My bose lifestyle 20 system was skipping cds. i used the canned air to try to clean it out. i even took the alum cover..(thanks to someone here that posted the how to's ) now it wont play cd's. the connections are working. it acts like it is taking the first cd out to play, the 1 cd light flashes and nothing. it then moves to the 2nd cd and same thing happens. could the air have ruined the player??

Most likely you have a problem with your CD drive in the Lifestyle system. I suggest to contact Bose, to ask for a repair.

Have you tried completely powering down the system, removing the power cord from the wall socket? If not, please try that. Wait two minutes. Then plug it in and power up the system. If this does not clear the problem, contact Bose, to get the latest firmware disk. The firmware disk will reprogram your Lifestyle sound system. Then, everything should work properly.

I had the same problem with a Lifestyle 35 system. Use a DVD lens-cleaning disk, followed by the latest firmware disk from Bose. This should clear up the problem.

Might need a tune from bose repair man, Burnt dvds sometimes has problem but wipe normally fixes it. But cds i have't had problem burnt or orginal, scraches dont usally worry to much, Thats why thinking repair man.
Hope this helps:)
Cd normally hot from unit if its in for a while.

Hi Johnxxlt,
According to Bose, the message that you have is due to dust in the system ....
They have offered 3 ways :-
Try cleaning the CD or DVD, as follows: 

• Use a soft, dry, lint-free cloth to remove stains or fingerprints from the disc surface 
  
  
• Wipe in straight movements from the center of the disc to the outside
  
  
• Do not use any chemical cleaning products. They can damage the disc.

If the above will not fix the problem, you need to call them to repair the system.
I know its frustrating, However, we cannot play more with Bose as it might void the warranty if any.
Thanks for using Fixya.
Do rate the solution as "Fixya" if 100% satisfied.

Everytime I want to play an audio cd, it says format unsupported. This is happening very often. And I have also cleaned the cds,but still there is no difference. What is the solution?

There is a Manual Magazine release on the bottom back right corner. Pushing the lever back will release the Magazine.

Hi Capt Gene, Cleaning the laser lens is a good idea. Try to clean it with a 70% alcohol dipped Q-tip carefully. Or with specific repair kit, something like: http://www.shopping.com/xPO-Alera-Technologies-Aleratec-Disc-Repair-Plus-Cleaning-Refill Now about opening it, I could only tell my experience with my Lifestyle 20 system: I took the entire case off of my Lifestyle 20 system as the CD Changer Manual Release would not work. I removed all silver covers by carefully prying (glued on). Removed the there Phillips head screws in-line from left to right. Then I used a slot screw driver to pop the tabs under the end silver covers. Now I had an access to the motor and you can genteelly clean or grease Hops it help. Nuck. P.S All Bose could do was offer the $200 repair, which I refused
