First, test the control panel's tuning voltage. It should be within the normal range of 0 to 5V. If the voltage falls outside this range, it indicates a malfunction in the control panel. In such cases, the control panel needs to be replaced.
Step #2:
Measure the control panel's first-level drive voltage, which should ideally be around 2V. If it deviates from this value, it indicates a malfunction in the control panel. In such cases, the control panel needs to be replaced.
Step #3:
Measure the control panel's second-level drive voltage, which should ideally be between 1V and 2V. If the voltage falls outside this range, it indicates damage to the control board. In such cases, the control board needs to be replaced.
Step #4:
Measure the front drive power supply of the control panel. The normal voltage range should be between 0V and 12V. If the voltage deviates from this range, it indicates damage to the control panel, and it needs to be replaced.
Step #5:
Measure the power input voltage in the power input board, which is typically around 2V. If the voltage deviates from this normal value, it indicates damage to the power input board, and it needs to be replaced
