SNES console showing wrong colors via multiout

[kikenovic]

Hi everyone, I have a SNES first model (detachable SPU). Hooking it up via multi out the colors are wrong, like in this example



I tried known working AV cables with the same results.

Via RF the colors are fine. Greatly appreciate any advice. Thanks.

If the colors are fine via the RF connector then it's possible the multi output itself is bad. How does it look physically? Is there a lot of rust or corrosion on it? If you have another SNES around you could try desoldering the multi output and swapping it and see if there's any difference.
