SOURCE: bose acoustimass 25 subwoofer has no power

Honestly speaking you should probably not work on this unit yourself: "There are no user serviceable parts inside"

Even if you are an accomplished Electrical Engineer Bose will not provide the required schematics to troubleshoot and repair this unit.

Are you still undaunted . . . then if the case is the original LS-25 series, there is a hidden catch at the end of the cover furthest from the input connectors that needs to be rotated (until a plastic tab is sticking out), which you can do with a flat bladed screw driver, and you also need to remove a few screws from the bay where all of the connectors reside. Remove the two knobs from the side of the cover. Then hit the case with your fist at the far end (plastic tab) and the cover should then pop off. You may have to hit it hard, with an upward motion.

Note there is not going to be much you can do to fix this beyond replacing the fuse. (Note that the fuse may be soldered in.) The bass amplifier is op-amp based with discrete class G output stage and the twiddler amps are monolithics with discrete class G circuitry shared between several channels.

The power transformer has a thermal fuse in it as well which is not replaceable. If you play the unit loudly for long periods of time and it is not adequately ventilated it is possible for the thermal fuse to open - if this is the case you will definitely need to send it in for service.

When plugged in there are hazardous voltages present on the top PC board where the power connector is located, whether or not the unit is turned on.

Power switching is via a triac controlled by whichever front end you have CD-5? 12V should be present on the mini plug (tip I think, but might be ring) when the music center is on.

There is also offset detection circuitry that will latch the unit off should any output have more than a volt or so of offset.

SOURCE: Harmony 900 to control Bose Lifestyle problem.

Press the system button on the Lifestyle remote control. Move right to see a preview of the remote control. Press the down button to move into the submenus. Go down to IR Control. Select "on" System receives IR commands from another remote that has been taught to operate this system. Press exit and take a breath and try your Harmony remote. It should work. I had the same problem and this fixed it after hours of screwing around. Good Luck

I also get this problem sometimes with mine. Usually when you call Bose they suggest that you do a "hard" reset meaning you unplug the power cord from the wall and wait about one min. Then plug the unit back in and it should work.
The other thing that you can try if the system still isn't working is to check that all the wires running into and out of the sub-woofer are all plugged in and aren't loose.


If either of these two solutions don't work you can alway call Bose tech support @ 1-877-210-3782 (they are open Monday Friday: 8:30 AM 8:00 PM ET)

What makes background sound comes out from Bose lifestyle 38 system is because there is jack cable or a cable that has a jack mouth that brings out a mono sound is being inserted..

Mono cables, when inserted inside a wrong input,it's makes the sound comes out with a background noise just like the one you can hear from it now..it seems as if you are not using the right cable for connection..

To resolve these issue, you will need to use the right cable for connection, by doing these,you will get a clearer sound from you Bose lifestyle 38..

Also it can be from the settings inside the Bose lifestyle 38...So you will need to check both sides to resolve this issue..

You will need to use the manual to know the right cable and the right setting for clear volume..

Is it possible to plug an Ipod into this system?


Hi, it is possible. All you need to do is get a two to one RCA cable. (one side RCA that has two mouths stereo, and the other side will have a jack mouth that will go into the ipod.

Connect the RCA cable to the output of the bose lifestyle system and connect the jack to the input of the ipod(where you plug your ear phone in.).

After that, set the bose to AUX. and you can start playing songs in no time.

Take care.

Need to hook up bose lifestyle 5 music center to comcast cable sony braveo tv and sony dvd. was hooked up until move do not find manual


I'm in a similar situation where I am hooking up a TiVo Premiere, Panasonic Blu-Ray player, and a LG 47LH90 TV to an old Bose Lifestyle 5 Music Center. After reviewing all of my connectivity options, I've come to settle on the fact that my TiVo will connect via the "Video" input on the Music Center (via red/white RCA). The Blu-Ray player will connect to the "AUX" input on the Music Center. And I'll just have to switch between Video and AUX modes for what I'm watching at the time.

Can I connect my pc to a lifestyle 28 system


If you want to connect your PC's audio output to the Bose Lifestyle system, simply get a cable with 3.5mm stereo male plug on one end, and dual RCA male plugs on the other end. The 3.5mm side will plug in to your PC's LINE OUT jack. The two RCA male connectors will plug in to the Bose AUX IN jacks. On the Bose console (or the remote control) select AUX as the audio source. Your PC's sound will play through the Bose Lifestyle system.

For persons having a large library of MP3 music files on their PC, this is a great way to listen to the music on your hard disk.

Initial Bose Speakr Hook-Up Acoust 10-Denon RCVR


Hope this may help but you will disappointed. as heard from some pro, your amp will blow up the bose cube if direct connected to them, they are powering down your output to fit their tiny speaker. My understanding was you have to hook up everything to the bose module. They don't like to play with others.
