SOURCE: Replacement parts for Infinity TSS-1100 subwoofer.
Same issue here. 3 years without problems then the burning smell and finally it died. I've removed all of the screws from the back but haven't had success opening the unit. Anyone figure out a solution to fix the circuit board?

There's a seller on eBay who has a fixed-price repair for it...

which may be cheaper than sourcing the part and getting it installed it yourself.

Try hooking the speaker into a different input device if the problem still occurs most likely the built-in amplifier is shot & has a bad capacitor or other component. You can also try remove all RF emoting devices far away from speakers like cell phones, devices with motors like fans, or any other wireless device or least turn them off. Sometimes other devices on the same A/C circuit can cause interference, computers, tvs, etc.
TIPDon't use a normal cable or satellite program for this; you're about to disconnect the cable that provides the audio and video for your cable/satellite feed.
WARNINGOddly enough, this solution (surge protection) can sometimes increase the humming.
WARNINGIt is unsafe to use a two-prong to three-prong "cheater" plug on the subwoofer power cord to solve the hum problem. Even if the subwoofer came with a cheater plug in the box, it's REALLY not safe to do. Don't do it.

Page 44 - read about "humming".
If you have hum on the sub, is it there with and/or without the input cable attached?
Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.
