Lost dag on the exterior of the CRT can easily be washed off and re-applied... The CRT may be ok... more testing is needed before counting the CRT as "shot".
The dag is used as a filter capacitor for the HV supply, but its absence will usually just cause more AC "ripple" on the HV... HV is likely still present, and likely arcing, perhaps to the flakey dag or from the flakey dag to the chassis ground strap.
But it really sounds as if the flyback not the CRT is the source of the black flakes?
