TV blinking

Yesterday I swapped out an old cable box that was not working for a new box.  The new box now has the TV blinking off and on withing a few minutes of turning the TV on.  Resetting the box allows the blinking to stop for a few minutes but it comes right back.  I've hooked up multiple TV's and the problem persists.  Is it the new box?

Yes chances are pretty good since that’s the only thing that didn’t change
