This station was first established in 1996 as K19BW on channel 19 with a Spanish general entertainment format, consisting of cartoons, classic programs, movies, and sports. Then on February 1999, the station was airing news from CBS TeleNoticias, thus making it a 24-hour TV station, compared to the daily 8AM-12AM programming schedule. By September 1999, K19BW was moved to channel 44 to make way for KTVT's Digital signal, then the station was rebranded K44FO. By November 2000, K44FO dropped the CBS Telenoticias affiliate upon the network's transition to Telemundo Internacional and became a flagship station of Luis de la Garza's TeleAmerica Spanish Network with a few original programs such as Foro 44. By March 15, 2001, the station was once again rebranded to KLEG-LP. Despite picking up the Mas Musica network temporarily, it has remained an affiliate of TeleAmerica.
In 2006, Una Vez Más Holdings, LLC has acquired this station as KODF-LP's repeater for Azteca América until KODF's analog shut-off on June 25, 2009, where KLEG continued to carry Azteca América programming. Una Vez Más has since acquired KLDT, becoming KAZD, with that station becoming an Azteca America affiliate. As a result, Azteca América programming was dropped from KLEG-LP on January 25, 2011. Una Vez Mas has returned this station to its original owner and it has gone dark for six months.
There were rumors that KLEG-LP would become the LATV affiliate for the Dallas-Fort Worth Metro (previously shown on KDAF Channel 33.2). However, as of 2011, KAZD has acquired that affiliation as well on channel 55.4. The station returned to the air in July 2011 multiplexed with Spanish language VMAS on 44.1, Indian comedy channel SAB on 44.2, an audio-only station playing south Asian music on 44.3 and a test pattern on 44.4. On August 10, 2011, the station's call sign was changed to KLEG-LD.
