Still trying to figure out the color porblem. In the Sam's it has this information about troubleshooting the video buffer/Comb filter which this set doesn't have so I skipped that part. Also I did test Q153 and it was good. The AFT is done between the first video and the microprocessor on the MCU tuning system and there is no adjustments for AFT. Before I continue I have been using a Sega Genesis with the OEM RF adapter. The game system with the adapter works on all of my other TVs with RF adapter perfectly fine. There is now way to turne of the AFT but I think there might be adjustment I will need to look in the Sam's. However I don't think tunner and the video If are bad as I get nice picture with no snow or interference and clear sound just no color at all purlye monochrome as if the color killer is always on. There is no adjustment for the color killer so can't tell if that's giving a porblem. I'm afraid when it comes to color TV circuitry I'm pretty losed. I have included parts of the schematic that center around the IF and the NEC 303-1 IC. I like figuring things out on my own but I have spent hours looking at schematic and testing some parts I thought might be bad. Maybe someone will find something I overlooked. If not I will just try swapping out the NEC 303-1 chip with an NTE1416 if nothing changes then back to the drawing board. I know to most me talking about this

Thats all folks
