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.
- 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!
-
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.
-
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.
- 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.
- 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.
