LG Plasma TV Click-Click

Good evening,

I received a LG plasma TV that makes a clicking sound once plugged in.
The light is red.
When I try to turn it on, there is no reaction, not even the light blinking.
The clicking starts as soon as I plug in the TV and stops when I unplug it.

I looked into this problem, and on a forum, a guy had the same issue and he changed 3 resistors and it worked. I tried it, I changed them but nothing, still the clicking and it still won't turn on.

The TV is an LG 60PK250-ZA.

Well, I wanted to upload photos but CCM told me: NOPE: https://www.noelshack.com/2018-04-1-1516655803-capture.png

So I'm using noelshack...

The sound comes from the components circled in red in the photo: https://image.noelshack.com/fichiers/2018/04/1/1516655853-photo-2018-01-22-21-57-51-edit.jpg

I also noticed that if we unplug the motherboard: https://image.noelshack.com/fichiers/2018/04/1/1516655935-photo-2018-01-22-21-58-01.jpg
the clicking disappears.

Should this board be replaced?

Anyway, thank you in advance for your help.

Best regards, Amako ^^

    Hello,
    The components highlighted in red appear to be relays and the clicking sound is likely due to fatigue (they no longer "stick")

      Good evening,
      can we test a relay like this one? And if so, how?

      Best regards, Amako ^^

      I tested the relays and that's not it...
      Could it be the motherboard, then?

      Best regards, Amako ^^

      Possible, but getting a quote from a technician (not easy to transport a 60-inch plasma... I have an LG 60PM670S that weighs over 40 kg... not to mention the size) considering the age and that darn planned obsolescence, it's not obvious that the parts are still available.
