Usually Humming noises come from frequency interferance.  In this case it is being caused by your input sources.  A smiply solution is to replace the cables and or seperate the source cables away from any electircal cords or sources.

Some kind of ground potential difference between the TV and the AVR or perhaps it's a badly shielded cable.

Considering the multitude of variations you may have connecting the TV video and audio to the receiver it's hard to pin it down, but try removing all cabling between them and that should silence the hum. Add any cable and see if it comes back. Disconnect it. Test each cable the same way. At some point a single cable might be implicated. Replace it.

Also consider routing of any analog audio cable near power cables, the TV or other sources of high voltage and magnetic fields. I have a known problem when my overhead dimmer-controlled track lighting is on. Food for thought.

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.

Humming sound when watching tv,but not when watching dvd's

It wounds like you are getting interference from you tv to the receiver. You can try a few different things here.

1. Connect the tv output into another input on you receiver to see if it isnt the channel on the receiver.

2. Try a different set of cables between the tv and receiver. Faulty cables can give you problems.

3. Connect the cable from you tv to a different device. (another dvd vcr blue ray etc.) This will tell you if its the receivers or the tv.

Audio won't play on DVD - but it will play for CDs

Hello, you can verify that your receiver is working or not. When you are playing a dvd unplug the audio RCA plugs (red and white) from the back of the Sony dvd player. Touch the tips of each of the RCA plugs with your fingertip. You will hear a buzz sound coming from the speaker associated with the plug if the receiver is working\ i.e. touch the red RCA plug tip and the right speaker will hum...touch the white tip and the left speaker will hum or buzz. This will not hurt your system or speaker. If you do not hear the hum turn the volume to 3 or so and wet your fingertip and tap the tip of the RCA connectors. You will hear "pops" coming from the respected channel. I believe your cd\dvd is at fault. Good Luck!

Loud Humming

It's possible a fan or a hard drive is going bad. When the bearings in those devices start to go out they a start making noises like that.
