Question about Bose Lifestyle 12 System

Bose Lifestyle 12 System bad sound

The system makes what sounds like scratches on a record or bad static noise like poor FM reception when playing radio or CD, it seems like if I wiggle the connector to the bottom of the sub-base unit, or fool with the cord that connects the audio in to the sub-base speaker it fixes it briefly. I can't seem to open the sub-base speaker to see if there is corrosion, and I'm thinking it might be the cord itself, what do you gentlemen think?

Cheers and Merry Christmas,

Re: Bose Lifestyle 12 System bad sound

You can buy a new cord from bose or any palce such as radio shack etc where equivalent connections can be made up to suit with no difficulty.

as for opening the bass box, i recommend not doing this unless it is absolutley the last resort.
the sound will never be the same again and you will end up with a really bad repair that looks bad and sounds bad too.

however if you are determined to do this, let me know firts and i'll tell you how to do it correctly and professionally and very simply indeed. but when youve done this will you know what your are looking at as unless you are an electronics guru with loads of time tools and equipment and hours of time to go to radio shack (again) are you really up to serviceing those not serviceable parts on circuit boards ?

by the tone of you question i think you know already its the cords , go and obtain original replacements from bose or after marklet iones from the internet or get them made to suit locally at any half decent electronics shop.

, good luck

I have a Bose Lifestyle v20 home theater system and whenever I use the radio ( FM/AM ), no sound/music comes out. The rest are fine, but only the FM/AM ones dont work. It used to, but now its gone.

I hope you checked if the antenna wire is connected before reporting this defect.
All modern radios have automatic muting. No sound will come out unless the receiver gets enough signal strength to give you an undistorted sound, so if your antenna wire is disconnected you will get no sound.

I have a Bose Lifestyle 35 Series II and want to know whether it's compatible with a DVD+RW. I'll burn it in a Toshiba recorder, finalize it and then play it on the Bose. Will it play?

Hi This what Bose say about formats

"The Lifestyle® 35 system plays DVD-video in interlaced format, as well as music on CD, CD-R (recordable) and CD-RW (re-writable). The system also plays MP3 files on CD and AM/FM radio. "

So by the sound of this i suspec that you may struggle with DVD/RW. but my best advice is try it.

Bose lifestyle no sound

Hi, best practice when troubleshooting a no-sound Bose Lifesytle system is to first begin with the internal sources (i.e. the AM/FM). Bose Lifestyle system when connected properly (media center and bass box via the data cable) should show a steady green light underneath the bass module. Begin by simply playing AM/FM tuner and try to increase the volume till 45 (normally the sound becomes audible at this level). If the system still has no sound, then try to check if the bass module is steady green. When you see a blinking green LED (slow green) then do kindly check the DIP siwtch (red latch switch with white mini switches) just beside the Light and data connection. All of the switches should be in "ON" position (basically toggled upwards with the arrow marking indication). Before changing DIP switch settings do ensure that the bass module is not connected to the electrical power. after ensuring that all DIP switch are in the "ON" position, connect the data cable firs and then power up the bass module. Then you should see the bass module blink green twice and once you turn on the nedia center, the green blinking should turn steady green. That should sort out your problem.

Also do note tha this procedure applies only to Series II Lifesytle System and does not include the Series IV (with the smaller bass module).

If all still fails, there is an internal problem with the bass module which would require servicing.

Hope this helps!

No sound from my TV!! HELP!!

assume its a bose system 12 (non digital or digital ?)
if you clarify the model of both tv and bose system i will tell you precisely how to connect tv to bose system,

but i must assume first that your cable box is connected to your tv via a scart cable , you must remove sound function from the cable and plug directly into cd5 unit on either auxillary or video input , then turn cd5 unit to that channel to play sound and use bose reomte to control volume (ok)
i would doubt thatthe TV has a audio output, many dont.... also it may be necessary to buy a scart to RCA cable at your local electronics shop or supermarket to completet he task at hand.

if however you are digital.....
make sure you are connectiong bose digital input to a digital (dolby 5.1 compatible) sound source.

sorry if you think i have over simplified the problem !

No sound ? Make sure the audio input cable is connected to the music center FIXED outputs, the black connector is fully seated in the music center SYSTEM CONTROL 1 jack, and the multi-pin connector is firmly seated in the Acoustimass module jack. ? Turn the music center off for ten seconds, then on again, to reestablish communication between the music center and the speakers. ? Check the connections for any external components. Make sure to select the correct source for the desired input. ? Check the speaker connections. ? Be sure the CD is placed correctly, label-side up, in the music center, and the cover is closed. ? Increase the volume. ? Check to see if MUTE is lit in the display. Press the MUTE button on the remote to unmute the sound. ? Disconnect any headphones. ? Connect the FM and AM antennas , and last but not least. Make sure there is power going to the remote speakers or the unit will not communicate with them. Good Luck
