I have a ? on flybacks

On some monitors, no since the heater voltage comes from the flyback. On other monitors, as well as the b&w vectors, yes, since the heater voltage comes from a seperate source.
 
heater

More monitors coming out have the heater voltage coming off the power supply area and not the flyback.
 
A flyback can have more than one input coil and multiple output coils. One output coil may be for the heater voltage - and be good - while another may be for the HV coil - and be bad.

Is it possible? Yes. Common? No...
