Samsung Power Supply Board

[myeeth22]

Recently, I pulled a power supply board out of a smashed Samsung LCD tv. The rest of the TV's junk, but the power supply board is in good condition. No cracks, everything looks fine. I plug it in into the mains, (US) and measure the output on the pin headers, red probe on 24V, black probe on GND. Nothing. 0V. Multimeter's set on 200DC, should be fine. I check the 5V out put in the same way. Nothing. Ok, I check the fuse. Fuse's blown. Grab some new ones (250V, 5A), pop em in, and measure again. Still, nothing. Again, I check the fuse, it's blown. WTF? All the caps look good, no bulges, they're United Chemi-Con  brand capacitors. The board in general looks good, no obvious faults. I'm at a loss here as to why the fuse keeps blowing.

I'll post some hi-res pics once the camera's battery charges.

As I just wrote in another post

Some people say fuses die on their own or due to age or fatigue.  In my limited experience in troubleshooting, that has never been the case.  If the main fuse popped, the usual suspects are shorted bridge rectifier, shorted power mosfet, etc.

This is https://www.shindengen.co.jp/product_e/semi/list_detail_NEW.php?category_id=01&sub_id=03&product_id=D10XB60 bridge rectifier, and I see no physical shorts. I'll have to check the mosfets, but they have no physical shorts either. How would I test these?
