IF YOU get home to watch your prime time show of choice tonight and your television shows only black and white fuzzy lines, fear not - there is nothing wrong with your set.
It merely needs a retune, with some free-to-air digital TV channels in Northern New South Wales changing frequencies.
The retune will affect viewers who receive their signal from the Mount Moombil, Mount Nardi or Mount Springbrook TV towers.
This includes some viewers from Coolangatta to parts of Port Macquarie, but more importantly, it covers Clarence Valley towns Grafton and Yamba
Coffs Harbour North will retune on July 22. Suburbs affected include Moonee Beach Emerald Beach, Sandy Beach and parts of Woolgoolga. Manning River is due to retune at a later date.
The best way for residents to find when they need to retune, and how to complete the process, is to go to the website.
There may be some disruption to all TV services for several hours today due to work at the transmission site. Viewers should wait until after 5.30am before retuning.
There may also be outages to all TV services over the next two days. Viewers will not need to retune again - the TV services will reappear once the work at the transmission site has been completed.
People living in apartments may be using a shared antenna system. If channels do not reappear after retuning, they should contact their property manager or body corporate.
Viewers can find information about how to retune and any scheduled retune outages on the website or by calling the Digital Ready Information Line.
Viewers who are having difficulty retuning their equipment should check their manufacturer's handbook or manual for instructions on how to retune, ask a friend or family member to help, visit the retune website or call the Digital Ready Information Line on 1800 20 10 13, 8am to 10pm, 7 days.
