I'm repairing an LED screen gaming notebook. The screen has a short circuit, and when the notebook is plugged in, it won't turn on. I found the short by removing the coil in the red circle, and by injecting voltage, I see that the Richtek power supply in the blue circle is heating up. Therefore, I have located the fault.
