So I have a four slot board I've been restoring, new battery etc. Everything is working perfectly, but I'm noticing some noise on the RGBS signal when I compare it to a single slot board. Any idea what the cause could be? Same supergun, same power supply, same cart, same display. Noise on the four slot, not on the one slot. Thinking it MAY be a grounding issue... there was a green grounding wire on the frame, which I removed since it's not going into a cab.
Any ideas would be appreciated. It's not a very noticeable thing, but it makes my brain itch.
