  Bose Lifestyle Model 20, C-1 Repair Information

Bose has issued a safety recall on many Acoustimass Subwoofers manufactured before
April 1, 2006. Bose says they will fix it for free. We will not work on any Acoustimass subwoofer
that has not been repaired under this recall. Contact Bose at 888-260-0819 for further help.


   PLEASE READ: If your CD cartridge is stuck and won't eject its because something in the mechanism is
   broken. Forcing the cartridge out with a screwdriver will only do more damage. Typically the cartridge, your
   CD,s  and additional parts inside will be damaged.
   Include any extra magazines you may have when sending in your unit. The magazines need to be checked
   for possible defects that need to be addressed.

   Flat Rate repair for a complete overhaul / refurbishing is $499.95 parts and labor plus return shipping and handling.
   Flat Rate without CD mechanism service is $399.95 parts and labor plus return shipping and handling.

   Every Bose we receive is inspected and checked for current revisions and upgrades. Prices above include any revisions and upgrades.
   Equipment is fully aligned, checked and tested after repair to ensure original factory performance.

    Tips to keep your Model 20 in good operating condition.

  1. Clean both sides of your CD's before inserting in the 6 disc cartridge.

  2. Do dot use the "Random" play mode. This causes excessive wear on the CD mechanism.

  3. Do dot use "stick on" labels on your CD's. Labels get stuck inside causing jamming and broken parts.

  4. Remove CD's from cartridge before shipping (if possible). CD's will fall out of the cartridge while inside.

  5. Do not blow out dust with compressed air. Dust will stick to oil and grease causing instant problems.

  6. Do not let a service shop work on your unit if they are not fully experienced with past repairs of a Model 20.
      Proper repairs require special Bose test fixtures, alignment procedures and factory documentation including
      service bulletins and upgrades.

  7. Do not use any other power adaptor than the original Bose item (Model PS71). Incorrect adaptors will cause
      poor performance or may damage internal electronic components.

     Input - Output connections

   Separate AM and FM antennas are required for radio reception. 12 volt power is AC not DC.
   The correct Bose adaptor is model PS71. The PS51 adaptors are underrated and will overheat and fail.
   Speaker zones require special Bose cables that are connected to Bose Accoustimass modules.
   Serial data as well as left and right analog audio is sent to the Accoustimass module via the
   speaker zone cable.
   Surround sound processing occurs in the Acoustimass  module.
   Aux & Video 1 & Video 2  inputs are standard line level audio inputs.


Known Model 20 issues.

RF/EMI interference with CD changer operation.

The CD changer may not operate properly when placed on top of or near other electronic equipment. There is no internal shielding to prevent interference.
Solution: place a grounded shield between the Model 20 and other equipment or move Model 20 to a different location.

Blank display.

This is a common complaint and requires replacement of internal electronic components with upgraded
parts by a qualified service technician.

Lifestyle Model 20 Music Center is dead

My Lifestyle system appears to be dead with no display and no sound, which unit is bad?  Often times the display on the Music Center will go blank even though the system is powering up. If this is the case then audio would still come through the speakers when a radio station is tuned in or if a CD is playing and the Acoustimass is ok. 

Perform the following to determine the condition of your Music Center with a blank display.

  1. Verify the Music Center is getting power by pushing the CD cartridge eject button . You should hear the CD mechanism try to eject the magazine even if the magazine is not installed. If this test fails then the AC adaptor may be defective or not plugged into a good outlet or your cat chewed the cord, bad kitty!
  2. The power adaptor can be tested with an AC voltmeter. It should read 14 to 15 volts AC. Be sure to set the voltmeter to the AC range, not DC. The power adaptors are very reliable and seldom go bad. DC output adaptors will not work! Use only the original Bose AC adapter model PS-71.
  3. Connect a set of headphones or ear bud's to the headphone jack on the right side of the Music Center.  Using the remote control select CD (if the CD is functional and a CD is loaded) or FM (with FM antenna connected) or Aux (if an Aux input is connected). At this point one of the music sources should provide audio to the headset. If you do not have a functioning remote control press the "Source Select" button on front of the Music Center to toggle through the inputs until you hear sound.
  4. If audio is heard with any of these tests then the Music Center is powering up ok. If there is no sound coming from any speakers then the Acoustimass is probably also bad.
  5. As an additional  test, you can load an empty CD cartridge into the Music Center. You will here the CD mechanism try to load each of the 6 slots then stop.

 CD cartridge randomly gets stuck while ejecting.

There are many reasons why this occurs.  If your unit has not been serviced correctly in the past 5 years or more then the time is now. A full overhaul will address several problem areas. Several electronic and mechanical components need to be upgraded for increased reliability. Cleaning, lubrication and alignment are needed for proper operation.


    We have a limited quantity of Lifestyle 20, 6 disc magazines, used in good condition, call to order. $29.95 ea


    Don't use the rigid Styrofoam to ship your unit.
    This material is to rigid and does not provide adequate cushioning to protect internal mechanism.
