[Test-Equipment] Scope help needed!!!!

[J. Forster]

Where on the screen is the vertical line? Left? Center? Right?

What are the readouts doing? Are they displaying as lines of text or just
short vertical lines at the top and bottom of the screen?

If the latter, you likely have a mainframe H amp issue.

First step, check the power supply voltages, per the manual.
