If you had good color and it was strongly in sync (no barberpoling), I would be less prone to suspect the crystal.

Hi Bill, thanks for another idea to look into. I will do some more experimenting with the set this weekend and log a specific list of what is displayed on the screen. My mention of "bleeding" may not be a very descriptive term. Basically, when I turned the color killer clockwise, I saw hints of color in odd places like the lights on top of a cop car, but black and white in most other portions of the raster. These places were the wrong color with too much amplitude. Yes, the picture was strongly locked before as seen in the pictures.
