My sub is making a "heartbeat" noise even with no audio feed. It is plugged in to a surge protector (I tried two different strips that are working with other components). The audio feed is unplugged and it makes a thump-thump on a regular interval. Any idea? Blown fuse?
You need to check your ground connection. If there is a bad ground there will be feedback to the amp and it will just sit there and loop back with the Thump, Thump, Thump sound. I had to wire my amp's ground all the way back to the negative battery terminal. It was a pain but I have never had a problem since :)
I have Bose sound bar that is thump thump thump it's really annoying any one know why
I've checked all connections
I'm running it through the aux to headphone jack
As the optical cable won't give any decent volume
I'm having the exact same issue after several months of use... Every time I turn on my sub, there is a loud Thump, Thump, Thump, Thump which stays at a constant volume, regardless of the volume knob level in the back. Sounds exactly like someone tapping on a loud microphone in perfect timing. I disconnected my audio signal cable completely from the sub and it does it as well... tried different electrical outlets, and different switch positions on the back... auto or not, it still makes the "heartbeat" sound. It does this for about 10 seconds and then goes silent... when everything is connected to the receiver, it will play perfectly for a while and then at random times will break back into the Thump, Thump, Thump.... It drives me crazy... any solutions? Looks like a quality issue.

A power strip is what's used for plugging in multiple appliances to one outlet. A surge protector is different in that it is designed to prevent electrical surges from too many things plugged in, bad weather or lightening. Usually things like air conditioners with heavy motors are plugged into surge protectors.
There could be many problems with your laptopFirst, check if your laptop was plugged into a surge protector (ex. Power Strip). If it wasn't, a surge could destroy the charger, power supply, or even motherboard. Second, try a different charger. If it was the charger that broke, then try a different one. I have had this happen to many off my computers over the years. If it is fried, take it to Staples, or a local computer shop. I would always recommend plugging computers into surge protectors. Good luck!
It is not latching on to the soundbar transmitter. Is the locked light on the device turning on. Wireless devices are sometimes known to drift. Is the sub silent when the soundbar power is off ?. Even then if its making this sound, the subwoofer amplifier is oscillating at very low frequency. You will need professional help and needs to be repaired.
It sounds to me like your amplifier is getting caught in a loop-- the heartbeat is the subwoofer catching a surge of power from the amplifier. Make sure all of your connections are solid. If they are, try using the amplifier in another vehicle that is already set up for an amplifier. If it does not work, you may need to spring for a new amplifier.
My Onkyo S/W did the same thing untill I unplugged it from the surge protector that all the other A/V devices are plugged into. I plugged the sub into it's very own wall recepticle with it's very own new surge protector. Maybe cleaner power is the answer.
you need an noise filter in line. It's been a few years since I've had a system but I had the same problem. High power amps like the one you have can actually pick up on the electric pulses from your ignition system. I think I got mine at walmart, or auto zone, somewhere like that. Their pretty cheap too. I don't remember how its hooked up, but If you know how to hook and amp up, this should be no problem.
If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
Please try connecting the TV to a different wall outlet and check if that helps.

Try Power Resetting the TV.
Please disconnect the power cord from the wall outlet (for approximately 1 minute), then reconnect the power cord and check whether the issue is resolved.

probably popped a diode in the amplifier circuit. The thumping sound is most likely power feeding back through the circuit, so it will have to be replaced professionally unless you have acess to the proper soldering equipment for IC boards. Hope this helps, even though it is bad news
