I was making a new RGB cable for my AV7000 today, and in checking the pinout of the machine I must have short-circuited something or done something else weird, but basically I now don't get a synched picture on my monitor from the RGB output.
The cables are fine, the monitors are fine and the games are fine, I've checked them all on a Raijin and that outputs as normal.
The S-Video output from the AV7000 is also fine, I get a perfect picture on a normal television.
Has anyone seen this before or know how to fix it? It looks like I'll have to send it away for repair, though I'm not sure to whom I should send it - should I ask MAK or Sigma themselves?
I also made an adaptor for my ST so I can use MSX joysticks on it today, so at least I have that to play around with.
