Problem with my HANNS G HG281D

[axl1]

Hello guys,
Hope you are fine.
I have an issue with my HANNS G HG281D.
It began like this: it wasn't possible to turn it on. I changed two caps that were bulged and anothers.

When I turned it on, the green led turned on blue,the screen became blank for one second and after that became black. The led changed to orange.
There was a smell of something burning. So, I found what burned and you can see it in the picture below.
Is it possible that this component burned because of card where I cahnged the caps?
Is it possible to repair ir?
Thank you very much for your answers.

Do I have to change the whole card where there is the burned component?
But if I do, it wont do it again ? Does it come from the card before? Non one has an Idea?

That burnt parts looks to be Ferrite Bead (FB??), it is very small value inductor use for filtering high frequency.
In this case the Power supply Voltage is fed into one end of that FB, the output on the other end is connected to load, so you probably has shorted out components on the output side of FB so too much current flown through it and burn it up.

"I changed two caps that were bulged and anothers." Caps on which board that you replaced?

Hello,
Thank you for your answer.
I changed the two big ones as shown in the picture and the three little ones. They weren't bulged but I changed them because I saw in the forum that it is better.
I'll have a look to see if there is shorted components and I'll telle you.

Thank you

BTW, you will also need to replace the two caps on the logic board too once you find out hwat shorted out on that logic board.
