I see only half of the screen, model DP2849
Pascual , it can be the Tcon board or the LCD panel. If there is a clearly distinct sharp edged linear line between the bad side and the good side, it is most likely the Tcon board. If that division line from the dark side slowly blends into the good side and there is no clear cut edge to it, it most likely is the screen. It might help if you post a few images for further trouble shooting. Hope this helps, good luck.
