A lot of channels have disappeared on the satellite, there is no signal, etc. What to do?

Question

A television

I’m asking a question a little there, but I think there will be people. So, there is Orton 4100. The picture disappeared on several channels, I scanned it, dragged it to the right place in the list, deleted the old ones, everything is OK. Turned off (as usual, the cord from the outlet). And when I turn it on: most of the channels are gone, and those that are - there is no signal, the order is somehow not the same, previously non-existing ABS, YAMAL and something else appeared. In general, he seemed to have gone crazy. But because of this method of shutdown, it should not, because. it turned off not at the time of saving, but when a certain channel was simply turned on. What happened to him and what to do?
