Centroid Community CNC Support Forum

New to forum. First post.

I have a Millport Super Red Rhino 5 axis with the cnc10 ver? M400 control. Ser # 10853

I had the power supply go bad. Replaced it. Ran fine. Then a week later, turned on machine and the screen began scrolling the startup commands but froze in the middle. I shut power off. Turned back on and now the control will not power on.
I have tried
New battery
New power supply again
Bought another motherboard from internet (used)
Different ribbon cable from motherboard to hard drive (? circuit board with sd card)
Different hard drive (?again not sure if that is correct term)
Different sd card
Plugged different monitor into serial port

When I jump the power terminals on motherboard the lights flash on face of control for x y z jog etc, but nothing happens.

Any help diagnosing is greatly appreciated.

Thanks Scott

I got it. Replaced CPU and it works.
