So frustrating, I replaced R-172 and R-173 as they had both gone open and I still have no color. I have a good black and white image but zero color.
When I adjust the color killer I get a momentary change of hue, but still stays monochrome. Hue control does nothing. The AGC threshhold control in the rear does nothing either.
I had changed out C144, c145 and C151. I guess pull the chassis and investigate the color killer..... Hmmmmmm......
Geeze how did I miss M8? The color killer AGC diode.... Its just a switching diode and I've still got a pack of them in a drawer.
I'll replace that and check some of those resistors in that circuit.
