Could be a fault in the drive circuits, not the tube.
If it is the tube and Toshiba will not replace it, the tech should be able
to isolate the filiment from ground by using a seperate winding on the
flyback core. Worth a shot before buying a new tv.

Entirely correct. And adding a new winding onto the LOPTF is very
easy. But dont DIY it as there are important issues you wont
appreciate unless you have some electronic knowledge.

A cathode to heater short is not too bad as it can be worked round.
