I have an HP 54600A oscilloscope that is having some problems with the display. The vertical axis of the screen seems to be squished and slightly distorted. The image is about half as tall as it should be, and slightly stretched on top. I've disassembled the scope and adjusted the "V. Size" and "V. Lin" POTs, and they help a little, but they don't have nearly enough range. Does anyone have a schematic of this oscilloscope? Does anyone have any idea as to what could be causing this problem?
I've attached an image of the screen, I apologize for the poor image quality, I didn't have a real digicam around, so I took the picture with my phone.

It looks like you are loosing high voltage. We purchased the display from a third party vendor. I have a copy of their schematic that you can use. Agilent does not stock any replacement parts. Sorry. We replaced the display as a complete module. Maybe the attached schematic will help you out. The schematics for the 54600A are at the below web site.

Another copy of the display schematic is there also.
Let me know if you have more questions.
