Need to Replace Convergence Pot

They have been cleaned twice, but I get what you're saying. As it is now, I can't get the same results twice when adjusting. The first time I tried, I had a few bad converged areas and lived with it. Years later I did the same procedure and it was almost perfect. I then tried to touch up those areas, but couldn't and then couldn't get back to where it was before and now have even more areas that are off. I only made small changes based on the area and the pot that controlled it and still they didn't allow adjustment back to where it was.

The only thing I can think of is pots that are not up to the task anymore.

The oddest thing I ran into was during the static convergence. I moved the blue away so as to align the red and green. I got it dead on, but when I moved the blue in, the red and green would separate as soon as the blue got near the center of them. I could see the red go up and the green go down. I had to compromise on the blue a bit to where the red and green came back to their original positions. The dot is pretty much white in the center with a bit of color around the edges as I'm sure it is supposed to be.
