What the heck is the name of Blue part in this board ?

[partzan]

Hello ,
I find out my monitor smells not good and it starts to turn off after 1 or 2 hours working.
so I opened it up and I found this Blue part was the problem, but can somebody tell me what is the name of this rectangular Blue part please ?
thank you.

Board level repairs are a pain in the butt.
