      I picked up another power supply for testing and the problem persisted so I’ve eliminated that anyways.

        I’ve test multiple other 240p component video sources (SNES, N64, PS1, Genesis) and they all worked fine. I just don’t have another 480p component source to test.

        However, I just thought to test 480i video sources to see what I could find there. Somewhat unsurprisingly, when I set the Wii to 480i I still saw the horizontal lines, but what was interesting was I was able to replicate the same horizontal lines from the N64 when running a game that outputs 480i (which is somewhat rare but luckily I have games that do so).

        So, this tells me that there’s a high probability that the issue lies with the OSSC (or its power supply) on 480i and 480p component video sources. Which means it’s likely the power supply, the HDMI mod I did, or some other component of the OSSC. Would you agree based on these tests?

          Oh the other thing I forgot to mention is that I tested bypassing the OSSC (ie. by plugging the Wii component cables directly into the TV (Samsung UN50MU6300F) and a monitor (Dell 2407WFPb)) and I didn’t see any scrolling horizontal lines. At first I assumed this proved the OSSC (or its power supply) was the culprit, but I then had the thought that maybe the TV and monitor are both performing some sort of post processing that removes the noise from the signal? Is that possible?

            They’re straight

              My Wii doesn’t have any display outputs mods like an HDMI mod, though it has been modded for homebrew if that’s relevant.

              Unfortunately I don’t have another compatible PSU I can try, nor do I have another 480p component output that I can try to eliminate the Wii as being the culprit. I have tried different component cables which made no difference so it isn’t those anyways.

              If you think those things are the most likely causes, I can certainly look into trying to test those things?
