Subwoofer not working

Recently my subwoofer(Paradigm) has stopped working. When I do the test feature for the surround sound all speakers are active including the subwoofer(works with test signal) however when I try and play a DVD, sat signal there is no subwoofer. I also noticed that the power light for the subwoofer comes on when the amp sends the test signal to it. I have checked all wires and connections and input sources. Please, can you help?

    yamaha receiver?

  • Anonymous Mar 17, 2014

    We cannot get it to connect. We bought a Proscan 2.1 and there is no reset on subwoofer and there is no stop button on the bar, only on and off buttons. We did get a popping sound when we first tried it and had a flashing blue light. There was mention of a green, but we never saw a green light. Is this Proscan 2.1 compatible with our LG TV?

You have to reset the receiver, i had the same problem, works now, it's great, should be in the instruction booklet. I think it was, hold the power button while you disconnect it from the wall, not too clear but check the booklet in resetting system

Yes to Vic's reply. With power off, hold power button as you unplug from wall. I've got an older model (1999-ish), and works for me, so far.

How do I hook up the receiver to the subwoofer to the tv

Here's the Owner's manual ->
There are many ways to connect the system depending on your receiver's outputs and the speakers. Usually, the TV L/R output connects to one of the receiver's inputs. The receiver's preamp sub output goes to the powered subwoofer. The receiver's FL/C/FR/SL/SR/RL/RR speaker outputs go to the respective speakers.

Paradigm pdr80 no sound

If it is a powered sub, the sub power supply may have failed. There might be an open fuse.

Htddw7600, brand new, sub amp is not working, only way to get any bass sound is to unplug the sub cable from back of main amp and touch it on side of sub out port.

You have a very good of the best of SONY..SUB does not get activated automatically especially on STEREO mode.DIRECT STEREO Notes • No sound will be output from the subwoofer.
.your system has Dedicated Power Amplifier for 2 Externally Driven Sub-Woofers (200W RMS x 2) order to activate the sub woofer amplifier you need to make a selection on the surround modes while you are switching the modes of the surround you will see the speaker position on the display of receiver as well..if you do not see the sub woofer it wont be activated..Sound Field Program (A.F.D) is a good example to test it..

How to switch on Sub?

surround and subwoofer may not work if there is an additional graphic equaliser operating.
1. check in your receiver speaker setting ensure your speaker setup doesn not have subwoofer set to NONE. this will block any signal to your subwoofer socket.
2 when you select your surround sound setting setup, ensure you select the speaker mode you want, if there is a multicontrol knob, cycle through the choices
select subwoofer mode and set it to yes.
if you have set-up small speakers S in your speaker settings then it could be that subwoofer is set to yes automatically if you have large speakers L, subwoofer has to be set additionally in the subwoofer setting.
3 test subwoofer on alternative device to test it is working ok
consult manual on enjoying surround sound and adjusting the speaker settings.

Power problem with Paradigm PDR 10 Subwoofer

Yes it can be.You can check it with ohmmeter the impedance should be 4 or 8 ohms.But if you can disassembly the sub its better then you can see and check everything.My guess is that one of the cables on the speakers connector is broken and its just touching the conntact.

Stopped consistently producing sound

Try plugging and unplugging a pair of headphones. The headphone jack in these receivers are flaky and sometimes think there are headphones hooked up even when there isn't. Full repair would require the headphone jack to be replaced. If you don't use headphones at all, you can take the top cover off and unplug the cable going to the headphone jack board and eliminate the problem that was as well.
