    caveman,

    You need to be more specific with your location and where you are receiving the TV signals from, type of antenna, how it's mounted, any amplifiers and splitters, etc etc.

    The more info the better.

    firstly, check with your neighbours to see if they too are experiencing any reception problems.
    If its only you then you need to check your installation as mtv advises, if its everyone , thats a different story.
    The channels today send their signal out from one control location via microwave,cable,satelitte links and repeaters before you see it so one little hiccup anywhere in the chain and its gone.
    Some translators used to have a 'lost signal' message but mostly it just a blank screen
    I read that WIN had a control centre at Wollongong and Prime was in Canberra and from there they controlled over half of NSW but I have no idea where ABC/SBS Southern Cross 10 are controlled from.
    I would be surprised if Victoria was run any differently with just central control areas. If your close enough to South Australia, it could even be done from there.
    Also the weather could be causing problems, particulary in these current hot conditions by either causing atmospheric interference or overheating the transmitters if they are not well insulated.

    We sometimes experience "freak atmospheric conditions" here, (about 30 to 60 days a year )

    Where, we are receiving TV stations from over 300km or more away as strong as if you were in their local viewing area,

    The problem is that they are using the same frequency as our local stations & this causes interference,

    With analogue this interference shows up as Horizontal lines on top of the local transmission,

    (or a decomposed snowy picture for digital interference on a analogue picture)

    With digital it shows up as pixelation or picture drop out,

    this usually happens at night or early hours of the morning

    not saying this is your problem, just another thing to consider

    Eastern Victoria here, I had this problem and it was rectified with a masthead amplifier. Simple solution. Good Luck

    It's not always that simple.. amplifiers amplify noise/interference too.
