Yep I agree with all here,
Check your wiring for a short somewhere( maybe your RPK) , something shorting out against the back of your pcb.
You could also try restarting the system as described in the eng manual,
Suppose the last resort would be to default the thing, I don't recommend you try as the thing will need reprogramming.As said you be better getting a pro in.
Be safe and good luck.
