Hi,

After rechecking the board connections, I found that the pinout connector in the Output 2 slot was misplaced (shifted, as shown in the attached image) from its original position—likely due to an assembly error.

After replacing the connector, everything is now working correctly and the issue has been resolved.

Thank you for your support.
