Yesterday I opened up my tv to fix the fallen LED cap as white spots were appearing on the screen. After putting everything back and starting the tv a black patch appeared on the screen with no image . Guys what could be the problem ?

apoorva20.93  if we are talking about the area on the bottom right of the screen

that is a cracked panel. Not much you can do to repair. For now I would enjoy the rest of the TV but start looking for a replacement (search by the label number on the back of the panel) if available.
