If your SMPS IC is getting damaged all the time , you can easily source an universal SMPS unit with the required + B voltages to power your TV and this will be more reliable and will not fail as the circuit is much stable.
The failure of the STR is due to poor feedback, poor components int this section or the SM oscillations, or a faulty SM transformer.
What is the Brand name and model number to your TV?
