power to keypad but will not respond

Hi all, i recently purchased a used carvewright machine and supposedly the memory card was the only thing bad on it. Well i got a new card...finally, and stuck it in. The machine came on, and says carvewright woodworking machine but will not do anything else, i had a support guy tell me to format new card and try again, i did to no prevail. Could the contoller board have gone out and made the memory card fail as well? Is it just the connector cable? lol frustrated and needing answers....thanks to anyone with any knowledge of this happening.

Ok after going thru the machine again, wires boards etc, i have found the C1 curcuit unattached on the X termination board, after touching the second time the whole thing came off the board. Well this is obviously a problem, but would it be causing the keypad to just display Carvewright Woodworking System?
