The station originally signed on as K42DT on analogchannel 42. It was owned by the Trinity Broadcasting Network. By 2002, the station was under the ownership of Venture Technologies Group, which continues to own it. From 2002, the station became silent, and was granted a temporary authority license the following year by the FCC. In May 2006 the station owners moved the station's location from Coalinga Ridge in Coalinga, California to a transmitter site on Mt. San Benito, and changed the station's city of license to Greenfield, California. KSCZ went silent at 4pm on Sunday, March 18, 2007, by Brian Holton of Venture Technology Group, licensee. Pending resolution of an FCC filing against it by Marty Jackson of Monterey, California, it was expected to return to the air serving Santa Cruz, California. On October 11, 2007, KSCZ-LP was granted an original construction permit for a digital companion channel by the FCC under the callsign of KSCZ-LD. The digital station broadcast digitally on channel 20 from a transmitter site in Fremont Peak, from where other Salinas and Monterey-area broadcasters transmit. KSCZ-LP went off the air on August 8, 2017, and resumed broadcasting on March 15, 2018. Several Vietnamese-language subchannels moved from KAXT-CD to KSCZ-LP. On June 1, the station changed its city of license to San Jose and San Francisco and began broadcasting from Mount Allison.
Programming
KSCZ-LD broadcasts mostly Vietnamese-language programming. Several of the digital subchannels are branded as San Jose stations and serve the Vietnamese American community in Santa Clara Valley. Quê Hương and VieTop originate locally in San Jose, while other subchannels are simulcasts of networks based in Los Angeles or Houston.

Former programming
It is unknown what programming the station previously broadcast, though it is assumed to have broadcast Trinity Broadcasting Network network programming under TBN ownership. It also broadcast a moving test pattern consisting of a repeating hour showing ships sailing under the Golden Gate Bridge, as viewed from the Marin Headlands. Video for this test pattern was shot by 2006 Venture employee Frank Martin. Music on the audio playing during this 'test pattern' was original compositions from Steve Salani of orchestra.net. This 'test pattern' repeating hour broadcast continuously from sign on at the Mt. San Benito site on May 18, 2006 until sign off by Brian Holton.
