[QUOTE="spiney, post: 177360, member: 192438"] hang on, this is a bit trickier than I thought, but I think we're still ok ...... 1) The Fortecs have current limiting, and so if shorted you may have made the receiver "run a bit hot", but it should be still undamaged. 2) If there's no channel selected, because none are stored, then many sat receivers switch off the lnb output volts (because then there's no point!). For example, my Comag does that, although there's nothing in the manual to tell you that's what happens! Almost certainly, this is the reason there's no lnb volts. 3) In which case, to get lnb volts, you have to put "something" into the channels database, ie, values the receiver will accept as a "valid" channel. 4) I've looked at the Diamond user manual, at [URL="http://www.fortecstar.com"]www.fortecstar.com[/URL] . This says you can enter channels manually. So, either, a) just invent 2 "fictitious" channels, using random numbers, having vert and horiz polarity. As long as the receiver "accepts" these values, it doesn't matter that no such transponder and channels actually exists, as you're only trying to get lnb volts, not receive any real transponder! B) If the receiver won't accept random values, then try inputting actual real trasnponder values from anwhere on [URL="http://www.satcodx.com"]www.satcodx.com[/URL] (obviously, you don't have to be able to receive the channels, it's just to get lnb volts). You might also have to enter pids to make the receiver "store" channels. c) If neither of these works, ie you can't store any channels at all, then go into one of the blind scan modes. Again, it doesn't matter that there's no lnb connected, and no sat signal, all you're doing is making the reciever put volts on lnb output. one of the above - a,b,c - sould produce measurable dc volts. Don't panic, whatever's going on, it's unlikely that you've broken the receiver! [/QUOTE]
