One of two things is going on. You are missing one or two colors. Looks to me like you are missing Red and Green.
Or the game board is sending a bad image.
Check those transistors I mentioned. Put your meter on Diode check and check all 9 of those transistors. It's o.k. if they check open but if any of them are dead-short it's bad.
I don't know what H10 and H24 are, there aren't any parts on the board that are labeled with letters and numbers that I recall. Are you talking about the surface mount 10uf on the PRA-H board? If so, that isn't your problem. You ruled that out by having a stable image once you installed the other caps.
You don't need to replace any other caps than the ones in the electrolytic set. The image problem you are having now is not capacitor related. You are making great progress.

I checked all 9 transistors and they all check out fine. I agree that it seems like Red and Green aren’t being displayed. Could it possibly be the IC chip C5346A? If so, is there a way to check the chip?
Cheers,
