Is a LNB either good or bad? I'm losing signal strength,From 93 to 98 on an old RCA receiver.Somrtimes I will lose it all together for a millisecond or so. Or is it probably a bad connection somewhere? Tia

Need more information. In a nutshell, yes, LNB's can go bad. In fact, I had a triple LNB die on me, and I have a buddie who's dual lnb died on him.

But there's lots of variables. If u lose it all together for a second after seeing a 93 signal strength, I'd first check all connections and check that ur dish is secure and not blowing in the wind.

Yes LNB's do go bd from time to time. Check your dish mount/connections like hitdog said. Also, now that it is spring, is it possible new leaves on the trees has something to do with it? Just a thought. Good luck and go WhiteSox.:yippee:

Thanks for the advice. So the next question would be is it possible for the LNB to be intermittantly bad? I will check and redo the connections from the LNB to the switch.Hopefully that will fix the problem,if not then I guess it will be to start replacing componrnts. Thanks:)

do u have more than one box? If so, is it happening on all boxes?

If it , then ur looking at a lnb or multiswitch issue.

If u have just one tv and the sat is wired straight to that, start by replacing the ends of both cables. Always start with the cheapest repair first.

if u have more than one box but it's only happening on one, switch out the boxes and see if the same issue happens. I.E, if u move the box that's doing this to another tv and it still does it on that tv, it could be your box, especially if it stops happening with the other box.

Now, if the same problem happens on another box, same TV (following this?), it's either a bad cable or your LNB. Bad cable is rare, so I'd replace the LNB first.

So, in order:

Replace the ends of the cables, re attach. Check.

If still happens: Swap out boxes if u can. See if the problem follows the box.

If the problem happens on a different box, same TV, replace ur LNB.

If the problem persists on the same box, different TV, it is most likely a short in the box.
