If I remember correctly, that has a mess of 6.8ohm 2watts around the STKs.
You might have some off value. Also, I've had coils open or raise coming off
the power supply input.

Take a close look at the solder side of the connectors on the convergence
board for glue that is medium to dark brown in color, no matter what remove
the glue as it does become conductive and cause intermittant misconvergence
and mis focus.
