[2] Trinity was left alone in its bid for the channel after Warner Bros. withdrew applications for UHF television stations in Chicago, Fort Worth and Houston, afraid that its antitrust record would result in lengthy and costly comparative hearings.

KFWT-TV began broadcasting September 14, 1967,[6] making it the first of three new UHF television stations in six months in the Metroplex (alongside two Dallas-based outlets, KMEC-TV and KDTV).

[7] By August 1969, however, financial difficulties had forced the station to go silent; at that time, Trinity owner W. C. Windsor, Jr., was reported to be in talks with a group of investors on the West Coast, including entertainer Danny Thomas, to buy KFWT-TV.

[8] The station spent a week off the air, temporarily returned after the FCC failed to grant permission to cease broadcasting in a timely manner,[9] and then went silent on September 3.

[11] That October, a debt payment plan was agreed under which KFWT-FM was sold for $315,000; by that time, Trinity had $1.8 million in liabilities compared to $670,000 in assets.
