B-G431B-ESC1 shows Iq even without connecting to power / motor

i started working on the B-G431B-ESC1 board with a 2836 motor but it would not start. so i started looking at the setup and tried different configurations but no luck. the profiler would not run the motor either. 

after i disconnect the motor and removed the bus voltage, the Iq in the motor pilot still shows significant numbers.. i wonder if this is a sign of damaged board?
