TV Motherboard Replacement Reference

Hello, my TV recently broke down. Not having the budget to replace it, I'm looking into getting it repaired.
I need to change my motherboard, but there are a lot of similar references and I'm wondering if they are not compatible.
What references should I look at?
Mine is a Samsung TV: UE46ES6570 bn94-05625t.

I found one with difficulty online, but it’s a bn94-05625u from a UE55ES6540. Is it compatible? What should I look for in references to avoid mistakes?
Best regards.
