Red hue screen? Does whole display need to be changed or can be repair

@pauljonjosh verify first that this happens on all inputs and is not isolated to just a certain one. Then check to see if your onscreen menus are red tinted as well. It will help if you can post some images of what you see with your question. Use this guide Adicionar imagens a uma pergunta já existente for that. That way we can see what you see. It can be caused by things like a faulty main board, faulty T-con board and loose, corroded dirty, or faulty LVDS cable. Of course, a bad panel is also possible. Make sure that your settings are all proper and see if you can decrease/eliminate the red hue.
