Ok, let me give it a try 
In my opinion there is a problem in the signalhandling for B. R and G seem to be present, but they are heavily outshined by B.
Is this visible even if the signal line is disconnected? Put the Drive-adjuster in the middle position. Then all three Cutoff-adjustors on minimum, so that you have the highest voltage at the cathodes.
The picture has to be dark, B will not be high enough at the cathode... color output state (?!) defect? Or maybe a transistor in front of it...

Also ich meine, daß der nen Stich in der Videosignalverarbeitung für B hat.
R und G werden ja wohl dargestellt, aber von B hoffnungslos überstrahlt.
Auch bei getrennter Signalleitung sichtbar? Die Drive-Steller auf Mitte stellen.
Dann mal alle drei Cutoff Einsteller auf Minimum, also höchste Spannung an den Kathoden....
Bild muß dunkel sein, hier wird aber B nicht hoch genug an der Kathode werden....Farbendstufe defekt?
Oder einer der Transistoren davor....
