The original construction permit for Channel 45 was granted to the Central Florida Educational Television, Inc. in 1987. It was assigned the call lettersWLCB-TV, which stood for Leesburg Community Broadcasting, after the station's city of license. However, Central Florida Educational Television was never able to get the station on the air, so it sold the construction permit and partially completed transmitting facility to Good Life Broadcasting in May 2000, after the FCC began to permit duopolies. Once Good Life secured the permit, it completed the construction of its transmitting facility, and the station signed on for the first time on December 12, 2000. WLCB took a mix of general entertainment and religious programming. They ran a mix of westerns, old sitcoms, public domainmovies, some lifestyle shows, and initially cartoons, which by 2003 were gone. Their original station, then called WTGL continued on with an all Christian/religious format. Good Life owned and operated both its original station and WLCB until September 2006, when the original WTGL was sold to TBN and its call sign was subsequently changed to WHLV-TV. Good Life continues to host WHLV's master control operations to the present day even though WHLV has since moved to its own studio facility. The two stations shared a studio on the corner of I-4 and Michigan Avenue in Orlando until June 2007, when Channel 45 and the master controls for Channel 52 were moved to the former studios of WKCF in Lake Mary. With the WTGL callsign made available since the original WTGL became WHLV-TV, WLCB officially changed its call sign to WTGL on September 12, 2007. Even though the -TV suffix is missing from Channel 45's legal call sign, the station continues to use the -TV suffix on-air and on its Web site.

Analog-to-digital conversion
WTGL shut down its analog signal, over UHF channel 45, on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcasts on its pre-transition UHF channel 46. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 45. On March 9, 2018, WTGL began simulcasting via WUCF-TV; the station ceased broadcasting on RF channel 46 on March 28, 2018.
