Telecard plate. They do not show channels in good weather. What to do?

Question

A television

Since the spring of this (2018) year, most channels have stopped showing. More precisely, out of 50+ they show 3-5 on the strength. The plate has been hanging on the house since 2013of the year. All nuts are well tightened, does not go. It was aimed at a tree, but for 4 years it also showed with a tree, but then it took it and stopped ... It doesn’t show more about it: sometimes a picture flickers and a broken sound, but often it disappears immediately and there is no signal. There is 1 channel, which almost always shows perfectly - it’s not a delicate jewelry to anyone ... (but it can also be stupid) I tried to search through all the satellites - it finds more than 1000 channels, but they are all repetitive and if they show, then again, this is not for anyone desired channels. The most basic channels are not shown (first, second, sts, etc.). I tried to search only on the satellite on which the jewelry channel is also nothing. There are no federal channels at all. In 2013, it was configured by the master and the settings did not change.
Jewelry channel on SIRIUS2_3 5E satellite What is most interesting is the first channel is also on the same satellite, but it writes no signal all the time. I have no idea what can be done...
