The cap replacement has fixed the ripple and had made the issue much better, but the issue is still persisting. I did however, notice something interesting. I was fiddling with the scope and bumped the trace finder, which caused the screen to go back to normal. I pressed it again, and it was normal, but when I let it go, the issue was back. My trace finder is rather rusted, so does this point to an issue regarding it that would require a replacement or could I fix this with something as simple as bending the tabs?
EDIT, When pressed while the screen is compressed, the trace finder still compresses the vertical, but the horizontal is untouched.
