Neo Geo AES bad picture

[Chukka]

Hi,

I have an RGB modded AES with unibios. I hadn't used it for a while and now when I tried it, the picture was all black and green and very unclear...basically not usable. It worked perfectly fine before. Any idea what could be causing it?

Thanks!

Are you sure the Scart cable is OK and there aren't any bent pins?

I'd start from there.
btw, all AES are RGB. Do you mean RGB bypass mod?
