Hello to all , I am having a problem where my machine switches on ,screen comes to life but has a line that flickers , I press manual then power and you can hear the contactor clunk but you can go no further , if you press input programming the little marker just scrolls continuously from top to bottom , I cannot get onto manual screen to reset servo etc. when I open the rear cabinet door on the servo I can read bb flashing and base block , it also shows bb on the three servo drivers, I have tested the power output I read about on one of the posts I read ,( the little white posts )and I am not getting 5volts and all other readings are about .5 of a volt down. it has a max control I forgot to say, any advice would be very much appreciated. ps. this is my first post so fingers crossed I have got it right.
