Hello lads.
After unsuccessful searches on the Internet, I came to you asking for help in identifying a component. It is located in the LCD panel control board circuit.
I will be sincerely glad for your help!

So power out, supply, AC in and what ever in from the left.
Above parts are uncertain and ground must go under it.
Has K-component more than two contacts?

Buck regulator - unfortunately there are about a gazillion options for what it could be - searching by package and pinout would be a start but likely still dozens to hundreds of possibilities
