Techs; This set has a hard blow on the line fuse. Lightening got several items in the home.I have checked the basic supply for shorts, open, etc. Pin 4 of STR57041 appears to be shorted to gnd. A pinout of this regulator IC would be helpful. Really could use a copy of the schematic if someone could upload to the document area of this website.
