Check your coaxial cable connection and inspect it wiggle it while the set is on if the problem clears replace the cable. Check to see if the male connector that sticks out the back of the set isint loose to the point where it moves when you touch it. If it does you need to have it looked at by a tech usually this problem can be solved with a little soldering but could get more complicated. Depending on the age of the set the fluid in the CRT's gets old and cloudy and light cant shine through it makeing your picture appear fuzzy. Your local tech should be able to change the oil in your set. Finally you could have some bad filter caps but I doubt it.
