Display driver problem

My trusty 42 year old 41C has a display problem: when powered on, it blinks the display briefly and then goes blank. Quickly holding down nearly nearly any key shows the function or key pressed, but when released, the display quickly fades away again.

New batteries. Does this seem like the U2 is possibly bad? Or C2, the 470 pF cap? My U2 is marked 1826 0566D (Rayovac)

Anyone have insight on this?
