Title: JAMMA to TV
Post by: Venger on April 12, 2002, 03:48:37 am
I posted a wlittle while back and got no replies, so I'm posting a similar post in hopes that someone can help me.

I've got a NeoGeo 1 slot MVS board(old style) and an RGB to Svideo video converter board.  I've got everything wired up, I get stereo sound, my sticks work, but I'm having video problems. Sometimes the video is perfect - except that everything seems to have a red tint to it. The real problem is that the video seems to lose sync or something. It jumps, rolls, and/or becomes wavy. I've checked and rechecked my wiring, and it's right. Has anyone else had similar trouble getting an arcade board to work on thier TV?

I've not had exactly the same problems, but similar with my supergun.
Some games just have too many vertical lines for a television to display, and so the image on the screen is crushed and skewed at the top.
I have not had colour or sync problems. I would immediatly say it's the wiring, but you say that is definatly ok, and that some of your games work fine.....
Have you tested the MVS system on a proper arcade monitor? If not, maybe some of your games are corrupted or the main board has a fault?
Good luck with it!

I have two Neo Geo boards, but I haven't tried them with a TV.  You may want to try posting this on the RGVAC board, the link is near the top of this page.

Sorry for not posting a response to your replies sooner. If anyone is interested I found out what was wrong with my NeoGeo board. There is a modification that you can do to the NeoGeo MVS to allow it to display on very old monitors that don't have a negative/positve sync switch. This mod was done to the board I have and now it won't work with the TV.
