GPIO unexpected connection error causes USB to power

Today, when using GPIO accidental connection error, the USB can not supply power. When using DC power supply connection, the LED is bright but cannot be turned on. What should I do?

Hi, can you please describe more detail about “using GPIO accidental connection error”? Which GPIO and how you did to it?

A RaspberryPi HAT connection pin corresponds to an error that causes the 5V to be connected to the GND pin.

Looks like some component broken…you might need to run RMA process.

Cannot open now, connect the power, the indicator light is on, but it cannot be started, but the system in the SD card is normal.
