Power on and burn the 2A insurance, check that all the components are not short-circuited, and there is no wrong paste. What's wrong?

If you connect the load to burn or not to burn, if it is connected to the load, will it be caused by your load being too large? If it is not connected, it should be a short-circuit in your place or change a larger fuse to see if there is any output. What is the output?
