TV is a Samsung PN60F5500.
When I came home one night I could smell a burning smell coming from the TV. I turned the TV on and the screen was entirely black and pink (no picture). I took the back off of the TV and found a burn mark on the Y-Main board. So, I ordered a new Y-Main board and upper and lower buffer boards. After replacing them I now have a picture but there is all different color "grain" that is present. It gets better or worse depending on the image being displayed (at times you can hardly see it at all). Would this be caused by another part that needs to be replaced or is it more likely to be a bad panel?
