Agreed, Bubba: Toshiba has encountered a fair number of defective
yokes, that can be easily diagnosed by doing a DC resistance or even
ringing them. The DCU is another possibility but almost as rare as the
yokes.

Okay, what the heck is 'ringing'? That is definately a new one on me.



Using a flyback "ring tester" essentially injects a signal and counts the
number of times an inductor resonates. A shorted turn will kill this
resonation very quickly.

Should be ok with a DC ohms test though.
