All my magic eye's have stopped working, the lights on the boxes are still on. Also, the picture on all secondary tv's have suddenly developed horizontal banding which moves up the screen. I've checked the all the connections. I have a Triax 4 way bi-directional loft box which has been working fine for years. If I go into the loft and connect together the sky RFOut and one of the secondary tv's(i.e., bypass the loft box) the banding goes away and the magic eye works. Loft box knackered? It's never been touched lately at all.
