Update March 29. I did mark the AFT adjustment located on the main board and tryed to adjust it made no difference to the color but did improve the picture quality by a hair. Next I checked to make sure the color and tint control had a good connection between the main board and the user control board. Had no problems there. Next i checked the components on the input of pin 13 on the chroma luma processor chip could not find anything wrong with any of components. Not sure we're to go next but if someone would be willing tell me what troubleshooting they do for a tv that has color not working or can point me to were I can obtain the information. I have done a lot with this TV and I don't want to give up on it as feel it has some many good years left but I have worked on it for 8 months so I'm getting tried of working on it and I am kinda in rush to get fixed as I'm moving on May 9. If the TV is not fixed by then it will be a long while before I can get back to it.
