Hi, I'm Nathan.
Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.

Ok.. Waiting
Expert:  Nathan replied 9 months ago.

Can you tell me what you are using for the sound? You mentioned am/fm, so that wouldn't come from the tv, are you using a stereo system?

Customer: replied 9 months ago.
Its a Bose System.. Am/Fm Cd/DVD.. Tv is all hooked together with Time Warner.. TV is perfect and can change channels w/o problem.. No sound from ANYTHING..
Expert:  Nathan replied 9 months ago.

Can you please check that the cords to the "acoustimass" (subwoofer) module are all connected (power cord and link to the main AV unit)

Customer: replied 9 months ago.
DONE!All cords , everything plugged in and in place.. Just remembered this happened before.. We thought then it was vibration but don't recall how it was remedied..
Expert:  Nathan replied 9 months ago.

So did that resolve it?

A loose cord/connection is really the only reason this would happen, other than an internal hardware fault, if it happens on all inputs.

Customer: replied 9 months ago.
I think it was a lose cord before on the subwoofer..We have checked everything.. Like I said.. Tv picture is great.. Bose screen reads perfect..
Customer: replied 9 months ago.
What do you suggest I still have no sound
Expert:  Nathan replied 9 months ago.

Thank you for checking,

that does indicate a hardware defect within the bose unit, any button pressing by guests is likely just coincidental.

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 significantly past 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

2) Wait at least 1 hour (60+ Minutes)

3) Press and hold the power button (on the set, 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 bose sytems are generally not considered repairable and the cost of repairs will usually be as much or more than a new system.

Depending how you’d like to proceed here, I can help with finding parts, finding a repair shop, or recommending replacement options. Just let me know.
