A lot of times it is due to a poor connection between the processing boards and the panel.

If you are brave enough remove the rear panel and reseat the ribbon cable connections. Then confirm all wires are properly connected.

If not that, you probably have a defective board or lastly the screen panel itself.

ya if you press your finger really hard on the spot above the line it might disappear but of course might reappear if it goes away that easy, i have had pink lines disappear on their own or after pressing on the sides, def a bad connection.
