Hello, I’m Nathan, and I’ll be assisting you today.
Sorry to hear that you’re having trouble with this but I’ll do my best to help you out.
Unfortunately, the issues you are experiencing are symptomatic of an internal hardware defect, meaning a faulty amplifier in the acoustimass module (subwoofer) or control board in the main unit, though there are many possible failure points. This issue could be a manufacturing defect, but is also often caused by a power event (shock/surge, prolonged over/under voltage condition, etc).
This could also be the result of age related wear and tear; as a 2005 model, that type of failure wouldn’t be surprising. This system is at nearly 3 times its service life at this point.
There is one step you can take here, both as a possible fix, as well as a diagnostic evaluation:
1) Unplug the power cord from the outlet, for both the main console and the acoustimass module (subwoofer)
2) Wait at least 1 hour (60+ Minutes)
3) Press and hold the power button (on the main console, not the remote) for 60 seconds
4) Keep holding power button while plugging back in, and for another 60 seconds after. When plugging back in, go directly to the wall outlet, bypassing any power strips or surge protectors.
If this reset process does not work, it would unfortunately confirm an internal hardware failure.
This is something that would require repairs to correct; however repairs for these systems is simply not feasible. There are no parts available and the components are highly proprietary and not interchangeable. There are no factory service options, and labor alone will usually exceed the value of the system. Replacing the entire system at this point, with an updated model with current technology and a fresh warranty would be your best option.
I can help you with repair options, or recommending replacement options, if desired.
My apologies for the news,
