Need tech advise - LIFESTYLE 25

Yesterday Lifestyle 25 worked perfect. Today only sound from left front speaker. Control head seems OK, lights up, can change stations & inputs, good stereo sound in headphones. Problem in power amps section ??? Where can I get a service manual? Suggestions? I have not opened up the PA module yet.

Hey DangerousDan,

 

Thank you for your post and welcome!

 

I'm sorry to hear of the issues you seem to be experiencing with your Lifestyle 25 system and the audio. I'll be more than happy to help you! 

 

I do not recommend opening the module. I would recommend starting simple and checking all the connections. I have included a LINK HERE to the manual to assist you with making sure all the connections are in the correct place. 

 

 If this is all correct and you are still experiencing the same issues, I would recommend trying the other satellite speakers in place of the one that is correctly producing audio. This should help us to determine if it is the speakers causing the issue. 

 

I look forward to hearing from you!

Re: Need tech advise - LIFESTYLE 25

Do you know where I can obtain schematic for the Lifestyle 25 powered speaker system? Specifically I need the power amp. Also, is there a tech at Bose that I can call and speak to regarding repair?

Re: Need tech advise - LIFESTYLE 25

Initially, I did contact Bose service and got no where because this unit is no longer sold and they would not send me any documentation implying that they did not provide them to the consuming public because they were not smart enough to read them. I have the Service Manual PN 194382 Rev 1 and Trouble Shooting Guide PN 199401-TG1 but these do not match perfectly with the unit I own. These are for the AM-25/30P II. Therefore I must have the "Series I" (series one) and not the II. I need a schematic of the power amp and DSP board (within the Digital Bass Module. Can you help me? The answers I am getting seem to be "boiler plate" so I really need to talk with a technician. Can you put that together? Regards, Dan

Re: Need tech advise - LIFESTYLE 25

Personally, I would sell the working components on eBay and purchase a new system.  If you aren't interested in doing that, why not purchase a used replacement component on eBay?  Looks like they have listings for almost anything you might need.  There is no way Bose is going to be part of you doing a repair yourself.  That would open up a huge can of potential liability issues.
