Page 26. I'll post a picture of the area of interest in a moment.

Little bit more detailed description of the layout and problem:
This monitor is built modularly, where video is processed (=amplified) on a dedicated board.
This video board connects to the motherboard for power and some serial, but these connectors have been an issue. They flex and scrach, and these monitors even new would start to have rather serious overshoot/ringing issues caused by what i assume is resistance in the connector. And I've pinpointed it to be specifically the 12v rail which indeed goes to the preamps and main amps.

And yes, I've already tried various forms of deoxit, and it IS effective, but only for a day or two.

Okay at least I have the correct idea. I'm literally learning this shit on the fly here. But I'm wondering what size of cap I'm even supposed to use here, that ripple is like >100mhz.
