Tylan Hart 75” is a beast to work on ;-). Since it worked before you moved it, let us assume that this is not (yet) a board or panel failure. I suggest that you remove the back cover and double check (by removing and re-seat) all the LVDS cables. I would specifically focus on the LVDS cables from the main board on to the panel. It is possible that one/some have come slightly loose etc. As was mention earlier in a comment, pictures always help since for now we can only go by your description. Also, what exact model is your TV.

Can you take a picture of the TV screen while it's on and post it here? Adding images to an existing question
