After more than four hours without a signal to many viewers, Lexington television station WLEX-TV (Channel 18) resolved the problem with its transmitter, according to a post on the station's Web site.
The WLEX transmitter went down at 2:05 p.m. Wednesday due to what was believed to be a power supply issue, disabling the NBC affiliate from sending a signal into many homes.
Sean Franklin, operations manager for WLEX, said earlier Wednesday that engineers were working to find a temporary fix for the problem and were expecting a replacement part for the transmitter sometime Thursday.
The transmitter problem meant that only Insight customers or those with Direct TV standard definition were able to receive a signal from WLEX. All other cable or satellite customers, and those who receive the signal over the air, did not receive a signal.
