Does not turn on, nor does the stand by LED light up | Main voltages were all present, after searching a lot, I arrived at q403, a MOSFET that is below the microprocessor, which was missing the 3.3v, I followed to see wsound this 3.3v was coming from, I reached fb702, which is connected to the u702 voltage regulator. 3.3v, I tested the fb702 and it was fine but in the test it didn't continue until the q403, then I realized that the fb702 was loose, it wasn't making contact with the board. | Solve fb702 | Strutz |
