Samsung LNT5265fx psu both fuses blown

[hawaiianeye]

i really want to fix this nice TV. it has no scratches on the screen and it seems like its just the PSU. i can only find it for around 100$ so i would like to try to fix the PSU first before that. i dont think im going to find a 52 inch samsung like this with a good psu and a cracked screen to swap psu's anytime soon so this is a good one to learn on with a big reward (for me anyway) if i can get this going. where do you start when you have both fuses blown?

for some reason i have a gut feeling that when fuses are blown, a simple cap replacement probably wont fix it?

You need to post good clear pictures of both sides of YOUR boards.
First item to check would be a bridge rectifier or a goup of 4 diodes.
Also search for Dim Bulb Test which is useful in not causing more damage.

Any Idea if it was hit by electric surge or lightning strike.
