I have a sky digibox, and over the last month it has developed intermittant noise interference?

Question

It starts off quiet and gets louder and louder( son says it sounds like machin gun fire ) . I have turned it off at the wall, checked all the connections and even removed the card in case there was dust on the chip. Nothing has been added to the system or removed. Any help or suggestions would be great.

Answer 1

call sky and see what they say there is a lot of things they can do from their end
