Since a few days the monitor of my Olivetti M24 displays a bright spot in the middle of
the screen when the system is switched off. I suspect the screen will be soon damaged this
way. I know there is a circuit in CRT monitors that prevent this. But I don't know
where to look on the circuitboard. I did check the parts on the print on the tube base:
they seemed to be alright, so now I'm stuck. Does anyone has a clue for me how to
proceed?
