Facing TV Problems? Ask a TV Technician.
Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems. I'm reviewing your details now and will reply shortly.
Can you please try a basic hard reset of the equipment by unplugging the TV, the Bose and the Cable Box from power for 5 minutes and then plug them back in and let me know if the system resets?
Are you still having the same problem?
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.
Does the bose main unit respond to its own onboard volume buttons?
Thank you for checking.
This indicates a problem with the bose system itself, which is more than just a setting.
There is no setting that would lock out the volume from changing entirely.
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 main unit, not the remote) for 60 seconds4) 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.
You're very welcome, and best of luck to you.
Let me know the results and I'll advise further if needed.
Thank you for trying,
unfortunately, that does confirm that there is internal hardware damage, though that is not surprising to see on a unit this age (it is 20 years old at this point), it is significantly (many times) past its service life.
This would require repairs, but repairs for these units are simply not feasible, there are no parts for them and labor alone is going to be many times the value of the system. While it would be possible to buy a used receiver unit to replace yours, it is probably time to move on to a new system at this point. I can help with repair options if you'd like though, used/parts options, or recommending replacements. Just let me know.
My apologies for the news,
