Hello Davi.p,
forgot to attach some pictures of the One Connect Box and the One Connect Cable that I write about, sorry for that.
The TV has only one connection on the back and this is for the One Connect Cable. This model of the One Connect Box provides the TV with everything it needs over the One Connect Cable. Have attached some pictures of my model from a tear down clip that I found on youtube. It's from a 43 inch model but the Box is the same.
There are 3 Mosfets on the mainboard and about 5 on the BL PSU and non of them is shorted. But one on the mainboard, a P-Ch 30V 50A,...

Hello everyone,
