Hello my friends, I need your help again. I am trying to repair a samsung np300e5a, which turns on but no picture appears and the fan runs at full speed, sometimes it turns on and everything is ok. in 10 times 1/2 works.
I just got a one schematic here in the forum and I'm not sure is correct for this model, and I do not have the boardview of this board, which makes it difficult to identify any component.
I notice also that the 1912a mosfet with 1.060v heats up a lot, And the coil next to it also heats, it replaces it with new and stays the same.
3.3v ok
5v ok
19v ok
MODEL: SCALA3-15 / PETRONAS-15 REV 1.5

thank you
