Vizeo P552UI-B2 led TV main board problems.

Hi,
I'm new to the board but like fixing electronics as a hobby.

I got ahold of a Vizeo P552UI-B2 that the motherboard is bad. I know that because I put an eBay one in it and the TV works.

This is a UHD TV so I'm trying to figure out what went bad on the board. The 12v and 5v on the power supply is on, I have 3.32 on the led_on terminal.

When I plug the unit in the power light flashes and then stays on while the unit initializes but after that when I press the power button it does not boot up.

I found one fuse on the main board but it's good.

Anyone game to help?

Thanks, Jeff

I can get pictures of the other boards if needed and the backlight isn't like normal that you can unplug the main board and the backlight comes on.
