Vizio TV vertical green lines and on-screen menus keep freezing

Vizio TV vertical green lines and on-screen menus keep freezing I have a Vizio tv (model d39f-e1) where multicolored (mostly green) vertial lines appeared the other day. They are on the image in all input options, but not the menus. I did a soft reset and this fixed it for 3 days. ANSWERS:
