"Farooque Ahmed Shah this would most commonly caused by a failed main board as well as (to a lesser extent) by a bad T-con board. Try all different video input sources (HSMI, Component,Coax etc. Only use a local input i.e. DVD, BR or Game Console since errors like this can also occur with a bad cable/sat box or ROKU/Fire stick etc. Let us know what you find out.
@Farooque Ahmed Shah sounds like your backlights are okay. Post some pictures of your boards with your QUESTION. This indeed sounds like a bad main board (failed video processor). Adding images to an existing question"
