Tony;
It is a problem...and this includes Toshiba.
The actual "thickness"of the main board has been
trimmed.
You may have noticed that most Chinese/Korean
products, no matter what the Label that goes
on..have added a screw hole to mount the Flyback
transformer to be supported by a screw thru the
back cover.
Circuit boards have gotten so thin, that the
weight of the flyback has to be supported by other
means.
My favorite expression..."How Sad".
