I was having a problem with my very expensive 9 year old Sony 5 disc CD changer.  It wouldn't play the cd's.   It just kept skipping each one and then showed "no disc" in changer on the display.
I tried the solution above, and I can't believe it worked!!! I thought it would be stupid to try it on my Sony, but after the stereo turned off.  I turned it back on and it worked!!!
UNBELIEVABLE!!!! Thanks so much.
