My Dbox has started chirping pretty badly as of late. I'm getting chirping across the board including the FTA channels. Some channels are unaffected, but it's mainly FTA, E4, Bravo, SS2, UKTV, that have pretty bad chirping. I'm running Andromeda 2.0, taken out all of my splitters and running direct from feed, could my box be getting faulty? Is there anyway to check?
