Hi
I am consolizing this MV2F board, but am having an issue with it. I followed Xian Xi's guide: http://www.jamma-nation-x.com/jammax/files/cmvsmv2f.pdf and it works for the most part, however:
- I am using a neobitz encoder for the video part, the one that has composite, s-video and component outputs, however here is how the video looks in every mode:
1. Composite:
It looks nice for the most part, however vertical edges are so wavy.
2. S-video
Quality image looks right, but there are like jailbars or interference, most notable in the red and blue colors:
3. Component
Looks like crap:
So far, I have ruled out:
- The power supply: I tested using the PS from my supergun at exactly 5V, same results
- The MV2F board: Works perfectly when using a supergun
- The encoder: Tested with a spare one I have available, exact same results
So...any ideas guys?
P.S: I also noticed the voltage at the JAMMA edge, when using the suggested 3A@5V power supply is about 6V, which is way too high. I believe this is because the board does not draw too much power, therefore the 3A@5V unregulated power supply is too much for it. Should I get a regulator, like this one?http://www.ebay.com/itm/DC-DC-9V-12...343798?hash=item4d37a99a76:g:RRgAAOSwu4BV6hTV any other suggestions?
Thanks for any pointers
