Need manual/schematic for IO-4540

[Chris KX0Y]

I need some help with this scope.  I have no documentation for it and it has
a strange problem.  There is no display, but when the power is turned
off...for a momnet an ellipse can be seen on the screen....it then veres off
towards the bottom and is gone.

Thanks,
Chris
