Anyone have this schematic or able to tell me what the value of R401 is in a Sanwa PM1723, have a chassis with that resistor exploded so I can't tell what value it was.

Have a MS8-25far (not the model with the pcb-video board). It would start up once in 5 or so times it was powered on. Did a full cap kit (including main filter cap) and have the same problem. When it does start up (I hear the HV crackle) I don't get any picture (solid black, no retrace...

Ordered caps to do the board. On the one that now just beeps, can't get it to go to a screen at all now. Just beeps. Reseated the ram / video card. With battery and without. Just beeps.

Well I have made it worse, I pulled the battery off the mainboard and replaced it. But now when it "boots" on the second power cycle it just beeps. No actual boot. Found a manual and from that it says "reboots on startup" -> Internal battery has run down -> Contact your distributor. Well...

Got a new supply, same result. Used a 500w computer supply that boots a PC every time no problem. But same thing on this board. First power black, quick off / on and it comes up. Power off wait a couple minutes and then same thing. Hmm, wondering, the coin battery is probably bad, wonder if...

Have a linked pair of these. On power on they tend to just come up black. But a quick power off and back on allows them to boot (most of the time) occasionally I need to reboot one or the other an additional time or two before it comes u1U si Thinking power supplies getting tired? They use...

Have a Saturday Night Slam Masters with a bad Kabuki, phoenixed the board and have it working with the Kabuki from my Punisher but I only get a black screen with the existing one. I know this process puts the Kabuki into Z80 mode but trying a vanilla Z80B doesn't seem to work so I suspect there...

I have a punisher that I have phoenixed, and a Slam Masters that refuses to phoenix (but works with punisher roms). Really want to get this SNSM working correctly so eagerly awaiting word.
