Your question is not clear.
However if the main EHT drive transistor failing often check all the diodes and capacitors. Sometimes you can not check the diodes for reverse leakage. Better replace the diode with identical type and part no.

If your EHT coil is failing, buy a similar coil with identical coil resistance value. Generaly new EHT coil can not fail in a short span.

Take care while handling E H T areas. It is more than 25,000 volts A C & DC.
Extreme caution needed while disconnecting the suction cup on the
picture tube. Switch off wait for few minutes every time you attempt.
