The knock off B boards I've seen. But a bespoke C board is a new one to me.

Whas is a 'bespoke' C board?
Bespoke is a fancy word for "custom made"

Alright, who's buying this new variant so we can know?
C board looks like the one from Three Wonders. My bet is that it's original.
A picture of the bottom side of it will clearly solve it.

This thread seems like the best place to ask. I bought one of these 'Chinese' boards from AliExpress last year. It appears to have a genuine Japanese SF2HF C board, but repro USA SF2CE roms on the B board. It arrived having taken a knock on the corner which broke the volume pot, so I replaced that and all seemed good. But after a few weeks it started showing this video 'flashing' issue. Here's a photo of the board. Any ideas what could be causing this and if it's fixable?

There’s a ton of cps1 TS info around here; try the basic stuff, swap out another B-21 c board, try the B/C boards with another A board. This will isolate the issue to a board. Yours LOOKs like a cold joint on the A01 chip. I had a similar issue and reflowing that one fixed it.

I think it's labeled CPS-A-01. On the A board.

Weird how new that 'B' board looks. Very few components on the board compared with an OG board. Is it a repro / NOS or bootleg?

I'm kicking myself for replacing a bad A board on a game at my old job (had to sell it for the money, pandemic/no job problems at the time) just for them to close down and bulk flip every game, working or not, anyway. also kicking myself for not getting one of those Chinese A boards. does anyone have a reliable source for one of those, cause ebay doesn't seem to have them anymore and I've never bought anything from AliExpress before. thank you (my CE B board has no working A board right now)

You want the Chinese A board because it's cheap?I'm kicking myself for replacing a bad A board on a game at my old job (had to sell it for the money, pandemic/no job problems at the time) just for them to close down and bulk flip every game, working or not, anyway. also kicking myself for not getting one of those Chinese A boards. does anyone have a reliable source for one of those, cause ebay doesn't seem to have them anymore and I've never bought anything from AliExpress before. thank you (my CE B board has no working A board right now)
There is a first time for everything. You'll find AliExpress isn't so bad... I mean it is but (with some effort) you usually get something close to what you wanted. They are the same sellers that are/were on eBay.
I see someone on eBay selling the whole stack for $239. They might sell you just the A board if you message them.

@mecha Ask @sheep_nova. He was able to get me some a boards with good audio. If you have a surplus b board I’m looking for something for my extra a board.

I was curious enough to take a look at one of these. They’re every bit the hack job everyone says they are. I wouldn’t have cared, I figured as much, but mine has graphical glitches throughout. Easy return (so far) though.

That might be bad connections on the Graphics chips, try re-seating.
