Hi.
I have a Yamaha HTR-3064 5.1 Channel A/V Digital Receiver along with sub woofer model no. NS-SW20.

The issue: The sub woofer turns ON but does not produce any bass / sound.

Checks:
Cable between receiver and subwoofer is OK.
Except woofer all other speakers working OK.
All settings in the receiver are set to support woofer operation.
When the audio cable ( between receiver & woofer) is removed from receiver end and is touched with finger, the woofer makes a humming sound

Can anyone help me to identify the issue here ?

Could be a dead pre-out on the receiver.

Is this a new setup? Did it work before? Did something change?

No set up change. But i noticed that during the subwoofer issue , once it happened that the subwoofer functioned but then after some time same day , there was no sound.

Is there DIY replacement to this circuit ?

Nope. They don't make those system boards anymore.
