1. For end users, we suggest applying RMA service from original purchased sales channel.
2. For skilled technicians or business partners, we suggest doing a standalone power supply test. First, separate power supply unit from the system and then check the no load output voltage. If output voltage is correct, then reinstall the power supply unit to the system and check again the status. If possible, measure the output voltage and current waveform for further analysis.
