No sound from speakers, and no response on controller

The other day, I came home to my Bose Lifestyle 50 home theater system not producing any sound, and the controller pad saying “no response”. There was a power surge that day, but it was plugged into a power strip. This particular home theater system is coming up on 18 years old, so it might just have died of old age. I have tried all the relevant suggestions on this guide, and none of them worked. Is it time to buy a new home theater system, or is there other things to try before giving up entirely? Thank you!

To those who are experiencing their Bose Lifestyle 50 with the remote control saying “no response. I got the fix for you.

There are a possible 4 issues that can go wrong with the system.

1) The console cd exchanger,

2) The multiphase coupler

3. The Bose power supply

Or

4) the remote control . Not the speakers.

Start by changing and purchasing a Bose power Supply approx $16.

If that does not fix it than change the multi room coupler. Approximately $85.

If that does not fix it than change the remote control . approximately $75.00

My fix was the power supply and the multi room coupler.

My stereo works fantastic.

Let me know if this helps.

@ajcooke01

can’t give up on iFixit. Of course you tried the reset:

Unplug the multi-room interface power pack for a few seconds, then reconnect it. This allows the unit to reset itself after a power surge or power interruption.

and you tried to re-establish a connection:

If NO RESPONSE is continuously displayed, the link between your music center and the multi-room interface may be broken. To re-establish the link, hold the center close to the interface. Press and hold MUTE for about 5 seconds until you hear a second beep. After about 10 seconds, you should hear two beeps to confirm that the link is established.

Note: The music center establishes a link with the closest multi-room interface.

If you have the multiroom interface you could try to control it through a computer interface. Looks like the Bose Lifestyle all use the same serial commands:

@oldturkey03 I tried all of that already, and there is no computer interface due to how old it is. I looked thru the guide and didn’t find anything else relevant enough to try. I think I might call Bose and if they cannot help I’ll schedule a service call for a local Bose authorized repairman.

@ajcooke01 sounds like a plan just don't throw it out yet ;-)

Don't be surprised if Bose states that this is no longer serviced. I have run into this in the past with Bose. All may not be lost. The key here is the power failure. There may be a component or two inside that were damaged due to the power fail. The service manual does not help much here, but if you can open up the unit and post a few pictures, we may be able to guide you further on things to check.

@abrsvc it is mounted to the wall, so I would have to somehow unmont it. I think the AV receiver just failed because it is older than the speakers & subwoofer itself (23 yrs).

Came across this thread while having the same problem after relocating my Bose Lifestyle 50. I discovered that if I disconnect all/any speaker sets (in my case only Room A) from the multi-room interface, the Personal Music Center remote started “hunting” for a room, flashing A..B..C..D, so I guessed there was a connection between remote and interface. I reseated all my connections, and in my case it seemed that powering off and on the sub woofer solved the problem. All working now! It looks like “No Response” means more than just remote cannot access interface.

Unplug everything from the M1 interface, plug in the power, Press and hold the power button on your Bose P1 remote, or the power and mute button at the same time, I can’t recall. You’ll get a bunch of letters and numbers in the middle of the screen that may be scanning. If not press the arrow to the right beside them to start it. The remote will then flash ABCD at the top middle, plug in your cable to the ABC or D port and interface and it will connect. I think the scans for a frequency code.

This works for me.

Full no response symptoms and no green light on the CD changer. Put an electrical meter on the PSU Jack plug found zero ac volts when looking. Removed PSU and opened it up. Small board in there with spring contacts to the outer part of the unit, I bent the spring contacts and sprayed contact cleaner on the board. Screwed back together, checked on the meter output 14.7 ac volts. Reconnected and all booted up beautifully really pleased; my housewide Lifestyle 50 is up and running! 23 years old and still going strong!
