My turn to suggest searching eHam.net, where you would find that I posted
some time back that TF1 could be the culprit.  ;^)

Finally figured that one out after the third failure.  Credit for that goes to
JA1RJU.  Yaesu itself seemingly knew nothing about it.  Bounced the idea
off K7JA & didn't get a thumbs down but didn't exactly get a thumbs up,
either.  I sense the official position will be that power supply for backlight
tube is considered a part & therefore is to be replaced outright - typical for
an out-sourced module like this.
