I'm assuming the screen disconnect number is a rolling count .... I began having problems with one of my DIY's - and when I did what you described above ... the number was 133. then when I hit the fire button it jumped to 141 - but I only hit the button once, so maybe I'm wrong on it being a counter. Anyway, I'm replacing the screen in that one. A buddy of mine has a factory SDNA and a DIY and both of his read 2 - and do not change. Neither of them. One is having intermittent problems - the other has no problems at all. Any ideas on that ?
