Vertical Test Group Self Test Failed on Agilent MSO8104A

[admiralmaggie]

I'm getting "Vertical Test Group" Failed on my Agilent MSO8104A. It does not provide any other information at all. The service manual says it should specify exactly which test under Vertical Test Group failed but the error log doesn't say anything other than "Vertical Test Group: Failed". All other tests are passing and scope appears to be functioning properly. Any thoughts on this?

Here is more details. I found the log file. All values look nominal... Any help is greatly appreciated:

UPDATE: I ran Self Calibration a few times and it passes but the pesky Vertical Group test still fails... Any suggestions?
