Help with Toshiba 32av502r power supply

[Wbfinley]

Hello badcaps community! I am new to the forum but I hope I can become apart of it in time. So I am semi-new to electronics like this. I am tradesman so I have some good fundamental hands on skills but I need your help. I have a Toshiba as per the previous mentioned title that I believe has a power supply problem. I had a power surge in my home recently and this TV was left out of the unplugging party. I have removed the back and it reviled a blown fuse at the AC input on the power supply. I replaced the fuse but when I reattach the 110 cord, even before turning the power switch, the fuse blows, consistently. So as soon as the 110v comes in, the fuse blows. I have not done a repair of this depth in small electronics before but I believe I can follow advise very well. Can anyone point me in the right direction?
Any help is much appreciated. Thank you!

I have ( I think) attached an image of the Power supply. The number on it is: 01-pk101v1070i-vapim-917-1216-00a

I would check the bridge rectifier. The black thing on heat sink with tester in diode beep mode no power hooked up. Across each pair and reverse leads do the same. Meter should not beep. Also you can check across input terminals should be no continuity.

When ever a fuse blows, it highly possible that it dies with the bridge rectifier (shorted), the short circuit resistor protection (blown), the switching MOSFET as well as the PWM IC driving the MOSFET -- check for shorts using diode or resistance test of your multimeter.
