Hello and I'm sorry you're having problems. Offhand, you really should have vocalized this issue to Bose at the onset of the problem, the reason being is that there are no pushbutton fixes for this, and they only repair units that are under 10 years of age. A 15 year old unit with a problem from the get-go is not repairable due to lack of parts available. I am sorry for being the bearer of bad news, but there is literally only ONE solution to this problem and that is to contact Bose directly and request that you may trade this unit in towards purchase of a new/current model at a discounted price. This is something they have commonly done in the past. I'm sorry for the bad news and wish there were a quick fix for this.
