Those channels all are related in the same tuning band that most tuners have----suspect you have a bad tuner--unless you are using a box in which case suspect the box is the issue.

If the tuner is the problem there are ways around that--used a cable box set to the rear inputs (audio/video) on your set and bypass the problem.
