Has anyone here had any issue(if you've ever owned one) with the display on the kd-sh1000? I read a while back on DIYMA that this was one of the issues when this was a forum boner. Given that I've kept it long enough to see this for myself(as well as the usb starting to act up)has anyone else had experience with this? If so, is it as simple as cleaning the contacts for the face and the usb?
