Weird. The fact the steering still works and the esc powers up makes me think there is another issue somewhere; usually the esc dies a silent death and nothing will happen when you try to power it back up, or the leds will flicker a little then it dies. Does the manual mention what the solid red led indicates? If the esc is recognized by castle link to let you reprogramme it, then it might be a radio issue (try recalibrating it or re-binding the rx to the tx if its a digital radio).
