B92A no sweep


I forgot to mention that, initially last week the problem began with the sweep working fine for the first 30 seconds and then quit. It might come back for a few moments, even another 30 seconds on occasion before not working at all: I assumed from a component warming up. This week however it has not worked at all. I was able to use a thermal camera to look at heat on the boards and found nothing unusual.Whatever it is, it isn't intermittent any longer.
