Sharp LC-39LD145K No Power to LEDs

[Easky15]

Hi all, Been a while since ive had to use this forum,
I have here a Sharp LC-39LD145K that works fine apart from no power to the backlight LEDs, I have stripped it right down and tested all LEDs and they all work fine, I can see them flash briefly for a split second when powered up, the voltage to them slowly drops away after the flash so im guessing there is an issue with the power board,

I think the model number on that is 17IPS20 and here is some pics of it

Any help on this would be greatly appreciated,

Thanks

You have a few leds not working. Check the video and pause it at the flash.
