@Audiodoc, thought that is what I would like to do, I do not think that any dealer will allow me to open the pack and test the TV without paying money.
Since they will be unable to sell an open piece to an informed user in future.
So, I can perhaps just check the packing if it is sealed or not.
Secondly the current situation is that there are no pieces (display or new) anywhere in the state.
Hence, no chance of getting a display piece.
However, issues like banding/ dead pixels/ etc. will be possible only after I get the unit at home.
Let 's see.
