EAY63168602 		TV turns on looks like the logo with a weak image or full of red dots then goes into protection Defect is a double diode showing low anode resistance for catode 150 to 190 homos, the correct one is that it presents a resistance of 390 homos upwards as an fcf10a40 was used instead and resolved the defect or use an equivalent in the place, this diode is in the el40 position on the board. power supply wsound it feeds tension from you.

LG 55LA6610
Doesn't start. main fuse open. Short at the output of the rectifier bridge, causing the fuse to blow. Shorted diode d603 (byv29fx) next to the primary power supply capacitor, and check the two smd fets that are underneath it. one of them (13nm60n) was shorted. I also recommend measuring the primary power supply capacitors as I found one altered. replace everything and carry out preventive repairs. PIXEL ASSIST
