Im using the rca service manual instructions. Did you see i linked to an rca home study course? In volume 6, there is a whole lesson built around ctc 11 alignment. And im following it to the letter, even using rca gear, except im using a regular signal generator in place of the rca marker generator. The other deviation is i did not build the video detector that rca specified. Im using the demodulator probe that came with the BK 415. Using the RCA chroma alignment instructions, i can perform step 1 ok. Its steps 2 and 3 i get no response curve for. My only guess is some stage ahead of the bandpass amp is not working. I have the chassis on the bench, not connected to the tv, horizontal disabled. Im gonna have to do some troubleshooting. Maybe conect a dvd player and see scope the video amp to see if i got signal. If so, then one of the color sections must have quit. Or the front end quit, since i get nothing trying to inject signal at tuner.
