Ok. My fellow Amigians… I have been troubleshooting my issue and have found something interesting. When I run the ZZ9000 card without the passthrough ribbon cable, the screen is awesome! The minute I plug in the ribbon cable and use the video port pass through, my screen is flakey and flickers.
So, with that in mind. Is there anyone on this forum that has a good understanding of the amiga video circuit? I am going to scope this out and see if I can find the noise. I would bet my money on a bad cap or bad ground somewhere in the video circuit of the A2000.
Please let me know if this helps. I will continue troubleshooting my issue and will post my findings here.
