I been having a problem with my TV. I have never worked on TV and could
really use some help! My picture gets all fuzzy and jumpy. At first I
thought it was the cable or connections. I replaced the cables and made
sure
all connections are tight. The picture returns to normal if I jiggle the
connector on the back of the set or smack it on the side once or twice.
Could somebody please help me.

Probably cold solder joints on the tuner, or antenna input.
