Color killer control on the back, and the color control on the front have no effect. I have messed with the fine tuning and not even a hint of color. Next step I think I will replace the crystal, then maybe start checking resistors on the color board.

Any thoughts? Anything I am missing? Thanks!
At some point an oscilloscope is the best and easiest way to pin down problems like this.
