Sherri Celani this can be caused by bad backlight arrays. The phosphor coating on the backlight LED’s curls and it is this curling that cause a spectral shift toward blue. OF course make sure that you check this on every video input. Use all different connectors like component, Coax etc., to make sure that all of them show the same tint. If so it is most likely the backlight LED’s if not it could be the T-con/main board.
