LG 42LM620T No Power

[Ukdigger]

LG 42LM620T
EAX64427101(1.4) LG P/N: EAY62608901, POWER BOARD
No power, main fuse blown other two fuses ok
Little cap C614 in picture burnt but still reads the same as C603
I can't see any other obvious damage on either side of the board
Can I replace the cap and the main fuse or is there something else I should be checking. Any help would welcome.

Check that the mosfets next to the cap are ok and not shorted, if they are ok, replacing the cap and fuse may be all that is required.
If the cap is a 1Kv, replace it with a 2Kv

I already checked them and all the diodes transistors and the bridge rectifier and didn't find any shorts. I will take your advice and see what happens, it was a free tv so nothing to lose, thanks.

I replaced the 1Kv cap with a 2Kv and replaced the fuse and touch wood, it has been working ok for about a week now, I will update if there is any change. Thanks for your help RJ
