Video boards on predictas rarely have issues, no paper caps there, and resistor values are generally not critical. In fact most of the resistors can be off a lot and still be fine.
Generally speaking if you have a lot of exp with diagnostics you can get away with shot gun replacing. If not you are best to base line and then replace a few. Of course with a predicta pulling the PCB is a bit of a pita, but often you can just unstake the grounds and lift a few wires to get access.
I also like to base line a set to determine its overall status before touching it, and that includes cleaning it. I have gotten sets that's that were real dogs due to a single misplaced cap on a botched recap.
I have a series on a 10L chassis, there are several parts. You may find it interesting as I talk about my approach.
