New Problem

[MDB in SE La]

OK......I'm not in the DBS business but I've help neighbors install, actually I did most of the technical work because I'd done it before, their Dish and DirecTV systems but I've run upon something I'm not sure about. How do you know that the LNB is alright. I'm talking about a Dish 300, I've tried zeroing in on 119 and 61.5 but to no avail. I'm of the opinion that the LNB might not be working. It's a dual LNB and I've tried the other side on the LNB and still no go.

I've done all the normal things sighting in the satellite, plumbing the installation, taking into consideration I've done this many times since I first started with Dish in late 1997, sometimes I feel I just 'dummied up' for some reason. Any ideas on the LNB possibly???????? Mike

There are ways to test an LNB, but they seemed too laborious to me. I just switched out the LNB with a new one and if it works...well, it works. If it doesn't...then you've probably bought one of their cheap switches. Proud burner-outer- of 2 $100 switches in mere days.

If you put another lnbf on the dish and it works and the system would not work with the old lnbf then chances are the lnbf was bad.

If you are not using a meter to peak the dish---how do you know that
a) the reciever is passing current down the RG6
b) there isn't a short or open in the RG6

you can short the RG6 with your tongue, but if something is wrong with the reciever, you might get zapped (I have--and the current on that cable would not power my meter up--I thought it was dead. LOL! I had to take a motrin or two after that!). You'll also get zapped if there is an amp in line--I know this also from personal experience. I highly recommend you use some type of meter.

Good thing you weren't holding it between your legs, you might have thought it was dead also.
You'd have had to take a Viagra or two instead.

what i do to see if there is current coming from the receiver is to short across the stinger and the screw on part of the connector real quick and look for a spark, no spark, no current.

Your cable could be blackened on the end. That's a good sign. I had some trouble with switches a while back and eventually gave up. I was getting shocked and burning out ports. The cable was making sparks on the floor! I admit, my method is.... not scientific and possibly costly. But if a second LNB burns out, you know it's not the LNB! lol
