SAMSUNG	UN50TU8000G	Turns on, lights up LED bus and turns off, no image, stays in this loop	I saw several videos trying to isolate the cause with the famous tape on the flat, that procedure of searching until you find a point that releases the display short and the TV releases the image.	I couldn't do it that way, because the short was in the first left flat, that is, looking at the TV lying on the counter with the screen down, the flat that was preventing the TV from working was the first one on the left side. on the left side vcon board tsound is the test point "vgh", the track of this vgh that goes to this flat was cut and the TV worked perfectly without any scratches on the image, to make the cut easier the cut was made close to the r44 on the left side vcon board, please note Tsound you have the vgh point test and the cut I made right after, that is, I will remove this vgh reference that goes to the first left flat...
