Can someone help me with a broken samsung plasma tv?

Pic links below. So I have a 58” Samsung Plasma Model: PN55. It is having the clicking on and off problem. Apparently a lot of these TV’s are having the same issue. After I researched into it the general issue was capacitors going bad on the power board. I removed my board and inspected it and see no problems with anything. The board from what I have been told was replaced a year or so ago but I cant confirm that.

So my question is: What other things can I try / test to help narrow down the issue? Here is where I am at: I have the X and Y boards unplugged so just the Power board, main video board and main logic board are plugged in. The TV will not do anything with atleast those 3 plugged in. I am leaning to the main video board as the fault since I know it has not been replaced. And from what I understand the power may loop into the power board, then go into the main video board then back into the power board.

I have messed with electronics some but would consider myself between a noob and a novice, but I am willing to try anything since I will be buying replacement boards if I cant figure it out. The relay that clicks is on the top left. The power comes in on the bottom left and then out/in to the video board on the bottom right. I didn’t know if there was a way to test the voltage or something coming back in from the video board, the plug has a pin explanation next to it.

Thanks in advance for any help.
