I was plugging in my USB TV adapter with cable tv and it shorted out instantly. Visible sparks. It did not damage any components in fact the tv adapter still works, however it did blow a fuse after a long enough connection. Is there anything in particular that I should look for that would cause this problem?
Theres too much power going into the fuse. Try plugging it in to a different fuse to see if it blows that one also.
