... I looked at a number of youtube videos. Seems according to the videos with a blank screen, audio working and doing the flashlight test and able to see the image on the screen. The problem pointed to the main board. I looked at shopjimmy.com but he was out of main boards. Saw a used on on eBay and took a chance. First off when I power my tv on the LED's flash and I can see the image on the screen with a flashlight. The used board I got has zero response. No LED flash, no on scree image with flashlight. So I put my board back in and I'm back to where I was. Before I spend more money on non-working boards, am I heading in the right direction wanting to replace the main board?
LG 50LN5700-UH - screen went blank but audio remained ...
