Previously had uncorrected problems with boot up due to A11 faults, I parked the scope until i had time to visit faults.
Now the scope starts to run bootup but fails to complete and the 7 seg freezes. I just need some pointers as to where to look for the cause or signals to check out (fault is on A11).
Reading comm at start gives the following:-
