I am having a problem with my pal Atari 7800. The screen flickers randomly and has a massive ghosting issue with 2600 and 7800 games.
I had the same problem with rf, and I thought that was the problem. Then I s-video modded the console and I am having the same problem.
Most of the colours are off and tweaking the pots does not help with the issue.
I wonder, could the motherboard be the problem, or is some chip problem?
I have modded my ntsc 7800 and the games look fine.
I have also tried different power supplies and s-video cables.
