Front panel matrix diodes all look good, so I suspect the 74AC11244 drivers.

Correct Answer

Sorry, they don't exist. This was a board-level repair device. If you sent it to the Service Center, the bad board was isolated and replaced. The old board was scrapped.

 

The Service Manual is here: http://literature.cdn.keysight.com/litweb/pdf/54615-97019.pdf?id=1000000342-1:epsg:man
