The system is working great except for the CD player. There seems to be a switch at the base of the cover lid that should be activated when the lid is closed. Nothing happens, but I can hold the lid open and take a small screw driver and hold the little white switch in and the disc will turn a little. There seems to be a short or a bad connection somehow. How hard is it to replace this switch and how do you take to cabinet apart to do it? Jimmywilson@unidial.com
