I have a 55"lg led tv. A few weeks ago the tv had no picture but it had sound. I would turn on tv. And the lg symbol would flash then the screen would go black And yet would have sound. So I change the tcon board first and then changed the power supply board It worked for a few days after changing power supply board. Now it does the samething lg symbol flash screen goes blank and still has sound.
