I fixed one of my SE's this year after it suddenly lost video completely.  I think it was C15.  No cracked solder joints that I could see.

Good work on the fix.  It is interesting to see how the community has changed when I joined over a decade ago...the supply of good parts was available and cheap!  So not much actual electronics diagnosis and fixing was happening, unlike today.

-Hey, C15 is what I was going to look at next, but didn't have to.  However I would like to have a replacement on hand for C15 as I hear that this one goes out often on the SE's.

Do you recall what type of cap' you used to replace C15?

Would this be suitable:

It is kind of nice in a way that we can fix our computers piece by piece rather than replacing entire components, ...makes this hobby more fun in my opinion.  Otherwise it would be too easy!
