I have a when sony KP-53HS10. The picture quality is duplicated by a blue shadow to the right of objects on the screen. When the unit is powered up it blinks 5 times. After diagnostics were performed it displayed 5AKB - 42.  Larry can you explain this code to me, and can it be adjusted or fixed in home by me. I just finished reading all the posts in this forum and could not find a post that referred to this problem.
