I have an [Agilent] MSO-X 3014A scope that doesn't seem to completely start up. I bought it back in 2013 and it's had no use for the last few years but when I just tried to power it up the display stays dark. I see the various green light flash on and off, then "Math" and "Ref" indicators stay on while the display is black the whole time.
Has anyone had a display problem like this? Is this a problem of incomplete startup? Anything I can try, like a reset/reboot to see if the display can come back to life?
