Dear,
I bought an old SE/30 for server-purposes, but sadly it has a video problem. I see only a fine horizontal line. The vertical sweep circuit on the analog board doesn't work, but all parts on the analog board are ok.
We detect the problem on the logical board. The UI6 (341-0665-A) seems to be defect, because there is no trigger on pin 4.
It is a PAL16R4B; must they be programmed bevore replacement ?
thx
antonio
