Today I was motivated enough to work on my Sega Turbo project. I pretty much gutted a machine and have all the parts on my workbench. I've been troubleshooting some board and steering issues, however my nanao monitor was working beautifully, crisp color, sharp as hell, I was very happy with the monitor.
Well.. While I was checking voltages on my board, I saw that the monitor turned solid green. After shutting off and restarted, still solid green.
Thinking it was the pcb, I plugged in my test monitor and video output is working fine. Unplugging the monitor from the board while leaving 100v power on, it seems to have no effect.
I pulled the chassis and checked for shorts, burn marks, etc. Everything appears to look good with nothing blown up. I thought it might be the header pins but continuity to those checked out - wiggling them has no effect. I also checked the header pins going to the neckboard and going to the yoke. All appear to have continuity and seem solid.
I'm pretty pissed especially since it seems like it was something I did, but its not obvious to me how checking voltages on the the pcb somehow blew something on my monitor. I guess I should have just used my test monitor.
Regardless, I would really like to get this back up and running. I have a feeling since it was working like a champ a simple cap kits not going to help. If it was a WG-4600 or a G07, it wouldn't be a big deal to swap out, but finding a replacement chassis for this nanao monitor will be hard so I'd really like to figure this one out.
Its possible I shorted the RGB or Sync wires, if that was the case - what components should I check?
Not sure where to start. Please help!
Thanks,
