My Carvey powered down during an operation the other day. I flipped the power off and on and it came back to life for a little while, then did the same. It now appears to be completely dead. Powering it on does nothing and there’s no communication over the USB port.
I checked the power supply and it was outputting 48.5V. I suspected it was dead anyway as the fan had got noisy recently, so I replaced it with another power supply and it’s made no difference.
Is my board dead? What do I do if it is?
