Does anyone have an idea as to why I get a black screen for TBN Rossiya and Rodnoy TV? Rodnoy Tv is on the same tp as CNL and CNL comes in fine. In the info menu of the stb both channels have the same signal strength and quality as the other working channels. My equipment is a Captive works cw600-s premium and a 33" dish with a tokyosat ts-300a twin ku universal LNBF which I bought new as a bundle for $160 on ebay. Could an incorrect lnbf rotation cause this?
