KCET continues to weather challenges following its departure from the PBS system on Jan. 1. The latest is a cable glitch, according to the Los Angeles Times. Time Warner was supposed to convert KCET to an all-digital signal last week, according to station programming chief Mare Mazur. The switch “should not have affected any subscribers with digital boxes, which according to Time Warner represents about 90 percent of their customers,” Mazur said. But KCET received complaints from viewers. The outlet has since been working with Time Warner to try to resolve the situation. The LA Times could not reach a representative for Time Warner Cable for comment.
