That's not dead... that's the "error" indicator


Unplug chain 2 and 3 PCIE connections + control board connector.

Try to power up with just chain 1 to get it back online. Try to adjust the fan speed and frequency (increase it or decrease)

Try to unplug the PCIE pins and re-plug along with replugging in the control board connection.

Try to plug it into a different wall outlet in your area.


It's likely that the board isn't dead and it's just a power issue.
