The nearest circuit to the fuse was the start circuit that consisted of a pair of NPN and PNP digital transistor 4k7 +4k7 resistor built into the transistor . By the way the part number for Samsung 153V start circuit transistors were the A6J PNP digital transistor and the A8J NPN digital transistor as shown in the picture. Sometimes only these transistors have problems shorted that caused the fuse to blow but in the above case both digital transistors are tested okay. From the result what you get are N channel FET located at pin 1 source , pin 2 gate , pin 7 & 8 drain and both pins joint together internally . As for P channel FET, pin 3 source , pin 4 gate and pin 5 & 6 drain and both pins joint internally .
