I had one of those, back before the economy crash of 08, same clicker remote. i loved that little set. drh4683 has a nice walk-around video of that set on his youtube channel.

I seem to remember mine had a similar issue, in mine it was the little switch on the chroma board i flipped it back and forth a few times and the color came back. YMMV
