VALERIE HARPER TRIBUTE 5 p.m. on MeTV. The Emmy Award-winning sitcom star Valerie Harper died last month at 80. She found her breakthrough role in the 1970s as Rhoda, Mary’s Bronx-born neighbor in “The Mary Tyler Moore Show.” That spawned the popular spinoff series “Rhoda,” which ran for five seasons. Harper went on to star in several television movies and make appearances in a variety of shows, including “Sex and the City” and “The Simpsons.” This three-hour tribute features select episodes from “Rhoda” and “The Mary Tyler Moore Show,” including one in which Rhoda enters a beauty contest but struggles with self-doubt.
