funny colour racketboy vga cable
hi all. I've recently dug my retro collection out and wanted to hook my dc up to the tv using my vga lead I bought ages ago. but the screen now is messed up, I've done a quick google search and found the same issue listed on here in a dead thread from 2008, but the original poster is now none existant, so I come befor you gaming gods for help rather than jump onto a 7yr old thread hopefully attached is an image

Re: funny colour racketboy vga cable
I had a somewhat similar problem recently...

To sum up the problem, the green signal seems to be missing entirely from the picture. I lost motivation to test further, but I believe it is the video encoder. I think the green output on the encoder is broken. A little Google'ing came up with a few threads on various forums that suggest that the DC video encoder going bad isn't uncommon.
Here's what I did: Test the DC using different cables (RF, composite or S-Video). If you STILL have the problem using a different video signal, then there might be something wrong with the GPU or video encoder. Or possibly just a dirty AV connection. If the problem is gone with a different video signal, then try using your DC and VGA cables on a different TV or monitor. If you STILL have the problem, try using your VGA cables on a different DC. This is how I found out that my VGA cables were fine, and the problem was with the DC itself.
Outside of that, I can't be much help. I never resolved the problem I was having.
