Red, green, or blue retrace lines
( a quote from "Notes on the Troubleshooting and Repair of Television Sets", found at http://www.repairfaq.org/sam/tvfaq.htm#tvrgbrlin )
Where only one color is showing, suspect an incorrectly adjusted individual background/bias control or bad part on the CRT neck board for that color.
You will be greatly helped if you have a schematic for your TV set, and you may need to change some parts, clean some connector contacts and/or tweak settings inside the set, so remember the original settings before you tweak them...

I would suggest replacing the type of cable you are using. Changing the type of connection, such as S-Video or VGA or something other than what you are using, may resolve this issue as well. Because the splash screen comes up normal, this tells us that the issues lies not with the device but with whatever it is you are connecting it to. Comment back if this does not resolve the issue and we can move further.
