Can't get RGB sync out of this board...

[Tommytamsworth]

Hello friends. I recently got a taito f3 multi.

Ive had a f3 mobo and some carts for a little while now, and unfortunately my issues are the same as back then. I can not get a full signal out of this board, best I can do is one or two colors.

I will attach some photos and explain my setup:

Axunworks power supply giving 5.07v

HAS 5.0 Supergun

8pin mini din to SCART cable

Which is going into my recently purchased RGB-2YC converter I brought from Axunworks

Trying to output s-video to my crt. I only have composite/s-video/component. Don't have the means to RGB mod atm. And my goal is for this setup to work with Y/C signals anyway for ease of setup elsewhere.

(I have some other connections in the converter image but I am not using those. Only the SCART cable is being used as an input)


Ive tried this on my small pvm and this consumer set I recently found, neither is giving me any luck.

Does anyone have any advice? I have an rgb2comp coming in soon to see if that would work...

Other notes, ive messed with video settings on the HAS to enable/disable raw cysnc and that doesn't affect the image much

Also tried:

RGB Lab's y/c HD-15 to NTSC Composite Video/S-Video adapter (Needed to do some workaround to get 8-pin to vga, got a separate converter for that) same issue, either no sync or a black and white image.

Scart to BNC into the BNC input on the rgb-2yc converter in the first image, that is what I tested after the direct 8-pin mini din to scart did not work. This one I couldn't get to sync at all...wavy image no matter what I did on the HAS or the converter.
