I've got a BK Precision 810C Capacitor tester/meter, that says with a big Yellow "!" on the front to discharge the capacitor before connecting, and not thinking, didn't do JUST that. The screen instantly went blank, and now it's dead. This is what I get for trying to help a friend! Fuse inside is good, replaced the battery for good measure, and it's sat for days and still DOA. Anyone ever fixed one of these or sent it back for repair? Or is it time for a new one? If so, any recommendations? This is a BK Precision 810C and one thing I don't like about it is the limit of 2000uf.
