Stuck on another zoom call still. Decided to clean the 34401A. Looking pretty much factory fresh now!

Cleaning recently acquired test gear while stuck on conference calls used to be one of my vices. I now just avoid conference calls...

So this panel is actually designed to be able to service the LED BL array...?
HALLE-FUKKIN-LUJAH!!!
These LED arrays are driven CC in series; they separate them in banks and modulate the drive current to different zones of the screen for higher "dynamic contrast" compared from one part of the screen to other parts. I'd guess that the two banks on each side drive alternately to be able to keep dwell time lower; either that, or each bank is aligned with a different diffraction lens so it corresponds to a different quadrant of the screen. :-//
