2456B whole display moved up on the CRT

 

My trusty 2465B now has a vertically offset display on the CRT. The bottom of the normal display is now at mid-point. Has anyone seen and solved this problem? Where do I look for the source of this problem?
Thanks, AL

Does this affect all four channels? If so, I would suspect a problem in the vertical output, perhaps as simple as one of the CRT neck leads ha come off, or something in the vertical chain has failed. Channel switch or vertical output hybrid.

Have you made any progress on this issue? I just received a 2465b today and it does the same thing after warming up for a while.

Good luck!
