Hi,
I forgot to mention that i had an old TV once that i liked and did not want to throw it out, but the front end power supply blew out. Lucky it was just a rectifier diode, but later the high voltage flyback transistor blew out. I found out the transistor had a very high voltage rating and the highest voltage transistors i had were something like 450v, so i used a very unusual connection of four transistor CE junctions in series with special base drive arrangement to find out if it would work again. Sure enough, it did work up to a certain voltage (i did not want to go too high with that arrangement) but then i chickened out because a replacement transistor would have cost something like 25 dollars, and i did not want to spend that much if i did not know why it blew out in the first place. I suspected it was because the heat sink became a little loose, but who knows. If i bought another one and it blew out a week later, it would be a total waste. So i put the money toward a new TV that came with better features.
I am just mentioning this because if you do repair it and did not replace a single part that caused the failure then it could blow again, so it depends on the cost of the repair if it is worth trying or not. If it does blow out again and the parts are not that expensive, then maybe you can try a second time after replacing more parts.
When my older PC power supply blew out i checked ALL the capacitors just to make sure. Some of them were bad so i replaced those plus a few more with quality parts. It's hard to tell if a smaller cap is bad sometimes, and that alone could cause a failure.
A real long time ago i used to fix home entertainment stuff for people as part of my living. Then i used to replace whatever i found bad, and if it worked then i called the customer and they came and picked it up. If they had another problem because something else was wrong then i would fix it for free the second time after replacing more parts that were either bad or could have been bad but where hard to test in circuit.
