Hi I have had my digibox for about two years now and for about a year my box has been crashing but mostly I have been losing more than half my channels. All the screen says is no signal is being received, but if I flick through some of the channels work( channel 4 and sky news always work). I have tried unplugging it and taking the card out, also I have tried the unplugging it and holding down the middle button to upload the new software and it still does not work. Is my box scrap and should I get it fixed or try and buy a secound hand box from somewere. cheers Dave.
