Hi elf2036,
I solved all the welds in the transformers, the measurements in ohm are similar comparing the windings one by one, then with a microscopic camera I made a verification of the welds and inverter components. There are white specks on this board labeled as capacitors, but I do not know if I can test them on the circuit. I make to a good clean with a product to clean PCB, to remove all flux solder and dust, but.... no results. I appreciate your help,
Thank you Carlos
