Zenith Chromacolor II "Ghosting" Problem

[ghjkl67]

My Zenith television with a 25EC58 chassis has a ghosting picture. What I mean is NOT multiple images. You can see in the pictures that the people have a distinct black outline on the left side and a white outline on the right side. On one of the pictures, you can see that the horizon actually goes through the person's body in the foreground. Somethimes, the outline thickness is enough to completely wash out a small image, such as subtitles on TV commercials. I noticed that this problem mostly comes up when there is a large contrast of light in a single frame, such as adark object on a light background.

My guess is the AGC Delay, but I tried adjusting it with no success. I noticed when I move the dial all the way clockwise, the outlines become thicker (with a fuzzy snowstorm). Also, the intensity varies depending on what picture is shown. I hooked up a cable box to the TV, and the picture looked fine when I turned the weather report on. When I turned on a hockey game, the picture got completely washed out. When I connect a VCR, the picture almost always starts to "ghost". Another reason I think the AGC Delay is part of the problem is because the picture tends to swerve at the top of the screen. Again, instensity depends on what movie I put in. There is no problem with the tape or VCR (it was tested on another TV). Occasionally, the picture divides the colors into horizontal stripes across the screen (see picture). I usually fiddle around with the tuner and AGC delay to fix it, but after I fix it, it appears again when I change the channel momentarily, and back again.

Please note that the color issues and swerving picture are not major problems, they only come up from time to time. I thought it may help knowing that to diagnose the initial problem (the ghosting). Also, the AGC Delay might have nothing to do with it. Based on what I know about this TV, it is just an educated guess. Please let me know your thoughts on how to resolve this issue.
