this tv had a bad screen ( ghosting and flickering). This tv is well know for this problem. most of the time there are 3 major causes : bad T CON board, loose flat cables or a bad LCD screen) also a bad lvds connector can cause some problems so also check the connector real good as well the cable.
Due to data loss on my computer i lost all the pictures to make this guide.. if you have questions , feel free to contact me.
