If there is shielding to prevent a burning flyback from destroying the TV, that's fine I guess, but the poster of this topic indicated that his TV was destroyed.

The reason why flyback transformers were all gooped up with wax was as much an acoustic consideration as much as a high voltage insulator. Without the wax to deaden everything and keep the windings from moving around the coil would've sung at that infamous high pitch of the horizontal sweep until every dog in the neighborhood would go berzerk. As it was they'd sing loudly enough.

For a flyback to burst into flame there must have been something very wrong with the sweep circuitry in that set.
