If what your saying is that there are vertical stripes down the screen, You have a screen drive problem my friend. This could mean you will need to change the entire main board, the screen driver board if it is separate on this set, or the main LCD panel itself. These boards do not have any parts available for them and must be replace as a whole unit. Good Luck
