Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems. Please note it can take me a few minutes between replies, so please be patient.

Expert:  Aric replied 10 months ago.

Please tell me what model Bose you're referring to here - they make many different systems.

Also, what is connected to the Bose (TV, cable box, DVD, etc.)?

Customer: replied 10 months ago.
Direct TV and TV model PS48
Expert:  Aric replied 10 months ago.

Thanks for the reply. So this system has a built in DVD player as well as can receive sound from DirecTv and the TV.

Please follow the steps below:
1) Shut the TV off, and then disconnect the SAT box (DirecTv box) from power (unplug its power cord).
2) If using an HDMI cable, disconnect and reconnect the HDMI cable on both ends when the cable box is unplugged from power (make sure it's secure on both ends).
3) Plug the DTV box back in and give it a minute or so to reboot.

This should restore the sound. However if it does not, then please try another source- such as the DVD player in the Bose and see if that has sound. This tells us whether or not the Bose, or the cable/SAT box itself is causing the problem.

Please send a reply back with the results once you try that reboot.

i will but nothing has sound
Expert:  Aric replied 10 months ago.

Please clarify, I'm not there to see/hear what you do. Did you try the Bose built in DVD player please?

Expert:  Aric replied 10 months ago.

Does the Bose DVD player have sound? I stated above that testing that tells us whether the Bose has a failure or the DirecTv box is the root cause. Let me know please.

Customer: replied 10 months ago.
Have tried CD Radio and TV and nothing has sound
Expert:  Aric replied 10 months ago.

That means the Bose has failed, there are no settings on the Bose that will cause it to lose sound on all sources.

Please unplug the Bose from power, then disconnect and reconnect the umbilical cable between the main unit and the subwoofer making sure it's secure. Plug the Bose back in and power it up. Check once more for sound.

Are you still having the same problem please?

Customer: replied 10 months ago.
tried everything you said and still does not work
Expert:  Aric replied 10 months ago.

Okay, all I can provide are the steps on a user level you can take to correct this. Beyond that, you're looking at hardware failure, which is not uncommon in the 10-12 year range. The last ditch effort to get the Bose to reset is to leave it completely unplugged from power for 60 minutes or more in the hopes the processor resets. Beyond this, the system does require repairs in order to function properly again (with sound).

In this case you would need to contact Bose Service, as they are the only ones that repair their systems:
