    my d75 turns on ok. runs several (10-15) minutes, trace fades away. I think the power supply is failing, but have no schematic. This scope has been idle for months and I suspect some electrolytics are failing.
    Turning scope off for several minutes recycles things and it starts anew.
    Boat link does not have a d75 schematic, any help out there? Tom Poteat
