    Hi Folks,
    We're now on our fourth Freeview box (connected to our main TV).Two other TV's in other rooms both have Freeview boxes connected which never give any bother.
    When watching the main TV,there is an intermittent noise which interferes with the sound.The only way i can describe it is like the sound you hear when someone rap a knuckle on a microphone to test it - a sort of dull thud.

    Any idea what could be causing this,and if it could be responsible for knocking out a Freeview box over time?

    We had a lightning strike years ago,and some of the aerial components were replaced (the TV picture is 100% on all channels),and yesterday i changed the scart lead connecting the TV to the new Freeview box to see if that would make a difference.

    Any suggestions very welcome :thumbsup:

    When you state "the TV picture is 100% on all channels"...do you mean DTV...Freeview channels?
    If so, why do you need a Freeview box

    I've moved this into the Freeview section, as it may be more relevant.

    1)The TV in question does not have Freeview built in - hence the need for the Freeview box

    2)Just wondering what could be causing the noise.(Occasional thud sound through the TV speakers)

    3)Picture quality is not affected in any way,but the boxes seem to just die after a couple of months connected to this particular TV.

    4)Could point (2) be causing point (3) - some form of interference affecting the Freeview boxes over time causing them to fail?

    No, I think you've just had particularly unreliable Freeview boxes.

    How are the TV and box connected to the mains? Wall socket, adapter plug, trailing socket?

    How often is this "intermittent noise"? Once a minute; once a fortnight?
    Does it coincide with, for example, a central heating thermostat operating?
    Does it still occur when every other electrical item in the house is switched off at the wall sockets, including lights?
