Often, repairing an induction cooktop means replacing the transistor or transistors. These are the ones that often fail. Therefore, if your induction cooktop doesn't turn on, follow the example in the video and check the transistor and diode bridge.
Of course, a failed transistor may be a consequence, not the cause, of the defect. You should also check the resistors, shim controller, short circuits on the board, etc. But as experience shows, in 95% of cases, replacing the transistors solves the problem.
