Not that I am into mending any tv sets! Just an observation on my part, I hope you don't mind?
Where I used to work, one particular model of air traffic control receiver had a custom built mains smps. We had to replace the start up resistor with one rated for sufficiently high enough voltage rating. It was also stood off the pcb using ptfe sleeving, to assist ventilation. I was involved in trialing this with our qa department. The electrolytic capacitor in the start up circuit was replaced at the same time, along with 3 other capacitors.
