In my case when their engineers came to check Tatasky signals they said that they have to change LNB which may cost some amount. Then they left without doing anything because I need to raise complaint again to chage the dish. But next day when i faced same issue with signals then i decided to repair it myself. I asked my friend to see the signals test screen on my tv and i went up and started rotating the LNB slightly and as soon as my friend told me that signals are good then i left it there and since then I have no issues with the signals. You can also see some digree digit marks on the LNB. Check LNB picture for reference. I hope this help.
