WDBJ-TV's (Channel 7) over-the-air transmitter failed early Monday, causing the station to go dark for about 20 percent of its viewers.
A tank that is part of the transmitter's cooling system sprang a leak, causing the tower to automatically shut down. Station staff worked on the transmitter throughout the day and received a replacement tank later in the afternoon.
The station had a reduced over-the-air signal restored shortly after 9:30 p.m., said Mark Barker, WDBJ's master control supervisor. He said the reduced signal should provide enough power to feed most of the viewers who lost service, but that technicians hope to have the full signal restored by today.
Channel 7's viewers who receive only the over-the-air digital signal via an antenna, or who subscribe to a cable service that relays the station's over-the-air signal, could not receive the station while the transmitter was down. Viewers who have cable and satellite systems that include Cox, Comcast, Dish, DirecTV or other services that use fiber-optic connections to receive WDBJ's programming were not affected by the outage.
