How old is your HK receiver? The power supply capacitors can get old and tired, and cause the hum and shutoff. Repair is an option.

Major hummimng noise when sub is connected to receiver.

Is the hum in the receiver-attached speakers or the sub?

Self-powered sub?

How is the sub attached - RCA or speaker-level?

Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.

If it hums with the sub attached, unplug the sub's power cord. Differences in AC ground potentials will generate hum across linked devices.

What sources do you have connected to the receiver? The thing to do is to disconnect your sources one at a time and see if one of those eliminates that hum.

How do I stop the hum coming from my surround sound speakers

You have a ground loop, most probably. Try grounding your receiver by running a copper wire to the screw on the electrical outlet.

Pioneer Receiver SX-750: Getting a loud hum through the speakers

The hum you hear from the speakers and from the unit itself originate with 60hz AC power. They may not actually be related. Sometimes a transformer will hum slightly and unnoticeably. That you're getting a loud speaker hum says there is an electrical leak or a grounding issue somewhere.

Do all sources produce the hum or, say, just the phono? How about on headphones? Try rotating the AC plug. In those days they weren't keyed with one large blade as they are now.

Buzzing/vibration noise from ONYKO TX-SR506 unit

If the unit is under warranty, DO NOT open it up. Bring it in for an exchange or warranty service. Explain that the unit makes noise during use and it will be serviced. This could be as simple as a bad connection in the power supply area and you are hearing oscillations or it could be a defective power transformer. Either case will be covered under warranty so there should be no charge to you.

Keep us posted.
