Where can I get a control board for my HE550HUD-B31/JM/72104002 Panel

I have a bricked Hisense 55” 4K Tv, but the panel should be fine.

ANSWERS:

Can you replace the 220uf 25v capacitor on the main board(the one that handles the inputs)? I have attached a picture of the capacitor and its surroundings. Please reply with the height of the capacitor and all of the text on top of the capacitor.
