Ono Sokki CF-350 ( says CF-360 when powered up )
Unit was working nicely when last used about 2 yrs ago. Now it powers on without obvious error, but does not sample. Cannot get it to accept an external trigger either. The buttons are working and one can navigate the menus but it just won't acquire any data and display it. The battery is fine and the unit had not lost the date. Nothing obviously wrong inside it either. I did not do a careful inspection but there are no bulging or obviously leaking capacitors in the power supply area, analog circuits have +/- supplies present, and +5/+12 are normal.
Anyone with a service manual, schematic, or experience repairing one of these ? If not, anyone need some spare parts ?
