My Zinwell 6x8 Multi-Switch just went Tango-Uniform. I get no channels whatsoever; that is, my three HD DVRS do the "searching for satellites" shuffle forever. I measured the DC output voltage of the switch at the grounding block during "searching for satellites." Two of the cables are stepping through voltages up to +18v, but the other two cables are nailed at about 1.5v (+/- 500mv). At no time did the stingers on any cable go negative with respect to the shield (I don't know whether they're supposed to...just reporting facts <g>). Now: I noticed that there are two unused outputs on the Zinwell switch, and they too are switching up to 18V.. My question: should I move the cables from the defective switch outputs to the unused ones? Thanks in advance. P.S. Ordinarily, I would have just tried this swap, but: the grounding block is in my toasty warm basement, while all my electronics are in my unheated garage where the current temperature is about 30F. I just don't want to FMAO if the proposed cable-switching is futile.
