Hi
Shouldn't say this, but short the heater series resistor out, and it will usually come on but it will look sick but will prove the fault.

I've had other Sonys with this fault, including some of the newer wide screen sets. Not saying they are all bad but certain ones do suffer.
I remember these tubes had poor life expectency - you will not be able to reactivate it, though.
I've tried all methods, and they all failed to come up.
The resistor is a safety device so don't leave it shorted and sell the set.
