Hi, I have some problems with a Neo Geo MV1-C that I have consolized. The RGB cable I built does not work 100%. It shows normal startup graphics output when I turn on the MVS on my Sony CRT but when the horisontal and vertical bars shows up (if I do not have a game inserted) the screen goes black as if the display is lost. The same thing happes if I boot with a game inserted. Its like the display output is dropped once the game is supposed to run. But when I run the MVS on my Sony flat screen TV instead then the display is never lost! Instead I get a rolling image of the game so the game is running and there is display output all the time but it is not stable, looks like a f"n sinus scroller from an Amiga demo. I tripple checked my RGB cable and it is based on this one: http://www.neo-geo.com/forums/showthread.php?220333-Jamma-to-Scart-question I tried taking ground from pin 14 and pin 2 and there is no difference. On my SCART-plug I got, red, green, blue, sync, 5v, left channel and right channel (did not bother with audio ground before picture is working), ground is connected to pin 5,9,13,18. I put a 100ohm resistor on red/green/blue and sync and put a 100ohm resistor also on pin 16. I assume something is wrong with the sync line, but what can be wrong? Do I need another resistor or something? Maybe the MV1-C is broken, however I can see the game running on my Flat screen so I assume it is something I have missed on the cable.
