Hello my friends I have mindray dc6 When I press the side power button, the device flashes and I hear the relay sound and it disconnects. The voltage on the PFC board capacitors reaches 390 volts and then suddenly drop and the device can't complete

The issue could be due to a fault in the PFC board, specifically in the control or protection circuits. The PFC board charges the capacitors to 390V, indicating the BOOST APFC power circuit is working initially. However, if the voltage drops immediately, it suggests the system is not sustaining power—possibly due to a malfunction in the relay control, soft switch circuit, or a short in the downstream +5V or -5V boards. This can cause the system to flash and disconnect after pressing the power button. Replacing the PFC board may resolve the issue.
