Rotating LNB gives signal to frequency 12152 and 11842 but loses it for 12115

[Stargazer]

I have tried adjusting signal on a Glorystar satellite today and can get signal on one transponder when the lnb is rotated at one location but get it in on the other two when rotated to another location. The signal strength is strong on them all but cannot get them all at one lnb setting. Note: no dish adjustments were made while rotating the lnb and quality is between 50 and 65 on those three transponders.

Any suggestions as to what is going on as to why I cannot get all the channels at the same lnb polarity position? The one position is at -19 as it should be but the other one is rotated way around from there off the scale. A simple rotation to one position gets the one set of channels in and the rotation to the other position gets the other set of channels in.

I used a First Strike meter to tune it in and the whole system came from Glorystar.

Is the receiver activated in GloryStar or Advanced mode? If in Glorystar mode and the meter is not in line, check that the receiver is outputting 18vdc on horizontal transponders and 13 vdc on vertical transponders.

If in the Advanced mode, was the meter in line when you scanned for channels? Is the meter in line when you are checking for reception on the two polarities? The meter in line will lock the polarity output of the LNBF and the receiver would be unable to control and only one polarity would be outputted from the LNBF. Manually rotating the LNBF overrides the voltage switching error.

Were any menu setting changed on the receiver? If so, which settings?

If all else fails, perform a Master Reset and reactivate the receiver. Make sure the meter is NOT in line when checking polarities with the receiver.

As far as I know the receiver is in Glorystar mode. It downloaded the channels.

I checked the signal with both the meter in line and not in line and got the same result on the meter and get the same result on the receiver when it is directly connected to the lnb and when it is connected through the meter.

Maybe the LNBF is not switching polarities or a bad cable or connector. Try a spare LNBF to verify operation?

Multiple receivers connected to a single output LNBF using a splitter?

[Stargazer]

There are no splitters, it is a single output lnb. It is a new system that the lady just ordered from Glorystar. It wouldn't be a bad cable or connector since I tried it from the lnb to the meter itself so the meter is reading the same thing the receiver is reading when I do hook back up to the receiver.

Do the lnb's go bad often?

[Glorystar1]

GEOSATpro LNBFs are rarely defective due to the double testing performed at time of manufacturer.

Did you swap out to another LNBF to trouble shoot?

I would recommend that installers and technicians always carrying a spare LNBF for testing, trouble shooting and another for sales. Carrying an inexpensive and common replacement item will assist in trouble shooting and cut down on return trips.

[Stargazer]

I have not tried the spare lnb that I had with me, forgot about that. I never thought it would be a bad lnb since it picked up signal from all of them in a different position but did not think that there could have been a polarity issue. I could try putting that lnb on the setup at my house to see if I have similar results here.

You did check for a warped dish???

[Stargazer]

Yes I did, with the strings, there was a very small space between the two strings and that was a metal dish. However, I just ran a test at my house using a used Glorystar LNB with a Coolsat receiver and am getting similar results here and I am using a 36" wide 39" tall fiberglass dish (not prone to warpage like the metal ones are). When you turn the lnb 90 degrees it gets the other set of channels in.
