Hi, this is really strange..... I have a H2h in the living room. It is connected to satellite and cable. In my dining room I have a openbox connected to satellite (separate lnb from living room one) If I'm watching the openbox in dining room and someone either removes sat cable from h2h or even the hdmi cable the openbox goes off (no signal). Not got a clue what the problem is! Also it makes no difference whether the H2h is powered up or not. Please can someone help??
