WIMMERA residents could experience interruptions to TV service on Wednesday.
Works to move to digital-only TV will affect western Victoria as channels change frequency.
The Wimmera was left in a state of panic when it first experienced issues in June.
Chisholm HiFi and TV Centre's Jeff Allan said works at Mt Arapiles were slated for the afternoon and possibly Thursday.
"There is no need for anyone to panic and attempt a retune if they lose their stations," he said.
"In most cases they will be there after the work finishes but some makes might be affected and require some retuning."
Wimmera television viewing was disrupted last month during similar works.
