SSL 4000 Recall issue

[Cut Records]

Hello everyone, I am trying to use the recall of the console but it appears the screen of the recall in black and white, also the values of each knob, fader .... they vary continuously as if they had gone mad. Attached is a video where you can see.
Anyone know what is going on and how to solve it?

Thank you very much in advance. A greeting.

did you manage a full rgb picture before? this somehow seems like two unrelated issues.

about the values going crazy, a few simple things to check before really going in:
-all ribbons ok/plugged the right way? also in the console/fader bus cards?
-console setup is all correct in the computer - right amount of channels, vca groups asigned correctly etc?
-input/output test in the !tes menu comes out clean?

i've seen similar symptoms on an e series before, and it was a fried resistor on the tr buffer (in the keyboard).
