onkyo TX-SV444 Receiver
I have a Onkyo TX-SV444 receiver. 4 years ago I bagged and boxed it, it was workinig fine. Fast forward 4 years and I unpack it, wired up the speakers and hit the power button. Unit powered up but there is no volume. Yes, it does respond to the volume knob but it sounds like a headphone speaker from 10 feet away. I am more than confident that the wires and knob selections are OK. Do you have any recommendations...Thanks

Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
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 'naked'. 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.

SOURCE: Onkyo TX-SV444 problem
Hello. If the wires have touched, your amplifier probably has what's known a DC Offset, meaning a damaged amplifier. You will need a qualified audio tech to repair this, as this type of forum is not designed for detailed step by step repair.
