Very common problem. You didn't give us many details, so I'm gonna guess this is the old channel 18 problem.
You also didn't say whether the neighbor tunes to this channel using the TV or a cable box or what.
Cable TV channel 18 is at 145.25 MHz. Loose connections in the cable system (probably on or in your neighbor's house) are the most likely cause. The technical name of this problem is "cable ingress".
Cable company near me used to have disney channel on 18, and ingress from ham signals caused lots of complaints. They changed the lineup to put something less widely viewed on 18 to fix the problem.
Call the cable TV company and ask for help with a cable ingress problem. Its their problem.
