I was playing on my dreamcast via the VGA port and after a while I noticed the screen was starting to flicker. I checked the forum to see if this has been reported before and read about some of the settings which may help.
Before turning everything back on I checked all the cables again to make sure they are plugged in correctly and there’s no damage, that’s when the image seemed to be very blue/green ish, it does seem like red signal isn’t being out put.
I plugged the vga port directly in to my monitor and that displays fine.
Plugged it back in to the ossc and reds aren’t showing.
Scart is working fine.
