That's not the retrace cap - that's the B+ bypass cap off the flyback. The retrace will be a 1500V film cap. If B+ bypass cap opens, the pulse from the horiz output will feed back to the regulator and cause start up and shutdown. While it's possible, I don't see retrace caps fail in anything but a binary fashion (good or bad), but I do remember one particular RCA that used a retrace cap with two or more sections in series. One section shorted, the value of the cap increased, the HV went down and the horizontal scan went very wide. That was the only one I remember that went off value.

Sounds like you're down to proper set up and a weakish picture tube.
