Type of decoder? Location?

A lot of dishes in recent days and weeks have been knocked out of alignment after strong gusts of wind. A dish and LNB can be called an antenna. A good idea, when you get your reception back, is to mark the arm the edge of the dish and the LNB arm with a felt-tip pen or marker, so if it loosens again, you can reset it quick enough.

When you put the Dish & LNB up, did you cover the cable connection to the LNB in any way?

if nothing has been changed or moved in the bad weather, that error message suggests to me that you might have water in the downlead, and it's partially shorting out the Co-ax cable, and the receiver is detecting that and objecting to it. The other possibility is that the outer core of the coax has been damaged where it passes over a gutter or a sharp edge on the dish or similar, and water's got in there.

Another possibility is that the winds have moved or damaged the cable somehow, and there is now a mechanical short circuit between the inner and outer cores, which will upset the receiver, as it has to provide power to the LNB for it to operate correctly, unlike a "normal" TV aerial, which is completely passive.

One option would be to disconnect both ends of the coax, at the receiver and the LNB, and check the cable out with an ohmmeter, there should be no path between the screen and the inner core, if it's not an open circuit between the 2, then there's a problem with the cable that will have to be sorted.
