No display on 54502A Scope

My scope recently stopped working and just shows a dot on the screen. I checked the flyback and I have high voltage. I don't get any clicking response when I push the keys, so it seems it hasn't booted up. I had this problem before, but turning it off and on seemed to fix it. Any suggestions?

Thanks!

The 5450XX scopes were pretty simple inside. They had a power supply, display, keyboard, and system board. The system board contained 95% of the electronics like the CPU, acquisition, display HW, and interface HW. This sounds like a HW failure on the system board. We do not have repair parts for those older scopes so I am not sure how we can be of help to you on the scope. This is probably not the answer you wanted.
