TELEVISION screens are expected to go blank in the coming weeks as channels change frequencies as part of a national program.
The Tower Hill transmitter will be retuned on August 26, part of the national program to free up broadcasting spectrum for new services such as mobile broadband.
It follows on from the retune of the Warrnambool City transmitter in Albert Park in May.
The Department of Communications said there may be temporary disruptions to all TV services from the Tower Hill transmitter between August 13 and 15 from 9am and 3.30pm.
The department says service outages on the days before and after the retune on August 26 may also be necessary because of work at the transmission site.
Viewers will need to retune their TV, set-top box or digital TV recorder to find the channels that have moved following the retune.
“There may be some unavoidable temporary outages to some TV channels from September 17 to 19, these outages will take place between midnight and 6am to ensure any disruptions are minimal,” the department said in a statement.
