Pink hue on RGB scart, missing green somehow?

[Gromityy]

So i've been putting together a gbsc with a v1.3 vc9900, i tested out ypbpr through pal ps2 and have zero issues.

Going to rgb scart on my ps1 though and i seem to be lacking any green, leading to this pinkish hue. i get same results running rgb scart from the ps2 with the same cable.

Initially i though it might be the cheap aliexpress rgb cable, but i tried again with a pal gamecube also through rgb scart, and while the sync was very off i still got the pinkish hue from lack of green.

It's very strange as the image coming from the ps1 looks crisp and well synced, just missing green? Opening the scart cable it seems to shows correct rgb c-sync wiring so i'm not sure where the source issue is.

I'm also using this scart breakout board, i don't think this is an issue though as i soldered green directly to pin 5 on the Scart female and got the same results.

I'm really at a loss here, all the hardware and wiring seems in order and correct, i presume the board isn't fried as ypbpr works fine.

Could be that your GBS has a problem on the green RGBS input. It looks like it was shorted out perhaps.
