Well that makes sense. I took it apart, but things were so buttoned up that I did not go very far before getting cold feet. Not much dust in the part that I exposed. I did find a wire routed incorrectly which caused a thin metal shield to be slightly bent and in the wrong position. I corrected that and got it all back together. No symptoms upon restarting, but I expect it takes a longer time without power to cause the problem to surface. I will just wait to see if this gets worse in a hurry. Maybe I will time how long it takes for steady light and keep a record. It is a nice monitor--no reason to get rid of it at present. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
