Atari 2600 changes colors rapidly on screen

[diabloarcade]

I got a Converter from Radio Shack that will convert from the output the Atari's cable is to TV cable, So im playing that way, But when i put in a game its horribly changing colors from Blue , green, purple brown, anything you can think of, in sort of a patern. It doesnt happen all the time, but it does often and the problem just got worse, no problem with gameplay, just wondering why, and if theirs a fix for this.

 

PLEASE help, as i do Not want my atari to die.

 

 

Edit:

 

To make things clear, the screen doesnt just have a single color and change it, it is whats ON THE SCREEN that changes, background, characters, whatever, so the games play, but i really want it fixed, thanks.
