Hello-

I have an 8 or 9 year old Magnavox television that has a very
conditional problem. During the daytime, the picture is great, but when
it is dark outside, not just dark inside, the picture gets interferance
in the top 1/3 of the screen, in the shape of a thick black line that is
shaped like an arrowhead, that jumps from the left side of the screen to
the right. Anyone have a theory?

Thanx, Todd

Just a guess: Maybe a ham radio operator in the neighborhood, or
somebody fires up an electrical device at dusk that is emitting
interference. Lots of stuff are on photoelectric switches and come on
automatically at dusk.
