Anyone seen this? Toshiba HDTV CRT dead?

I did a house call on a Toshiba 36HF12 that the complain was no
picture. I had repaired this about 6 months ago for vertical
shrinkage, and it's been running fine till now.

It develops 32KV HV, filament, 250 kine supply, G2, and all secondary
diodes sources off the fly are normal. The cathode voltages on all
three cathodes are high rail. I didn't have a scope with me, but the
60hz vertical "growl" from the yoke is unmistakable, so I know it has
vertical deflection. The G2 voltage varies from 200 to 850VDC.
Carefully raising the G2 to maximum induces no light whatsoever on the
CRT.

I brought in my old B&K 467 and hooked it up to the CRT with clipleads,
and the tube reads DEAD, like maybe the G2 or G1 pin is disconnected.
The TV is just over 2 years old, but the customer is going to try to
see if Toshiba will cough up a CRT.

Has anyone seen one of these do this?
