I don't live in the area. So, I can't tell you with 100% certainty, but KLSQ would appear to still be silent based on FCC filings.
Seems to me that there's no chance Univision's other stations in Las Vegas would go silent. KLSQ went silent due to a power issue at the transmitter site. KISF and KRGT don't appear to be at the same site and wouldn't seem to be affected. I don't know how they're doing revenue wise, but they don't seem to be getting the ratings they once got. I can't, however, imagine Univision just taking them dark. I'd think it would sell before doing that. Even just for stick value, both would fetch a relatively pretty penny (though the current climate would obviously hurt station values).
