Bsc422 dms LNB Woes

Seek installer for LNB problem - White Bear

I hope this is the right forum and if not, perhaps a mod can move it.

I don't have a tester and so have been spending way too much time trying to align a BSC-422 LNBF from DMS on a 6' dish.
I had a single LNBF installed but didn't want to keep switching between receivers so I changed it to a dual. I tried putting the single back up but now I have the same problem of not being able to find the sweet spot.

Anyhow, if someone could contact me, I would appreciate it.

If you have a small TV and an extension cord, place your receiver near the dish and use the internal meter to optimize the Signal Quality.

If you are looking to contract a local technician to align your dish, visit www.FTAinstall.com

The signal isn't really the problem, I can easily get a big signal. It's getting both sides of the signal that's not working.
I'm not sure how to explain it but anyone who knows W5 would know what I mean.

 

[SATire]

BTW, I measured the voltage coming out of the receiver and found that it's always 11V or so which makes sense since I took the reading inline with it powering the LNBF.
Thing is, switching between 240 and 241 should have switched the voltage from 13Vto18V but it remained the same.

 

[Mr Tony]

are you not getting both polarities on one side?
I'm confused as to what you're asking

 

[SATire]

I don't know how else to ask it since I don't know the terminology.
The best explanation I can give is that when Skyvision has me test, they have me flip between channel 240 and 241.
They then asked me to check the voltage to the LNB which is what I posted.
What else can I provide that will better describe the problem and I'll do that.

This is a new thread for the previous problem... Probably should have continued on the original thread. Iceberg, maybe merge these threads?

I don't think that the problem is with finding the sweet spot.

So you have tested the 4DTV and it is not putting out the correct voltage to power an LNBF and switch polarities. This is the reason that this receiver is not switching between polarities on an LNBF. LNBFs usually require 11 - 15VDC for vertical and 16-20VDC for horizontal. Is the receiver configured for controlling a LNBF?

Now test the other receiver. Does it put out 13VDC on a vertical transponder and 18VDC on a horizontal transponder (+/- 10%)? See post 19....

You keep asking questions, but not replying to specific questions. We could probably assist with more information.

 

[Mr Tony]

I merged the threads together

I wonder if on the 410 there is a setting that isnt right? I've used both FTA receivers and DCII (mine was a 905) receivers on a dual output LNB just fine

 

[Mr Tony]

I checked Lyngsat and cant see what channel 240 & 241 are to verify they are on opposite polarities
What is the channel name?

I tested the voltage on the coax in-line to the LNB as I was switching channels. The receive is the DSR410 I'm sure you know. The voltage always remained the same, around 11V or so. It would drop some because it's powering the LNB while I'm taking a reading right. So, depending on what the LNB requires, would it be safe to say that it's only working on V since it's not putting out any higher voltage?

I only have the one DSR410, the other that is connected to the same dual LNB is a geosat. Do you want me to test that?
And so I understand, for what purpose?

>You keep asking questions, but not replying to specific questions.

I asked this question once and never completed it. I just have too many things going on at once is my problem.
When I came on tonight, I completely forgot about that one else I would have gone back.

take the FTA receiver and put it on the cable line that the 410 is on right now...in essence swapping them out. If the FTA receiver can show both 13v & 18v then its not the LNB output and might be an issue with the 410

 

[SATire]

What is the channel name?

FXM is 240
IFC is 241.

The test I ran for example, gives only 11V, and the channel which is working is 241. The 240 channel isn't coming in.
When I was out there rotating the LNB earlier, I could flip 240 on, 241 off, and vise versa. The closest I came to getting both was pixelation on both but that's as close as I came after over 2hrs of trying. Figured when we got even pixelation on both, that we would be close, so tried moving the LNB in and out as well and never got anywhere.

The way it was connected was that I had only one cable to LNB. That cable went into a motor controller, then that went into the geosat. The geosat has a loop which I used to connect to the DSR410.
That worked (with the missing channels) but then I thought maybe the problem was because I was looping through the geosat, thinking that the DSR410 wasn't able to power the LNB as it needed. I then used a dual coax cable so the LNB is now individually connected to each receiver.

Ok, so, check the voltage on the geosat as well then? Only problem is I won't know what to switch between in order to generate the two voltages.

Not sure if this is the issue but feel it necessary to say anyway. I use a Traxis 3500 and a 410 on the same wire via loopout on the Traxis. I found out that the 410 will cause havoc on the Traxis unless it is unplugged from power. Obviously the Traxis loopout is not the same as some receivers and let signal back IN too. Same goes in the other order too, have to make sure the Traxis is completely powered off or else it'll cause issues on channels on the 410 too.
Try taking your FTA box off the 2nd wire while using the 410 to try to narrow it down.
Sorry if I missed some of the finer details, I only skimmed over the thread and probably missed something before adding this info...it might not even be relevant.

>down.

Good call, in this setup, I had the lnb going into the geosat, and it's loopout to the DSR410. I thought about that earlier so put each receiver on it's own lnb connection to eliminate that potential.

 

[SATire]

Well, the fun continues. Skyvision suggested that I factory reset the receiver, which I did. Now the LNBF is totally dead so I need to order another one and of course, don't see a dual on eBay so will end up paying more than I should.

 

[SatelliteAV]

This makes no sense..... Resetting a receiver would not cause the LNBF to fail.

Does the GEOSATpro work with the LNBF? Did you connect the GEOSATpro to the coax cable and test the voltages as Iceberg and I have suggested?

 

[SATire]

I know it makes no sense, this whole setup has never made any sense. Always weird things happening.

I swear, I had signal on both outputs to the dsr410 and the geosat. On the dsr I was of course getting only one side, on the geosat, I was getting everything I had set up.
I then reset the dsr410 and now the lnb seems to be dead.
After than, nothing what so ever on the geosat or the dsr. At one point right after the reset, I did scan around by moving the dish and got a big signal on g17 but nothing else. Since then, nothing else comes in.

I checked the single that I pulled for resistance then checked the dual that is installed and the dual is wide open, no resistance what so ever.

All I can think is that the lnb has died.
I can't tell you how frustrating this thing has been, it's always something weird, seems I never have normal problems, always bizarre.

 

[Mr Tony]

well I had the pleasure of meeting up with SATire today to try and troubleshoot the issue and I am stumped too.

2 lines come from the LNB....one goes to the 410 and the other goes to the GBox to control the 6 foot dish. The receiver set up is the Geosat rack mount receiver. The 410 red light originally showed red regardless of sat. Moved the dish to various sats and the dish does move and did lock but couldnt find a signal. After some troubleshooting the Geosat needed a reboot (power switch off and on). Did blind scan and polarity was off so checked LNB...SATire set the LNB to 0 but as we know most of the LNB's seem to be 90 degrees off so moved skew so 0 shows like 3:00 on a clock. Checked Geosat and channels popped up. Swapped cables and both cables show both polarities. Moved dish to 105W

Did a master reset on the 410 and on channel 204 the green light for sat came on (this is normal..)...waited for channels to map but now I guess the same thing is happening. Can get one polarity but not the other

So this is where we need some help

 

[SatelliteAV]

Is the 410 still outputting only 11VDC?
