I found no configurable jumpers at all on the display. There is a large ribbon cable and a small ZIF header cable. I reseated both, and the display corrected. Not sure if it long term, time will tell.
Thanks to all that replied.

It fixed itself and worked for a few weeks. It happened again today. I will have a look and see if I can find these jumpers and report my findings.
Thanks!

IFR-1900 Receive IF Module
I have an analyzer that exhibits low levels. The problem has been isolated to the RX IF block. With no schematics and no support from the manufacturer, I am on my own and going nowhere fast.
