I'm working on the display board. I mistakenly installed the wrong chip in the IC 9 socket and smoked it.
I got the right chip in today and installed. Now I'm blowing the 1/4 amp HV display fuse.
No doubt I took something else out when the wrong chip fried.Just don't know where to look.
The fuses doesn't blow when the board is disconnected.
Any help appreciated
