Replace the screen. If it worked fine for a year after you got it, nothing the seller has to do to fix it. If you just bought it, return it.

The seller said he used it only once and it was in the box for an year as he didnt like the 3d and bought another one so until now it was used only once and i am not saying anything about the seller, what is the problem and how do i fix it at home without replacement, thank you.

Need to get a new screen, although possibly there may be a connection loose or it's an issue with the system board.

how do i check for the mainboard issues and if i have to change mainboard or the screen whats your guess of how much it would cost, i might have to return it back if its too much to repair, but because rhe line is small compared to the big screen how did it happen any guesses, thank you.

To check if it's the board, need to replace it or have a tech look at it. You can look up the cost of the board online, and for labor you can check around your local tech shops. I'd say a few hundred for total. But if that is not the issue, you would need to replace the screen. A local tech should be able to tell you where the likely issue is though. "great price" is there for a reason LOL.
