test everything with continuity or the beep setting whichever you have on your meeter.
those parts should all read open in circuit except C62 that will read shorted in circuit test it out of circuit to see if its shorted or open. you want it open out of circuit.
if all else fails i have a fully rebuilt 25" full cap out with new fly.
pm me if you want to trade that in on it.
i also have 19"s with a full cap out with new fly.
and one's with the old fly's if you dont need one with a new fly on it.
just for grinns check the 6 rectifier diodes again to be sure.
also check and unplug your marquee lite as you said that you swapped another chassis into the game and it blew fuses to.
something doesn't seem rite to me. maybe you have a short in the cab that's getting to the monitor. does the game play blind without the monitor plugged in??
good luck on finding your problem keep us up to date.

here's some tl;dr, but people ask for details so here goes... the 7191 in question was pulled from a T2 cab we've since sold... I used that tube + one of the chassis I pulled from this Suzuka to go in my MK2 cab since it didn't come with a monitor, and that was all I had at the time. it's nothing to do with cabinet wiring on the Suzuka, or any of the other games, since the K7000s in those all work fine. I found this one literally dangling by the neckboard in the T2 when I got it in a trade deal, so who knows what happened to it before I got it.
this 7191 has been tested now in 3 different cabs. my Street Fighter cab had a 7171 in it that got a hole blown in it from a dead flyback a couple years ago that I'd managed to repair, to the dismay of probably anyone that's heard of its legend on here lol.. but yeah, the only easily accessible cab I had to try the 7191 in after I replaced like everything was the SF cab, the 7191 didn't work and made this noxious burning plastic smell (probably from the cracked resistor, R301 is it?), so I put the 7171 back in and the same shit happened! it was weird, but that probably had some pins that grounded to the frame, why I didn't think to cut those when I performed surgery on it, I don't know.
I'll take a gander at those other caps though. the diodes I all pulled entirely out of the chassis to test, only got current one way, and of course I reinstalled them in the correct directions.
I did some searching on google earlier and over at arcadecontrols someone suggested checking a C69 too, "if it had it", this 7191's very different from the 7171's I'm used to seeing, it doesn't even have the 50/60 pot on it. could this have a C69? I looked everywhere and couldn't find it.
