Ok, my parents just got a new TV (Pioneer PDP 436SXE), and whenever it's connected to Sky, it trips the house's circuit breaker and turns off the power. After much experimenting, I discovered that it was the second Sky+ box upstairs, somehow feeding a current through the wires to the dish, that is in turn being fed to the downstairs Sky+ box, going into the TV and tripping the switch. Weird? The only thing I can think of is that somehow, when I've upgraded my Sky+ box (the upstairs one) with a bigger HD I've left some wire trailing, or something (I haven't had chance to check yet). But why, oh why has it only started to happen with this new TV? It's worked with 4 different TVs fine, but this new one just doesn't like it. Any thoughts?
