Hot Pixil ?

[nochance]

In my Nikon 5700 images, I have a square of 4 pixils that are white, surrounded by 2 red pixils on both sides, top and bottom. I guess that's what is called a "hot pixil?"

Is there anything that can be done about it? Would I have to send it in for repair? It's not so bad now with so few pixils affected, but it makes me wonder about the future.

Thank you for your advice.

Bob
