Ok, have you tryed to unplug all of the wires from the sub, including the power wire from the wall. Install of the speaker wires to the sub, and plug back in the sub. Also what are the numbers on the speakers and the sub.

If you pulled the cover and only see one fuse, and if it is not blown, then you need to search deeper for the problem. All replaceable fuses on the main board are viewable.

Could be the amp is burned out? Maybe that is why they left it. Not worth the effort to move

Yes turing on the "A" speaker is required for the Onkyo, but that only turns on the 2 front speakers in the "A" speaker jacks.

You may also need to check and see if the Onkyo has a menu selection in the setup menu that will turn on the sub woofer output on the back of the receiver.

I have seen on countless occasions where people just have a hard time finding that sub woofer option on their receiver.

I do not have the manuals for this Onkyo, so I can not tell you the exact way to find it.

I have been repairing surround receivers since they have been on the market and beleive me, you are not alone in this situation.

Sometimes it seems like you need a Phd. in programming or something similar just to firgure out how to set one of these up.

The solution should be in your owners manual, with the problem then being, just where in the manual. Go slowly thru it paying the closest attention to anything about set up procedures.

I have also seen at times where the setup for the sub-woofer is not listed as sub-woofer, but as "LFE" (low frequency effect) . So keep your eyes open for that.

something else, your sub woofer may have an auto turn on. That means it will only turn on if it detects an input signal. Make sure yo uhave the volume up enough on the receiver to trigger that auto turn on if yours has one.

I would like to have been more help, but without the manuals I can only give you general type thngs to look for. These type of receivers are all so different and all so complicated to operate. The days of just turning on a stereo, selecting your source and turning up the volume seem to be over.

Let me know if you need any more assistance from me.

p.s. Very nice system you have, when you get the Kef working I think you are going to just love this system. and Onkyo has the best quality receivers in their price range.

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.

Speakers have nothing to do with spontaneous power ON. It either has a severe and dangerous internal power circuitry issue or it's sensing a remote control command to turn power on and off. Block thereceiver so it can't possibly see any external controllers and see if that stops it.
