Got this board from DaisyAge simply for testing a method of flattening a MV-1B by just swapping plugs on the main board (SUCCESS, I posted about it in the tech support thread).
DaisyAge was kind enough to give it to me for the price of shipping and did let me know what it was a bit "funky". Seems to work ok but the video is tinted red. Crosshatch and basic setup/color test menu all work and all 3 colors are present and everything is clear, but there is a distinct red tint to the whole screen, and notable in the background. It's never black, always deep red. If you unplug the red line (running straight RGB to a PVM) the background is perfectly black as it should be. I have plugged other NeoGeo boards into this PVM, they all display correctly so it's not the TV.
This was present before I switched plugs to flatten it, and no wiggling of the plugs, or board twisting, or chip poking makes any difference. I inspected the board under a microscope for broken traces or anything, and while I might have missed something, everything suspect seems to actually be ok.
Things done to board are 5v Mod, and battery mod (although the battery is currently uninstalled. Original Bios is still on there.
I mentioned funky text because when I plugged in a 161-in-1 cart to test things there were bits of text missing, like a few pixels from each character. Although I did not do extensive cleaning, wiggling or anything to see if that went away, or tested with a official cart, so that might not be a real issue, but thought it needed mentioning.
