What is the function of the resistor and diode above? What happens if the resistor burns out? How to solve it!
Personally, I think the resistor has a voltage dividing effect, and the diode prevents the current from flowing.
The diode is to prevent the equipment from being damaged by reverse connection of the power supply.
The resistor grill must be short-circuited.
The resistor plays the role of current limiting and voltage dividing, and the diode plays the role of voltage stabilization and preventing reverse voltage. If the resistor is damaged, the output DC should be interrupted in case of power interruption.
Measure the DC voltage between v- and v+, then measure the voltage between v- and x1/6, and compare the difference between the two voltages. I think the resistor can be short-circuited and it will not affect the DC power supply.
