VESC won't turn on - RED LED

VESC 6MKIV suddenly will no longer turn on. When the power switch is pressed it lights up blue as expected but only the red LED flashes once. The blue LED never turns on. Any ideas on how to trouble shoot?

Probably a dead 3.3V regulator or short in the STM processor. 5V is vital, since you get a blue light on the switch. So the DRV seams to be healthy.
