Samsung PN51F4500AF 51" Plasma - No Power

[VividElectrode]

Hi all, I am trying to troubleshoot this set for a neighbor.
It won't power on. No standby light, no power light, nothing. I've listened closely with the back open and I don't hear any sounds when attempting to power up. I've tried using the IR blaster on my phone in case the power button was the problem. that is not working, but I also can't say for sure that I have tried the right codes.

I checked the fuse on the power board, and the surface mount fuse on the main board, and both test OK. I have a little under 118V at the power board fuse.
I don't see any swollen or leaking caps, or any other obvious issues as far as I can tell. Not sure where to go from here.
I would be very appreciative of any help or suggestions anyone could provide!

Also, does anyone happen to know which pins I can jump in place of the power button to rule out that being faulty? It has one of those funky samsung all in one buttons that are like a joystick.

Thank you all in advance! I have attached a picture of the power board. Honestly not sure why I didnt get pics of all the boards but I will do that shortly and add them.

Measure the voltage on legs of the 2 black caps on high power side of the board by red lead positive leg side of cap and black lead to negative leg with meter set about 600v. Post what you get.

I would think the PSU is faulty.....Do you have the Stand-By voltage?
