Thought I would post this in the thread in case others have the same issue.
My old 40" LG LCD TV dropped many ago from the fake wall it was hung on. The LCD looks good, no cracks etc. The TV was on at the time and the power board tapped the metal piece it was raised off. So the TV does not power on (no little LED light either so defo aint getting power). You can see the little black mark that was made when it tapped the metal piece.
If you can repair this TV then dude you are tops and invited to all my braai's
