Hi, Wondering if anyone else has same problem. The humax box seems to be the culprit as the signal is lost on the hd fury vertex 2 and the vertex goes into a cycle of no signal, in0 to tx0 and tx1 found and then it displays the humax on tv for about 15 seconds or so then cycles again. Changed cable, ports, and everything else id working well. the only way of maintaining signal is to switch off auto switching in vertex. Thanks
