I have recently started having intermittent signal drop (from 96% to 0%) on Sat C (110) of my Hughes Tivo box. The drop is immediate but lasts less than a second then re-aquires signal. It is causing almost continuous pixalating on Satellite 2 tuner. At first I thought the problem may be with the new W68 that I installed with the new slimline dish, but I just switched the two feeds going into the receiver from the multiswitch. The problem has stayed w/ Sat 2 which leads me to believe the problem is internal within the receiver. Any thoughts are suggestions would be appreciated.
