For last two years I was not using my fta box. Which is a clone of PANSAT 2500a. Now when I try to access the satellites there is no signal at all. Am I missing something here?

Hey everyone, Hopefully all of you are having a good day. I recently learnt about FTA receivers and for $80 I bought a receiver )PANSAT 2500a CLONE FTA Satellite Receiver PANTEC 2500) Now I need some help setting it up. What else do I need to watch decent channels on my TV? If someone can...
