Kinergetics KCD-40 Service?

I have a Kinergetics KCD-40 "Platinum" CD Player and I have been very happy with it for 4-5 years. Recently it started creating some scratchy/distortion after 5 minutes or so playing a CD. I have cleaned it several times and it is no better. Before you ask, I have isolated the problem to it by trial and error. Does anyone have any idea what this could be or any suggestions as to who could service it for me? Thanks for your help. -Durr
