Question about Bose Lifestyle 12 System

Bose Lifestyle 12 "no display" fix

My unit is around 10 yrs old and have not had display for many years. I have the unit behind TV sitting on the subwoofer so not having display is no biggie. I've always used the remote with no problem for TV/movies on aux, radio, and cd, but would like to fix if possible. I think my problem is a bit more than just "no display". If I remember correctly I don't think the panel buttons work either... Was that the same case with your unit? Can you be a little more specific on the condenser replacement procedure than "its down in the lower left corner...." Is it soldered in? Can you provide part number? Better description of exact component location. Can you get a replacement somewhere like radio shack?
Thanks

Bose products are highly proprietary. If they have non-standard connectors from the amp or in the speakers I'd take that as a clue they're NOT compatible with other manufacturers' products.

Bose Lifestyle 12 version 1


Hi, The dead display is possibly down to a capacitor problem, see fixes already covered by me, it's a 33uF capacitor either on the display board or if a newer unit on the main pcb, these cost less than $1 there is only one just change it.
The no audio may be a simple fix, do you have sound from the head set socket?, if yes then look for one of my other fixes on changing a resistor near the control socket, if no then I need to have a think... If the unit has no sound or display after changing the capacitor it could be a power supply fault. Fix the display first and let me know.

Lifestyle 12 speaks - new HDTV


mount to wall, brackets available to purcahse on loads of on line sites. and from bose direct cost 5 dolurs to 50 dollars eack depending how fancy you want to be.
would recomment also distancing the left right satellites as you will be amazed how much improvement in sound is gained from a well defined centre channel.

also if you want to be really smart. its really not necessary to see the centre satelliet and it could simply sit of the stand behind the tv. with no problem. plus you could use the tv audio input to make the tv as a centre channel. you would be surprised how well that works. make sure you disable the tvs steroe function or your surround sound will not sound too surround....

finally if you have lifestyle series II make sure you conect the 5.1 input to the bass box to your tv. and get rid of the bose cd player , put it out of sight, and loose the remote. will work even better than it did before !

Bose lifestyle 12 music center display inop


My display has not been working for years. Replaced c17 cap wich was 33uF 63 volts on lower pcb board( only one on system) . Old cap was good so this was not the problem. Replaced c16 wich was 100uF 25 volts with a 100uF 63volts. Display works, old cap read low. Both c17, and c16 are located on the lower left hand corner of the larger pcb looking from the front of the unit. Hope this helps.
