I got a colecovision recently, and only now just got around to trying it out. I thought something was wrong with it, as there was an unbearable amount of static when played on my crt. I couldn't hear any of the sound. I later went to try it on my flatscreen, and voilà, it worked perfectly; despite the resolution being less. Why did this happen, it is usually the other way around where it doesn't work on the flatscreen for these type of systems.
