Just came back from Christmas trip w/ family and discovered 2 problems. I have 3 High Def receivers (2 HR10-250, 1 Samung TIRS360). One of my two HR10-250's died on me (reset will attempt power up, then all lights go out) and most of my High Def channels are gone on the remaining 2 High Def receivers. Channel 80 & 82 (New York highdefs) are fine. No other highdefs are working (70, 71, 72, 73, etc.). All other standard channels are ok. After testing satellite signals strength, noticed that 119 had no connection on right and 110 had no connection at all. 119 was receiving 97% strength on transponder 27. Zero signal strength on transponder 26 or 28. No thunderstorms or any bad weather while we were gone. Hard to believe that all 3 receivers went bad while away for 5 days. Could it be bad LNB's or multiswitch?
