This is my first Zenith. I rescued it from an electronics disposal center. I am very impressed with the sharpness of the focus and dot pitch of this TV. I now understand the appreciation for the Chromacolor II delta gun picture tubes. I need to adjust the dynamic convergence, but when I do, the picture will look even more sharp.
One issue that I am having with it is the contrast seems to flicker between a very low contrast and the contrast that I have the TV’s “picture” dial set to. What is causing the contrast to cut out like this? If I adjust the picture dial, it typically causes the contrast to flicker back to normal.
