on february 26, 2008, the klystron tube that powered wnit's transmitter failed, which reduced wnit's analog signal strength to only 15 percent of its normal 1.38 million-watt effective radiated power. the transmitter's major signal amplifiers subsequently failed on march 25, completely disabling the station's analog signal. with analog broadcasting due to end in the united states in 2009, the station opted to broadcast solely in digital. most viewers did not lose access to wnit programming due to the high penetration of cable and satellite television in the area.
