It happened one day out of nowhere and there is no picture with it and can’t access any menus. It is just black and really dark grey bars running horizontal.

@darrinthehunn horizontal bars usually originate from failed gate drivers. Those are part of your panel and thus very unlikely to be repairable. Post some good images of what your screen shows. Use this guide Adding images to an existing question for that. That way we can see what you see. You also want to let us know if you have audio.
