Communication Power Inc FC70 need some help

[Crambone]

My FC70 stopped showing the lower digits on the display across the board. I pulled the display board out and retouched all the solder joints but still same issue. When I power off and on the bottom digits show for a quick second but then go out.
I don’t have a schematic and can’t find any docs on this unit?

could also use a copy of a CP400 Sams guide I believe it’s number 268?

Try these.
I am pretty sure that @tramdr posted them a few months(years?) ago. Thank you TramDr!

Tramdr didn't post that, I did. Here's the manual that I also posted with those others about a year ago.
