Adrian if the TV turns on (channel audio is heard) then the fault is in the LEDs.

Adrian but you comment that the TV turns on! or it will be only that the stanby led (red) turns on, if so, the fault is the main board.

THE TV LIGHTS THE MOST WELL, THE LIGHT OF STAND BY PASSES FROM RED TO BLUE, THE SUBJECT IS THAT I DO NOT HAVE LIGHTING OR SOUND AND IMAGE ... THAT IS WHY I WANT TO BRIDGE THE SOURCE TO REMOVE THE DOUBTS OF THE LEDS ..... BUT I DON'T KNOW HOW TO DO IT IN THIS MODEL ...... I WANT SOMEONE TO TELL ME THE CONNECTIONS IF POSSIBLE .... TO GO DISCONTINUING ..... BEFORE BUYING A MAIN AND THAT IS NOT THE SUBJECT ... ..

Adrian that fault along with LW Lg models are due to overheating of the micro, the main must be changed.
