LNb problem

Gizmo2000

I bought my system a while back, went for a second hand Force D1122s i think it is but a new 1.2m Dish pack. I only had the system running for a month and the LNB packed. Went back to the shop and they changed the LNB. A few months later and the LNB seems to have gone again. I rang the shop and they said it was unlikely to be a LNB problem but more likely to be the receiver switching the LNB off or out. They have said the receiver will need repairing, has anyone heard of this LNB problem?

Hi,

Difficult problem m8,
You can measure the voltage to the lnbf, and see if it stays between 13 and 18 volt.

The lnbf's have voltage regulators inside so a bit higher voltage should not lead to the dying of the lnbf.

If in the menu the voltage is switched on to the lnbf, and no strange voltages are measured it still can be the lnbf's and you had bad luck to have 2 dud's in a row.

Did the LNBF's really die, not working afterwards?

Cheers,

Cor.

As Cor says Gizmo, did the LNb really die, what tests did you carry out to see if it had any life remaining?

What type of LNB is it and is it the same as the previous one? The sat shop can easily test it for you, I'm sure they have a dish they can connect it to. Have you tried your receiver on another setup? a Sky dish would suffice to see if there is a receiver problem.

What happened with the first one i noticed the picture going a bit fuzzy the day before then wallop it just died. Took it back to the shop and they changed it over no questions asked. A couple of months later, exactly the same thing, the LNB appears completely dead. As a somewhat newbie i bought a second hand receiver and new dish pack. However when i had a company install the dish they were none too complementary about the shop where i bought the stuff from.


I am not a techie so wouldn't have a clue about testing voltage but the LNB appears completely dead like the last time. The receiver itself is OK as is the dish.

It may well be the LNB at fault, but the problem you describe could be attributable to a dish going out of alignment, water ingress to the cable or indeed a faulty receiver. Do you not know anyone else with a dish to test your receiver?

When you go into the LNB setup menu, what are the settings?
