SW15 Sub - "Auto" Green - "On" Red

Turned on sub and found that the "Auto" switched position illuminates a green light, while the "On", when switched, illuminates a red light.  No sound is coming from the sub.  I suspect a blown circuit board.  Also fuse is good.  Help!

Looking for help diagnosing circuit board on sub12 venue series. It powers up red led, and goes green when sensing input. Power supply and speaker checks out good. Any suggestions? Thank You


the change from red to green is simply the auto sense of the input signal happening . have you ck the simple things first , like the volume control (im sure YOu didn't touch it , but maybe someone else did) , did the input jack sustain some internal dammge that might not be seen from the outside ? how did you ck the speaker ? did you sub it out with another known working one (doesn't have to be same size to try it) ???

JBL PB12 will have loud thump or pop!


First try to find the source of your problem. The easiest way would be to try your sub with a different audio source to see if the problem still occurs but is sounds more like there's a problem with the receiver.

I have a Mirage Prestige S8 subwoofer. 4 years old. Suddenly nothing....not functioning. No change in usage or location. Any ideas?


Check the status indicator - The LED found on the front panel should be illuminate in blue when the subwoofer is functioning. If the unit is in Auto mode and is not receiving a signal, the light will remain off. Try setting the power switch on the back to ON if in the Auto setting. Post back the status of your LED.

AR SW-30 subwoofer doesn't switch to standby mode when off


Disconnect its input cable to see if a true lack of signal lets it go to sleep. If not, it has a bug. Otherwise, you probably have some sort of signal present on the sub cable.

No Sound


This might very well be a fuse - check by setting the sub woofer to "On" to see if it powers up. If it does, there may be a problem with the sub woofer audio cable(s) or connection(s).

Don't forget to check for a tripped circuit breaker or blown fuse on the stereo's speaker output. If your sub is connected to a low level output - this shouldn't be a possible cause - as circuit breakers & fuses are usually on amplified (high level) or speaker outputs.

Another possibility is that the settings of the stereo has been changed from a *.1 system to plain stereo 2.0 or some other setting that disables the LFE (low frequency effects) or sub woofer audio output.

Infinity tss-1100 sub problem


hey buddy, I have the same system, and although I haven't experienced it on this one, I had the Harman Kardon equivalent to the TSS-750, and the sub did this same thing. It was a loose RCA connection, and, as I was well outside of warranty, I took the amp out of the back and just re-soldered the connection myself. It now functions flawlessly for my bedroom setup. I hope you get it all worked out on your system! I can't imagine using this awesome system without its deep notes!

Some basic trouble shooting is required here. First you need to see if it is a problem from your source or the sub. Try a different source to the sub-woofer and see if it changes the response. If still nothing on the sub, then most likely there is an issue with the amp or driver. Check to see if there is a fuse on the sub, if so, it could be blown. There could also be an issue with the auto switching circuit on the subs amp, in that case, it would need to be repaired in the shop. But before that I would check all of the connections to the sub, and also to the driver in the cabinet. If everything looks good, then put some type of source directly to the woofer to see if it works, if you get sound, then looks like the amp has a problem. Again a repair or replace issue.
