Mostly it was victim of consolidation. When it was part of a Clear Channel purchase, it was moved up the dial from 92.3 to 100.3 with lower power and Radio One ownership. Radio One was not able to "keep up" with Power, and it tried a hybrid talk format.
The Wikipedia article is fairly accurate and is at
KKLQ (FM) - Wikipedia (jump down the page to the section on the Urban format).
As a comment, my opinion (I was a PD in LA in that period at stations like KTNQ, and KLVE) Radio One did not "get" that an Urban station in LA had to principally appeal to Hispanics as the Black population was around 7%. Power always had a music mix that was intentionally researched against both Black and Hispanic rap / hip-hop partisans.
Because LA was rapidly approaching being 50% Hispanic in 18-34 and in the 40-percent range in 18-49, that Power focus on Hispanics put them over the top. In the pre-2000 era that Power had The Baca Boys, they solidified their hold on Hispanics, too.
