found problem with Kortek SUM20C

Just in case anyone has this same symptom.  Problem was hula with a sharp edge that looked like an earthquake printout moving from bottom to top of horizontally mounted monitor.  Normal cap kit didn't help, but the last thing I could possibly try with parts on hand was the cure.  Replaced the cap next to the largest one(680uf) on the board.  I think the faulty one was 100uf@100v.  Also took a while to find cap #305, which appears to be #306 on the solder side, and is nearly invisible on the parts side, although it is correctly numbered.  Finally, there was a slight horizontal tear at the top of the picture that no adjustment could remove.  Jumpering the + and - neg sync cured that.  Happy capping.
