Hello,
I have a problem with the power supply of LG 42LM620S, the power board is EAX64427101. The problem is the pfc circuit, when I connect it the board has a short circuit, but If I remove L601 the board works fine without leds light. Also, if i disconnect the F101 the board is in short circuit but the pfc circuit works fine, 380V. i changed the fan7930, the mosfets q101, q102, q602 and q601. Also i changed IC101 ( L6599). To eliminate circuits I removed d254, d260, d253,d261, d251 and q251.
I have not idea what more check..
