Hitachi 55hdx62 no power to display

[mikmar]

I have a Hitachi 55hdx62 plasma that died one day. I get no power from the power supply to feed the x sus and y sus board. When I turn the power on the green led for power on lights up in the front. But I get no power out to the sus boards. I have not found Any components on the power supply that look fried. Please point me in the right direction. Thank you.
