Opened up the SE today,
wow, 2 of the 4 solder joints had significant cracks all around, one seemed to have a thin/hair line crack that made a full circle around the joint. This was all visible w/ just my reading glasses. Under the magnifying glass it looked horrendous. So that was good to see, ...I got most of the old solder off I could and re-flowed new solder, put back together and problem is no officially solved. Screen looks 100% stable.
While I was checking solder joints I noticed several other areas that looked like they had cracks too, so while I fixed that one joint I did a few others as well.
That C15 cap looked good to me, but not quite as flat as I like to see these old caps. It isn't puffed or anything, but just didn't seem quite as flat as the other cap's on the board. Yet that may be me or just may have been how it was manufactured. I just like to see the tops a bit concave to flat. In any case I will order a replacement and re cap that one next time I have the machine open just for good measure.
