Ive got a wood grain Atari Video Pinball C-380 that used to play in normal color but now only comes up in Black & White. What would cause the color to stop being output? There is no Color / B&W switch on it. It is set up on a manual 3 position switch box that works fine. Picture attached here of it working in a built up Atari Console rack I put together for the Museum of Art and Digital Entertainment museum - The MADE - an all playable Video Game Museum in Oakland, CA.
Any ideas?
